Can I use frozen blackberries instead of fresh ones?

Yes, you can use frozen berries if fresh ones are not in season. Do not thaw them first, as they will release too much juice and make the crust soggy during the baking process. Instead, toss them with a teaspoon of cornstarch before baking to help thicken the excess liquid.

How should I store leftover dump cake?

Cover the baking dish tightly with foil or transfer leftovers to an airtight container. Store the cake in the refrigerator for up to four days to keep the fruit fresh and prevent spoilage. Reheat individual slices in the oven at 300 degrees Fahrenheit until warmed through.

Why is my dump cake topping powdery or dry in spots?

This happens when the butter slices do not melt evenly over the dry cake mix during baking. To fix this, you can place thin slices of butter directly onto any dry floury spots about fifteen minutes before the cake finishes baking. This helps the dry flour absorb the fat and bake into a beautiful crust.

Can I make this dessert in a slow cooker?

Yes, you can prepare this rustic dish in a slow cooker by layering the ingredients in the same order. Cook on high for two to three hours or on low for four hours. Make sure to prop the lid open slightly with a wooden spoon during the last thirty minutes to help the topping crisp up.

Can I substitute the butter pecan cake mix with another flavor?

While the butter pecan flavor provides a wonderful nutty warmth, you can easily use yellow, white, or spice cake mix. Each option will bring a different character to the dessert depending on the season. Always match the butter toppings carefully to ensure the flour is fully hydrated.

Do I need to mix the ingredients together before baking?

No, you should never stir the layers of a dump cake together. The beauty of this recipe relies on the distinct, rustic layers of bubbling fruit and melted butter cake. Stirring the mixture will result in a dense, paste-like texture instead of a light, craggy topping.

Can I freeze this dessert after it has been baked?

You can freeze the baked cake once it has cooled completely to room temperature. Wrap the baking dish tightly in plastic wrap and aluminum foil, and store it in the freezer for up to three months. Thaw it overnight in the refrigerator before reheating in a warm oven.

Easy Blackberry Dump Cake With Butter Pecan Cake Mix Warm

Description

This rustic, farmhouse-style dessert layers fresh late-summer blackberries with a fragrant butter pecan cake mix and salted butter. It is a simple, comforting bake that celebrates the deep, tart flavors of wild berries and a satisfyingly crunchy, golden crust.

Ingredients

6 cups fresh blackberries
1 tablespoon fresh lemon juice
3 tablespoons brown sugar
1 box (approx. 15 oz) butter pecan cake mix
12 tablespoons salted butter, sliced into thin pats

Cook Mode Prevent your screen from going dark

Instructions

Preheat and grease. Preheat the oven to 350°F and lightly grease a 9×13-inch baking dish with a small pat of butter.
Prepare blackberry base. Scatter the fresh blackberries evenly in the baking dish and toss gently with the lemon juice.
Add brown sugar. Sprinkle the brown sugar uniformly over the berries to help create a syrupy, jammy consistency.
Layer cake mix. Evenly spread the dry cake mix over the berries and use the back of a spoon to smooth it into a level layer.
Arrange butter slices. Place the thin butter pats in neat, even rows across the surface of the dry cake mix.
Bake until golden. Bake for 45 to 60 minutes until the edges are deep golden brown and the fruit juices are bubbling around the sides.

Notes

Use fresh berries instead of frozen to prevent a watery consistency in the final dessert.
Ensure the butter is chilled before slicing to achieve even distribution and prevent premature melting.
Let the dump cake rest for at least 15 minutes after removing from the oven to allow the fruit juices to thicken.
If dry spots of cake mix remain after baking, place small additional butter slivers on those patches and return to the oven briefly.
