The Inspiring Story Behind This Award-Winning Dessert


Every truly great recipe has a captivating origin story, and this Berry Rhubarb Crumble is no exception. Its journey to becoming a beloved, prize-winning dish is quite remarkable and speaks volumes about the passion and creativity of home bakers. I had the distinct pleasure of discovering this exceptional recipe through my dedicated recipe and food Facebook group, where enthusiastic home cooks gather to share their culinary triumphs and discoveries.

Among our talented members is Pat Harmon, a true “recipe contester” – a title earned through her consistent ability to craft incredible dishes and win top honors in cooking competitions. Pat generously shared her original “Very Berry Rhubarb Cobbler” within our group, revealing its impressive history: a grand prize winner of $5,000 back in 1997! She recounted her exciting experience entering Reddi-Wip’s “50 Fruit Salute” contest, which featured two tiers of prizes: $50 for one winner per state, and the highly coveted grand prize of $5,000.

Pat was already a seasoned contester, having been a finalist in the prestigious Pillsbury Bake-Off (an achievement she would repeat two more times!). She drew upon her extensive experience and culinary intuition to create something truly special. Her inspiration for this particular recipe stemmed from a deep appreciation for the classic pairing of rhubarb and strawberries. “I was a big fan of rhubarb and strawberries together,” Pat shared, “so I changed it up a bit by adding blueberries.” This thoughtful addition elevated the fruit blend, introducing another layer of sweetness and a beautiful visual contrast. Furthermore, an apple crisp topping she had once enjoyed sparked the brilliant idea to incorporate almonds into her crumble, providing a delightful textural contrast and a subtle, nutty flavor that complements the fruit perfectly.

The culmination of her creativity and expertise led to a day she’ll never forget: “I received two letters in the mail the same day. One said I had been chosen for the $50 Pennsylvania prize and the other said I had won the grand prize as well!” Imagine the sheer excitement and pride of receiving such incredible news! Pat’s dedication to creating innovative and delicious recipes truly paid off, and we, her fellow food enthusiasts, are incredibly fortunate that she chose to share her winning creation with our community. This crumble isn’t just a recipe; it’s a testament to the joy of cooking and the thrill of discovery.

Cobbler, Crisp, or Crumble? Demystifying Dessert Toppings


You might notice a slight difference in nomenclature: Pat originally titled her recipe “Very Berry Rhubarb Cobbler,” while I’ve chosen to call it “Prize Winning Rhubarb Crumble.” This often sparks a friendly and sometimes passionate debate among bakers about the precise definitions of these beloved fruit desserts. While they all feature a delicious fruit filling crowned with a delightful crust, there are subtle distinctions in their toppings that set them apart:

  • Fruit Crisp: Characterized by a topping that typically includes oats, mixed with flour, sugar, butter, and often spices and nuts. When baked, the oats and other ingredients create a wonderfully crunchy, “crisp” texture, offering a satisfying contrast to the soft fruit below.
  • Fruit Cobbler: Features a dropped biscuit-like topping over the fruit filling. These dollops of dough are usually made with a leavening agent and, when baked, expand and brown, giving a rustic, uneven, “cobbled” appearance, reminiscent of a cobblestone street. The topping tends to be softer and more cake-like than a crisp or crumble.
  • Fruit Crumble: Similar to a crisp but generally distinguishes itself by the absence of oats in its topping. Instead, a crumble topping is a rich, buttery mixture of flour, sugar, and butter, often with the delightful addition of nuts like almonds, pecans, or walnuts. This combination creates a tender, sandy, and truly “crumbly” texture that melts in your mouth.

Given that Pat’s ingenious addition of sliced almonds aligns perfectly with the characteristics of a crumble (no oats, but nuts are a welcome inclusion), and to maintain clarity and consistency for a wider audience, “crumble” felt like the most fitting and accurate description for this incredible dessert. Rest assured, whatever you choose to call it, the taste remains undeniably spectacular, delivering a perfect harmony of sweet, tangy, and rich flavors.

