Crockpot Lemon Blueberry Dump Cake Recipe
We love making slow cooker dump cakes! They are so easy to make and always taste amazing.
This Lemon Blueberry Dump Cake is great for summer parties, barbecues, or family dinners. So delicious, and you don't have to stress about getting it out of the oven. Just dump the ingredients in the Crock Pot; it works for you instead of making you do the work!
Here is a quick overview of the simple ingredients needed to make an epic Crock Pot Lemon Blueberry Dump Cake! The printable recipe card at the bottom of the post includes specific measurements and step-by-step instructions.
Optional Garnish - Fresh blueberries, cherries, a scoop of vanilla ice cream
- Microwave Butter Cover: I swear by these lid covers to help prevent butter splatters when melting butter in the microwave. I have had way too many butter explosions while baking. This lid cover helps keep the butter in the bowl and not on the roof of your microwave.
- CrockPot: We suggest using a CrockPot with a digital timer that automatically switches the slow cooker to warm after a set amount of time, as this helps ensure your dinner cooks perfectly without stressing about the cooking time.
How to Make Crock Pot Lemon Blueberry Dump Cake
I've included complete instructions in the printable recipe card at the bottom of the post, but here's a quick version.
- Spray slow cooker with non-stick cooking spray.
- Dump the lemon cake mix, blueberry pie filling, and butter.
- Cook on low
Preparation and Storage
Make-Ahead + Storage: We like serving this lemon blueberry dump cake warm. However, it is make-ahead-friendly; cover it in aluminum foil or plastic wrap after baking, refrigerate it, or leave it on your countertop, depending on whether you prefer it cold or room temperature.
Refrigerated leftovers will remain good for about five days, while those left at room temperature will last about two days. Make sure to store in an airtight container in the refrigerator.
Freezing/How to Freeze: Leftover dump cake freezes for up to three months. Wrap it securely in plastic or aluminum foil to keep the freezer burn at bay.
How to Reheat: Thaw leftovers overnight in the fridge or on your countertop until edible for the best texture.
Substitutions: You can make this with melted butter or sliced butter. You will get a crumbier result and may have a few dry spots. If you use melted butter, you can mix the cake mix into the melted butter or pour it over the top of the cake mix.
If you can't find a lemon cake mix you can easily use a yellow cake mix. For the lemon flavor add in lemon zest
Vegetarian + Vegan Options: This recipe is vegetarian and vegan-friendly as long as your ingredients are labeled accordingly! Most canned pie fillings are safe for a vegan diet. Vegans should also replace the butter with a plant-based alternative.
Gluten-Free: Use a gluten-free cake mix and pie filling to make this recipe gluten-free.
Larger Group/More Servings: We like to use two cans of blueberry pie filling to make this dump cake last longer. You can use one can if that is all you have. If you are serving this to a group, you can easily double this recipe, but watch the cooking time and switch the slow cooker to warm to keep it warm but not cooking.
Sugar-Free: Use a sugar-free cake mix and pie filling to make this recipe sugar-free.
