Ingredients
Scale
Main Ingredients
- Cooking spray, as needed for greasing
- 2 (20-ounce) cans blueberry pie filling
- 1 teaspoon lemon zest (from 1 large lemon)
- 1 box vanilla cake mix (approx. 15.25 ounces)
- ½ cup chopped walnuts
- 1 stick (½ cup) salted butter, cut into small pieces
Instructions
- Preheat and Prep: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan thoroughly with cooking spray to prevent sticking.
- Layer Ingredients: Spread the blueberry pie filling evenly across the bottom of the prepared baking pan. Sprinkle the lemon zest evenly over the pie filling, imparting a fresh citrus aroma. Then, evenly sprinkle the dry vanilla cake mix over the blueberry layer, ensuring full coverage. Follow by evenly distributing the chopped walnuts on top of the cake mix. Finally, dot the surface with small pieces of the salted butter, which will melt during baking to create a rich, golden crust.
- Bake: Place the pan in the preheated oven and bake for about 1 hour. Check occasionally to make sure the top does not darken excessively; if it begins to brown too much, loosely cover the pan with aluminum foil to protect the cake.
- Cool and Serve: Once baked, allow the cake to cool slightly. This dessert is best served warm, optionally accompanied by a scoop of vanilla ice cream or a dollop of whipped cream for added indulgence.
Notes
- Ensure even spreading of the blueberry filling and cake mix for uniform baking.
- Cover with foil if top browns too fast to prevent burning.
- Use fresh lemon zest for best flavor impact.
- The cake improves in flavor if allowed to rest for 10-15 minutes after baking.
- Store leftovers covered in the refrigerator for up to 3 days.
- Optional toppings include ice cream or whipped cream for extra richness.
