This is one of the best Crockpot dessert recipes I have ever made. It’s nice to be able to bake a cake without the oven but this Crockpot Peanut Butter Cup Cake kicks it up to a whole new level.
You are going to need to gather your ingredients and get your crockpot ready. I used my large 6 qt crockpot and it was perfect. Honestly I don’t think this would work as good in a smaller crockpot.
In large bowl, beat cake mix, water, eggs, 1/2 cup peanut butter and the butter with electric mixer on low 30 speed seconds, then on medium speed 2 minutes, scraping bowl.
You can totally make this gluten free by using a gluten free cake mix. In fact, try this homemade yellow cake mix recipe. You can make it regular or gluten free & it works perfect in this recipe.
Take 2/3 cup of your cake batter and put it in a separate bowl. Mix in the chocolate syrup and until batter is fudgey.
Now in your crockpot place 1/2 of your pb cake mix…then top with the chocolate cake mix.
Then top with the remaining peanut butter cake batter. Use a butter knife to swirl the chocolate and peanut butter batter together.
Place on lid and cook on hight for 1 hour 45 mins to 2 hours 15 mins. It really will vary depending on your crockpot. Just make sure a toothpick inserted into the center of the cake comes out clean. Your cake will also start to pull way from the walls of your crockpot.
When your cake is done turn off the crockpot and remove the crock. Set out to cool.
While the cake cools make the Peanut Butter glaze. Spread it over the top of the cake. Drizzle with more chocolate syrup and top with the chopped pb cups.
