This impossibly simple dessert transforms just three pantry staples—boxed yellow cake mix, canned blueberry pie filling, and butter—into a warm, bubbling cobbler with golden, crispy top layer and sweet, fruity filling underneath. The genius lies in the method: layering dry cake mix with fruit filling and grated butter creates the signature cobbler texture without mixing, measuring, or complicated technique, making this the ultimate dessert solution when you need something homemade and comforting with minimal effort and maximum deliciousness.

Ingredients You’ll Need
For the Cobbler:
- 1 box (15.25 oz) yellow cake mix – Forms both the bottom absorbing layer and the top crispy topping; use standard yellow, butter, or vanilla cake mix
- 40 oz (2 cans, 21 oz each) blueberry pie filling – Provides the sweet, fruity center; use quality pie filling like Comstock or Duncan Hines for best results
- 1 stick (½ cup) butter, cold – Creates the rich, crispy topping when grated over the dry cake mix; must be cold from refrigerator for easy grating
For Serving:
- Vanilla ice cream (optional but highly recommended) – Adds creamy, cold contrast to the warm cobbler and melts into the fruity filling deliciously
Step-by-Step Instructions
Preheat the Oven Preheat your oven to 375°F (190°C) and position a rack in the center. This moderate temperature allows the cobbler to bake through completely while developing golden-brown color on top without burning.
Prepare the Baking Pan Generously spray a 9×13-inch baking pan with cooking spray or grease thoroughly with butter, making sure to coat the bottom and sides completely. This prevents sticking and ensures easy serving when the cobbler is finished.
Create the Bottom Layer Open the box of yellow cake mix and sprinkle half of the dry mix (about 2 cups) evenly across the bottom of the prepared pan. Use your hands or a spoon to distribute it uniformly, creating a consistent base layer that will absorb moisture from the fruit filling during baking. Don’t pack it down—just spread it in an even, loose layer.
Add the Blueberry Filling Open both cans of blueberry pie filling and spoon the entire contents over the cake mix layer, distributing the filling as evenly as possible across the surface. Use a spoon to gently spread it around, trying to minimize disturbing the cake mix underneath—some mixing at the edges is fine and inevitable, but try to maintain distinct layers for best texture contrast in the finished cobbler.
Apply the Top Cake Mix Layer Sprinkle the remaining half of the cake mix evenly over the blueberry filling, again distributing it uniformly from edge to edge. This top layer will transform into the golden, slightly crispy crust during baking as it absorbs butter and caramelizes.
Grate the Cold Butter Remove the stick of butter from the refrigerator—it should be very cold for easiest grating. Using the large holes of a box grater or cheese grater, grate the entire stick of butter directly over the top of the cake mix layer, distributing the shreds as evenly as possible across the entire surface. The grated butter will melt during baking and create pockets of rich, buttery crust throughout the topping.
Bake Until Golden Place the assembled cobbler on the center oven rack and bake for approximately 40-45 minutes, checking at the 40-minute mark. The cobbler is done when the top is deep golden brown, the edges are bubbling vigorously, and you can see the fruit filling bubbling up around the edges. The topping should look crispy and slightly craggy rather than smooth and pale.
Cool and Serve Remove the cobbler from the oven and let it cool for 10-15 minutes before serving—this allows the filling to thicken slightly and makes portioning easier. Scoop generous servings into bowls and top with a large scoop of vanilla ice cream that will melt into the warm fruit and create an irresistible sauce. Serve while still warm for the best texture contrast between the crispy topping and soft filling.
Recipe Notes & Tips
- Butter Temperature – The butter must be cold for successful grating; if it’s too soft, it will smush instead of grating into shreds. Pop it in the freezer for 5-10 minutes if needed.
- Cake Mix Brands – Any standard yellow cake mix works; Betty Crocker, Duncan Hines, and Pillsbury all perform similarly in this application.
- Pan Size Matters – A 9×13-inch pan is ideal; using a smaller pan makes the layers too thick and prevents proper cooking, while a larger pan makes them too thin and dry.
- Fruit Distribution – Don’t worry about perfect, smooth layers; some unevenness is natural and won’t affect the final result significantly.
- Checking Doneness – Look for deep golden color and bubbling around all edges; if the top browns too quickly before the edges bubble, tent loosely with foil and continue baking.
- Make-Ahead Possibility – While best served fresh, you can assemble this completely and refrigerate for several hours before baking; add 5-10 minutes to baking time when starting from cold.

Storage & Serving Tips
- Room Temperature Holding – The cobbler stays delicious at room temperature for about 2 hours after baking; beyond that, refrigerate to prevent spoilage.
- Refrigerator Storage – Cool completely, cover tightly with foil or plastic wrap, and refrigerate for up to 4 days; the topping will soften but flavor remains excellent.
- Reheating Instructions – Warm individual portions in the microwave for 30-60 seconds, or reheat the entire pan covered with foil at 350°F for 15-20 minutes.
- Serving Portions – Cut into 12 generous squares for standard dessert servings, or 15-16 smaller pieces when serving as part of a larger dessert spread.
Creative Variations to Try
- Cherry Cobbler – Replace blueberry filling with cherry pie filling for classic cherry cobbler that’s equally delicious and visually stunning.
- Peach Cobbler – Use peach pie filling for Southern-style cobbler; add ½ teaspoon cinnamon to the bottom cake mix layer for extra warmth.
- Mixed Berry – Combine two different pie fillings like blueberry and cherry, or use mixed berry filling for complex fruit flavor.
- Chocolate Chip Addition – Sprinkle 1 cup chocolate chips over the fruit layer before adding the top cake mix for chocolate-berry combination.
Troubleshooting Common Issues
- Soggy Topping – Not enough butter or insufficient baking time; make sure to use the full stick of butter and bake until deeply golden and bubbling at edges.
- Dry Texture – Too much cake mix or not enough fruit filling; measure the layers carefully and ensure you’re using the full 40 oz of pie filling.
- Burnt Top – Oven running hot or positioned too close to heating element; reduce temperature by 25°F and tent with foil if browning too quickly.
- Undercooked Center – Pan too deep or oven temperature too low; ensure you’re using a 9×13-inch pan and verify oven temperature with thermometer.
Why This Recipe Works
This deceptively simple cobbler succeeds through smart layering that creates the essential cobbler characteristics—crispy topping, sweet fruit filling, tender cake-like bottom—without any mixing or complicated technique. The bottom layer of dry cake mix absorbs moisture from the pie filling during baking, transforming into a tender, cake-like base similar to traditional cobbler dough. The fruit filling provides concentrated sweetness and moisture while maintaining distinct pockets of whole berries and thick sauce. The top layer of cake mix acts as a streusel-like topping that becomes crispy and golden where the grated butter melts into it, creating rich pockets of buttery crust. Grating the cold butter rather than melting it ensures even distribution across the entire surface—as it melts during baking, it flows into the dry cake mix, activating the leavening agents and creating that signature crispy-tender texture. The moderate oven temperature (375°F) allows everything to bake through completely while developing appealing golden-brown color without burning. The lack of mixing means distinct layers remain throughout, providing textural variety in every spoonful—crispy top, soft cake middle, sweet fruity bottom—that makes each bite interesting. Using pie filling rather than fresh fruit eliminates the need to sweeten, thicken, or prepare the fruit separately, while providing consistent results regardless of berry season or quality. At approximately 320 calories per serving, this delivers satisfying dessert indulgence in reasonable portions, especially when you consider that a single serving provides enough sweetness and comfort to fully satisfy dessert cravings without requiring enormous portions.
