Step-by-Step Instructions on How to Make Peanut Butter Cup Dump Cake

Step 1: Preheat the Oven

Set your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.

Step 2: Mix the Pudding

In a large bowl, whisk together the instant chocolate pudding mix and 3 cups of milk until smooth. Let it sit for 2–3 minutes to thicken slightly.

Step 3: Add the Cake Mix

Pour the dry chocolate cake mix directly into the pudding mixture. Stir gently until mostly combined — don’t overmix! You want that thick, luscious texture.

Step 4: Swirl in Peanut Butter

Warm the peanut butter slightly in the microwave (about 20 seconds) to make it easier to drizzle. Drop spoonfuls over the batter, then use a knife to gently swirl it in.

Step 5: Add Peanut Butter Cups

Sprinkle chopped peanut butter cups evenly over the top. Press them in lightly so they bake into the cake.

Step 6: Bake

Bake at 350°F for 35–40 minutes, or until the edges are set but the center is still slightly gooey. The smell at this point? Pure chocolate-peanut butter heaven!

Step 7: Cool and Serve

Let it cool for at least 15 minutes before serving. The center will be warm, soft, and pudding-like — pure magic with a scoop of vanilla ice cream on top.

I’m kicking myself for not having filmed this moment — the peanut butter just melts into the chocolate in the most satisfying way. Anything but boring!!

What to Serve with Peanut Butter Cup Dump Cake