Key Ingredients: Selection and Smart Substitutions


Crafting the perfect Berry Rhubarb Crumble begins with selecting high-quality ingredients. Paying attention to these details will ensure your dessert is bursting with flavor and boasts the ideal texture. Below are some tips for choosing the best components and suggestions for thoughtful substitutions to make this recipe your own:

  • Rhubarb: For the most vibrant flavor and texture, always aim for fresh rhubarb. Look for stalks that are firm, crisp, and free from blemishes or signs of wilting. The color can range from a vibrant reddish-pink to a paler green, depending on the variety, so don’t assume redder is always sweeter. Rhubarb is typically in season from early spring to early summer, making this crumble a perfect seasonal delight. If fresh rhubarb isn’t available, frozen rhubarb is an acceptable alternative; simply ensure you thaw it completely and drain any excess liquid thoroughly before chopping and mixing. This step is crucial to prevent a watery filling.
  • Berries (Strawberries & Blueberries): Fresh berries are highly recommended for this recipe, as they offer the brightest flavor and maintain a firmer texture during baking. Choose plump, brightly colored strawberries and blueberries that are free from mold or soft spots. If using frozen berries, thaw them completely and gently pat them dry with paper towels to remove any extra moisture. Since frozen fruits tend to release more liquid, you might need to slightly increase the amount of cornstarch in the fruit filling by an extra half tablespoon. This adjustment will help ensure the mixture thickens properly and achieves that desirable luscious consistency. Feel free to experiment with other berry combinations as well, such as raspberries or blackberries, for a unique twist.
  • Almonds: Pat’s original, prize-winning recipe specifically calls for sliced almonds. These contribute a beautiful visual appeal to the topping and provide a delicate, satisfying crunch without being overly hard. However, don’t hesitate to customize based on your preference or what you have on hand! Chopped pecans or walnuts would also make excellent additions, offering a different depth of flavor and a slightly bolder texture. If you or your guests have a nut allergy, or if you simply prefer a nut-free option, you can omit the almonds entirely. Alternatively, substitute them with an equal amount of additional all-purpose flour or, for a slight variation, a small sprinkle of rolled oats, which would lean towards a “crisp” texture.
  • Balsamic Vinegar: This might seem like an unconventional ingredient for a sweet dessert, but trust me, it’s a secret weapon! A small amount of balsamic vinegar works wonders by enhancing the natural sweetness and introducing a subtle tang to the fruit, adding a complexity and depth that truly makes the flavors sing. It doesn’t make the crumble taste like vinegar; rather, it brightens and amplifies the distinct notes of the berries and rhubarb, creating a more sophisticated and well-rounded flavor profile.
  • Cornstarch: This essential ingredient serves as a crucial thickening agent, ensuring your fruit filling achieves a perfectly luscious, jam-like consistency rather than being runny. It helps bind the fruit juices into a glorious sauce. Ensure you mix it thoroughly with the sugar and fruit to prevent any lumps, guaranteeing a smooth and delightful filling.

How to Make This Prize-Winning Rhubarb Crumble: A Step-by-Step Guide


Creating this delicious Berry Rhubarb Crumble is a straightforward process that culminates in truly spectacular results. Follow these detailed steps to bake your own prize-winning dessert, perfect for any occasion. For a complete printable version with all exact measurements, please refer to the comprehensive recipe card below.

  1. Prepare Your Oven and Baking Dish: Begin by preheating your oven to 375º F (190º C). This ensures the oven is at the correct temperature for even baking. Next, lightly grease the bottom and sides of a 13×9 inch baking pan with butter or cooking spray. This crucial step prevents the fruit mixture from sticking and ensures an easy release when serving.
  2. Prepare the Fruit: Thoroughly wash and prepare your fresh fruit. Start by chopping the rhubarb stalks into uniform 1-inch pieces. Then, hull and thinly slice the fresh strawberries. If you are using frozen fruit, ensure it is fully thawed before use, and gently squeeze or pat dry any excess liquid to avoid a watery filling.
  3. Combine the Fruit: In a large mixing bowl, gently combine the chopped rhubarb, sliced strawberries, and fresh blueberries. Toss them together lightly to distribute them evenly.
  4. Sweeten and Thicken the Filling: Add the granulated sugar, cornstarch, and balsamic vinegar directly to the fruit mixture in the bowl. Stir everything thoroughly, making sure to scrape the bottom of the bowl and turn the fruit so that every single piece is evenly coated in the sugary and thickening mixture. You’ll observe the fruit gaining a beautiful, glossy coating.
  5. Transfer to Baking Pan: Carefully pour the coated fruit mixture into your prepared 13×9 inch baking pan. Spread the fruit evenly across the bottom of the pan to ensure consistent baking. Set this aside while you proceed to prepare the irresistible crumble topping.
  6. Prepare the Crumble Topping: In a separate medium-sized mixing bowl, combine the all-purpose flour, granulated sugar, salt, and the sliced almonds. Stir these dry ingredients together well. Next, crack in the large egg and mix until the mixture begins to come together and forms distinct, crumbly clumps. Use your fingertips to gently toss and combine everything completely, ensuring that you achieve that perfectly desirable crumbly texture. Be careful not to overmix.
  7. Assemble the Crumble: Generously sprinkle the prepared crumble topping evenly over the sugared fruit mixture in the baking pan. Try to get an even layer for consistent browning. Then, evenly drizzle the melted unsalted butter over the entire surface of the crumble topping. This butter is key for achieving a beautifully golden brown and crispy crust.
  8. Bake to Perfection: Carefully place the baking pan into your preheated oven. Bake for approximately 35-40 minutes. You’ll know your crumble is perfectly baked when the topping is a gorgeous golden brown color and the fruit mixture underneath is visibly bubbling vigorously around the edges, indicating that it’s hot, tender, and the juices have thickened.
  9. Cool and Serve: Once baked, carefully remove the pan from the oven and transfer it to a cooling rack. Allow the crumble to cool slightly until it’s just warm to the touch. This brief cooling period helps the fruit filling set to its ideal consistency. Serve warm, ideally topped with a generous, chilly scoop of premium vanilla ice cream for the ultimate dessert experience, or with a dollop of fresh whipped cream.

