Step‑by‑Step Instructions for Chocolate Peanut Butter Dump Cake
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven heats, generously grease a 13×9-inch baking pan with cooking spray or butter to ensure your Chocolate Peanut Butter Dump Cake releases easily after baking. This step is crucial for a perfect, cleanup-free slice!
Step 2: Combine Pudding and Milk
In a large mixing bowl, whisk together the instant chocolate pudding mix and 2% milk until the mixture is smooth and well combined. This will take about 2 minutes of vigorous whisking, resulting in a creamy base for your delicious cake. Ensure there are no lumps for a velvety texture.
Step 3: Mix in Cake Mix
Gently fold in the chocolate cake mix into the pudding mixture. Use a spatula to combine until no dry mix remains; the batter will be thick. This step is critical, as it forms the delightful base of your Chocolate Peanut Butter Dump Cake, so take your time to blend thoroughly.
Step 4: Add Sweet Components
Once the batter is combined, it’s time to add chopped peanut butter cups, peanut butter chips, semisweet chocolate chips, and unsalted peanuts. Stir well to evenly distribute these indulgent ingredients throughout your mixture—this is where the magic happens, bringing your cake to life with layers of flavor!
Step 5: Spread and Bake
Pour the luscious batter into the prepared baking pan, spreading it evenly with your spatula. Bake in the preheated oven for 20-25 minutes. The cake is done when you see the edges start to pull away from the pan and a toothpick inserted in the center comes out with moist crumbs.
Step 6: Cool and Serve
Remove the pan from the oven and allow the Chocolate Peanut Butter Dump Cake to cool completely in the pan. This will take about 30 minutes, letting the flavors settle and the cake firm up for easier slicing. Once cooled, cut into squares and get ready to enjoy a slice of this decadent dessert!

Make Ahead Options
These Chocolate Peanut Butter Dump Cakes are perfect for busy home cooks looking to save time! You can prepare the batter up to 24 hours in advance by combining the pudding mix and milk, then folding in the cake mix and mix-ins, and refrigerating the mixture in an airtight container. This way, when you’re ready to serve, all you have to do is pour the chilled batter into the prepared pan and bake it straight away. To maintain its delightful texture, ensure the batter is covered to prevent drying out. With this prep-ahead option, you’ll get to enjoy that chocolate-peanut bliss with minimal fuss, making it a true lifesaver for any gathering!

Expert Tips for Chocolate Peanut Butter Dump Cake

Chocolate Peanut Butter Dump Cake Recipe FAQs
What should I look for when selecting the ingredients?
Absolutely! When choosing the instant chocolate pudding mix, look for a brand that promotes a rich chocolate flavor, as this sets the foundation for your cake. For milk, go for 2% for a creamy texture, but whole or skim work just as well. The cake mix should be a classic chocolate flavor for the best results, and for the peanut butter cups, select fresh ones without dark spots or squished packaging for top taste.
How should I store leftover Chocolate Peanut Butter Dump Cake?
I often store leftover slices in an airtight container at room temperature for up to 3 days. If you’re keeping it longer, refrigerate it, where it can stay fresh for about a week. However, make sure it’s properly sealed to prevent it from drying out – no one wants a stale slice!
Can I freeze Chocolate Peanut Butter Dump Cake?
Yes, you can! Wrap individual slices tightly in plastic wrap and then place them in a freezer-safe bag. They’ll stay good for 2-3 months. When you’re ready to indulge again, simply thaw overnight in the fridge, and then warm in the microwave for about 10-15 seconds to restore that gooey goodness.
What if my cake doesn’t come out as gooey as I wanted?
Very! If you desire that lovely gooey texture, it’s important to underbake slightly. Start checking for doneness at the 20-minute mark; you’re looking for a toothpick to come out with a few moist crumbs—this ensures the cake will be velvety. If it turns out too dense, next time try folding in the cake mix gently to avoid overmixing, which can cause a firmer texture.
Are there any dietary considerations I should be aware of?
Absolutely! While this Chocolate Peanut Butter Dump Cake is indulgent, keep in mind the presence of peanuts which can trigger allergies in some individuals. If you’re cooking for guests, be sure to ask about food allergies. For pet owners, this dessert contains chocolate, which is toxic to dogs, so keep the leftovers out of their reach.
Can I make this cake ahead of time?
Yes, you can! Prepare the batter and store it in the fridge for up to 24 hours before baking. When you’re ready to bake, just pour it into your greased pan and pop it in the oven! This can save you time, especially during gatherings, letting you focus on enjoying your company while the cake bakes!
