Step‑by‑Step Instructions for 1 Bowl Peanut Butter Cup Dump Cake Delight Devours Time
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While it warms, take a 9×13-inch baking dish and generously grease it with butter or non-stick spray to ensure your cake releases easily once baked.
Step 2: Spread the Peanut Butter
Once the oven reaches temperature, take your room-temperature peanut butter and spread it evenly across the bottom of the prepared baking dish. This will create a luscious, gooey layer that complements the cake’s fudgy texture beautifully.
Step 3: Mix the Batter
In a large mixing bowl, combine the cake mix, melted butter (remember to let it cool slightly), and milk. Whisk everything together until smooth, leaving just a few small lumps for that perfect fudgy consistency in the one bowl peanut butter cup dump cake delight.
Step 4: Pour and Spread
Next, pour the batter over the peanut butter layer that you just spread. Use a spatula to gently spread the batter evenly, ensuring that every inch of the peanut butter layer is covered, ready to create the magic as it bakes.
Step 5: Add Toppings
Now, sprinkle mini peanut butter cups and chocolate chips generously over the top of the batter. This step adds delightful bursts of flavor throughout your cake, making each bite of the 1 bowl peanut butter cup dump cake delight a heavenly experience.
Step 6: Bake
Place the baking dish in the preheated oven and let it bake for 35-40 minutes. You’ll know it’s ready when the edges pull away from the sides of the pan and a toothpick inserted into the center comes out with moist crumbs rather than wet batter.
Step 7: Cool Before Serving
Once baked, remove the cake from the oven and allow it to cool for at least 15 minutes. This cooling time not only helps the layers set beautifully but also enhances the cake’s rich flavors, making it even more delicious when you’re ready to serve.

Make Ahead Options
These 5-Ingredient Peanut Butter Cup Dump Cake Delights are perfect for meal prep enthusiasts! You can prepare the peanut butter layer and mix the cake batter up to 24 hours in advance. Simply spread the peanut butter at the bottom of the greased baking dish, and mix the cake ingredients in a bowl before refrigerating them separately. When you’re ready to bake, pour the batter over the peanut butter layer, add your toppings, and pop it in the oven. This way, you can enjoy a homemade dessert with minimal effort on busy nights—a delicious treat that stays just as fudgy and flavorful!

1 Bowl Peanut Butter Cup Dump Cake Delight Recipe FAQs
How should I choose the right peanut butter?
Absolutely! For best results, choose a creamy, natural peanut butter that’s easy to spread. If you’re using a jar that’s been sitting, letting it sit at room temperature for a while will make it much easier to work with. Look for ones with minimal ingredients—just peanuts and maybe a little salt—so you get a purer flavor without added sugars or oils.
How should I store the peanut butter cup dump cake?
You can keep your peanut butter cup dump cake in an airtight container at room temperature for up to 3 days. If you find it will be longer than that before it’s finished, you can refrigerate it for up to a week. Just make sure it’s wrapped well so it doesn’t dry out!
Can I freeze leftover dump cake?
Yes, indeed! For freezing, wrap individual slices in plastic wrap followed by aluminum foil, or place the whole cake in a tightly sealed container. It can be kept in the freezer for up to 2 months.

What if my cake batter is too thick?
If your batter seems too thick, no problem! Just add a little more milk, one tablespoon at a time, until you reach the desired pourable consistency. Remember, a few lumps are perfectly fine—they contribute to that delectable fudgy texture that you’re aiming for!
Is this dessert safe for kids with nut allergies?
