What is a Dump Cake?

Dump cake is an American dessert that originally included dumping fruit into a pan, then dumping a box cake mix on top of the fruit before drizzling melted butter over the top.

You can certainly buy a keto cake mix and dump some of it on top of the blueberry mix, but our way is less expensive.

This keto berry dump cake has a soft blueberry filling and a soft almond and coconut flour topping. It's best served warm, and with keto ice cream.

Ingredients in Keto Dump Cake:

Blueberries - The star of this keto dessert, lower in carb, and full of nutrients. We're using frozen blueberries in this recipe but you can use fresh blueberries if you like.

Granulated Sweetener - We like to use Lakanto or Swerve. Both the white and golden granulated sweeteners work in this recipe as a sugar substitute.

Lemon Juice - Lemon works really well with blueberries. It adds a little acidity, flavor, and really helps pull everything together. If you like lemon flavor, try our keto lemon cake or keto lemon bars next.

Coconut Flour - For flavor, we're using a combination of nut flours.

Almond Flour - We're using both almond flour and coconut flour to help with texture as well.

Baking Powder - Adds a little bit of leavening agent.

Ground Cinnamon - For flavor. Believe it or not, cinnamon goes really well with blueberries. Think blueberry cobblers and crisps!

Salt - For flavor and to help enhance other flavors.

Butter - For flavor, texture and to help soften the almond flour and coconut flour.

Tips for Making this Blueberry Dump Cake

You can use fresh blueberries instead of frozen blueberries if you prefer. If you use fresh blueberries, you won't need to bake the dump cake as long as with frozen berries.

Reduce the baking time by 5-10 minutes to avoid over-baking.

You may want to play around with the amount of sweetener in the cake. Use more or less sweetener according to your personal taste.

Bake your dump cake long enough to allow the top to brown adequately, but not long enough to dry it out. Upon cooling, the topping will soften into a consistency reminiscent of bread pudding.

Dairy Free Dump Cake Option

You can easily make this dump cake dairy-free if needed. If you don't consume dairy by preference or can't due to an allergy or intolerance, simply replace the butter with melted coconut instead.

Your paleo blueberry dump cake will come out just as delicious as the dairy butter version does.

If you're in the market for more dairy-free blueberry desserts, our keto berry smoothie is another great recipe that uses almond milk in place of dairy milk.

Working With Almond Flour

Not all almond flours are alike. Make sure to use a fine ground almond flour.

If the almond flour is stored in the refrigerator or freezer, bring it to room temperature before using. Cold almond flour absorbs more of the wet ingredients.

Stir the almond flour, then spoon it into the measuring cup and level. Never dip the measuring cup into the almond flour. It will add too much almond flour to the recipe.