Frequently Asked Questions & Expert Tips for Success


How do I store leftover Prize Winning Rhubarb Crumble?

To maintain its freshness and delicious flavor, any leftover Berry Rhubarb Crumble should be stored in an airtight container. Refrigerate promptly for up to 3-4 days. While the topping might lose a little of its initial crispness in the refrigerator, the flavors will still be wonderful. For the best texture when reheating, warm individual servings in the oven at a moderate temperature (around 300°F / 150°C) until heated through, or briefly in the microwave for a quicker option. Avoid overheating in the microwave, which can make the fruit too soft.

Can I make this crumble ahead of time?

Yes, absolutely! This crumble is very accommodating and can be prepared in advance, making it perfect for entertaining or busy schedules. You have a few convenient options:

  1. Assemble and Refrigerate: You can prepare the fruit filling and the crumble topping separately. Store the fruit mixture covered tightly in the baking dish in the refrigerator for up to 24 hours. Keep the crumble topping in a separate airtight container in the fridge. Just before you’re ready to bake, sprinkle the topping over the fruit and proceed with baking as directed in the recipe.
  2. Bake and Reheat: Alternatively, you can bake the entire crumble recipe, let it cool completely to room temperature, and then refrigerate it. When it’s time to serve, reheat the entire dish in a preheated oven at 350°F (175°C) for about 20-30 minutes, or until it’s thoroughly warmed through. If the topping starts to brown too much during reheating, loosely cover the dish with aluminum foil.
Can I freeze this Berry Rhubarb Crumble?

Indeed, this crumble freezes beautifully, making it an excellent candidate for meal prep or having a delicious dessert ready on demand.

  • Baked Crumble: After baking, allow the crumble to cool completely to room temperature. Wrap the baking dish tightly with plastic wrap, then an additional layer of heavy-duty aluminum foil. Label and freeze for up to 2-3 months. To serve, thaw overnight in the refrigerator, then reheat in a 350°F (175°C) oven until warm and bubbly, typically about 30-40 minutes.
  • Unbaked Crumble: Assemble the crumble as directed in the instructions, but do not bake it. Cover the unbaked dish tightly with plastic wrap and then with aluminum foil. Freeze for up to 2 months. When you’re ready to bake, remove it from the freezer, unwrap, and bake directly from frozen at 375°F (190°C). This will require a longer baking time, usually about 60-75 minutes, or until the topping is golden brown and the fruit mixture is bubbly. You may need to cover it loosely with foil during the last 20 minutes to prevent the topping from over-browning.
My crumble topping is too dry/not crumbly enough. What went wrong?

The key to a perfect crumble topping is striking the right balance between fat and dry ingredients. If your topping feels too dry or doesn’t clump well, it might be due to slightly less butter than ideal, or perhaps a difference in flour absorption. Conversely, if it’s not crumbly enough and forms a solid mass, you might have overworked the mixture, or your butter might have been too warm. For a more traditional “streusel” texture, ensure your butter is cold and cut into small cubes, then “cut it in” (using your fingers, a pastry blender, or a fork) into the flour mixture until pea-sized crumbs form, before adding the egg. The egg should then be just incorporated to maintain distinct clumps. Avoid overmixing once the egg is added.
