Step‑by‑Step Instructions for Peanut Butter Cup Dump Cake
Step 1: Mix Pudding and Milk
In a large mixing bowl, whisk together the instant chocolate pudding mix and 2 cups of milk until the mixture is smooth and creamy. This should take about 2 minutes. Look for a thick consistency as you combine the ingredients, which will help create the rich base for your Peanut Butter Cup Dump Cake.
Step 2: Add Cake Mix
Next, slowly incorporate the chocolate cake mix into the pudding mixture, stirring gently to combine. Use a spatula or wooden spoon for about 1-2 minutes until there are no visible dry spots. The batter will be thick and fudgy—this is a great sign that your cake is going to be wonderfully moist!
Step 3: Incorporate Peanut Butter Cups
Now, take your peanut butter cups and roughly chop them into smaller pieces. Fold them into the batter, ensuring they are evenly distributed throughout. The pieces should create delightful pockets of melted peanut butter flavor within the cake. This step should take about 1 minute for a thorough mix.
Step 4: Bake
Preheat your oven to 350°F (180°C) while you prepare the baking dish. Grease a 13 x 9-inch baking dish with cooking spray or butter. Pour the Peanut Butter Cup batter into the prepared dish, spreading it evenly with a spatula. Bake in the preheated oven for approximately 25 minutes, checking for doneness with a toothpick; it should come out with a few moist crumbs attached.
Step 5: Cool and Serve
Once baked, remove the Peanut Butter Cup Dump Cake from the oven and allow it to cool for about 10 minutes. This cooling period helps enhance the fudgy texture. Serve warm, ideally with a generous scoop of vanilla ice cream on top for the ultimate indulgent experience!

Peanut Butter Cup Dump Cake Recipe FAQs
What should I look for when selecting peanut butter cups?

What is the best way to troubleshoot if my dump cake is too dry?
If your dump cake turns out dry, it may be due to overbaking. To prevent this next time, keep an eye on it and start checking for doneness around the 20-minute mark.
