How to Make The Easiest, Fudgiest Peanut Butter Cup Dump Cake Ever!
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C) and greasing a 9×13 inch baking pan. This step ensures the cake will bake evenly and release easily when done, making clean-up a breeze.
Step 2: Mix the Base Ingredients
In a large bowl, combine the chocolate cake mix, instant chocolate pudding mix, and milk. Stir these together until everything is well incorporated and smooth. This mix is the foundation for that irresistible fudgy texture.
Step 3: Add the Peanut Butter
Next, fold in the creamy peanut butter until the batter is beautifully blended and silky. The peanut butter not only gives flavor but also enhances the moist, fudgy feel of the cake.
Step 4: Fold in the Chocolate Chips and Peanut Butter Cups
Gently fold in the chocolate chips and chopped peanut butter cups, creating delightful pockets of melted chocolate and peanut butter throughout the cake. If your batter feels too thick, don’t hesitate to add a splash more milk to make it easier to work with.
Step 5: Bake the Cake
Pour the luscious batter into the greased baking pan, spreading it out evenly. Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean. The baking time perfectly sets the cake while keeping it delectably fudgy.
Step 6: Cool Slightly and Enjoy!
Let your cake cool just enough to set, but not too long—you want it warm so the chocolate and peanut butter are still wonderfully gooey. This is the moment to get excited about slicing into your creation!

Absolutely! Using crunchy peanut butter adds a little extra texture which can be delightful, though creamy will give a smoother batter. Choose based on your preference.

What if I don’t have peanut butter cups? Can I skip them?
You can omit the peanut butter cups if needed; the cake will still be delicious. However, those cups add a lovely chewiness and an extra burst of peanut butter and chocolate flavors.
Is this cake gluten-free?
This recipe depends on the cake mix and pudding mix you use. To make it gluten-free, choose certified gluten-free versions of these mixes.
Can I make this cake in a different sized pan?
You can, but baking times might vary. A larger pan will result in a thinner cake and shorter baking time, while a smaller pan will need longer baking to set properly.

- 1 cup milk (whole, add more if needed)
