Chocolate Peanut Butter Ooey Gooey Cake Ingredients
For the Cake
- Chocolate Cake Mix – A fantastic base that delivers rich flavor; using a homemade mix can elevate the taste even further.
For the Peanut Butter Filling
- Creamy Peanut Butter – Adds a luscious richness; swap in crunchy peanut butter if you love an extra texture.
- Cream Cheese (8 oz, softened) – This thickens the filling beautifully, giving it that creamy texture; mascarpone or thick Greek yogurt works as great substitutes.
- Powdered Sugar (2 cups) – Sweetens and provides structure; adjust to your preference if you like a less sweet filling.
For the Ganache
- Heavy Cream (1 cup) – The key to a silky-smooth ganache; reduce the amount slightly for a lighter topping.
- Dark Chocolate (8 oz, chopped) – Gives a rich, deep flavor; substituting with milk chocolate will provide a sweeter note.
For Garnish
- Crushed Peanuts (½ cup) – A delightful topping that adds crunch and complements the peanut butter; try almonds or toffee bits for something new.
- Optional Candy Garnish – Elevate your dessert with chocolate bars or peanut butter cups for an indulgent touch.

Step‑by‑Step Instructions for Heavenly Chocolate Peanut Butter Ooey Gooey Cake
Step 1: Prepare the Cake
Preheat your oven to 350°F (175°C). In two 8-inch round pans, prepare your chocolate cake mix according to the package instructions, then pour the batter evenly. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Once baked, allow the cakes to cool completely in the pans for about 15 minutes before transferring them to a wire rack.
Step 2: Make the Peanut Butter Filling
In a mixing bowl, beat 8 oz of softened cream cheese until smooth and creamy, about 2 minutes. Gradually incorporate the creamy peanut butter and 2 cups of powdered sugar, mixing on low speed to avoid a powdered sugar cloud. Continue to mix until everything is well blended and fluffy, giving a rich, decadent filling for your Chocolate Peanut Butter Ooey Gooey Cake.
Step 3: Assemble the Cake
Start by placing one layer of the cooled chocolate cake on a serving plate. Generously spread a thick layer of the peanut butter filling over the first cake layer, smoothing it out evenly. Carefully top it with the second layer of cake, pressing gently to secure it in place. Your scrumptious dessert is now set for the finishing touches!
Step 4: Prepare the Chocolate Ganache
In a small saucepan, heat 1 cup of heavy cream over medium heat until it reaches a simmer, stirring occasionally. Once simmering, remove the cream from heat and add 8 oz of chopped dark chocolate. Allow the mixture to sit for 5 minutes before stirring it gently until it transforms into a smooth and glossy ganache, perfect for draping over your cake.
Step 5: Top the Cake
With the ganache ready, pour it generously over the cake, allowing it to cascade down the sides for a luscious look. Use a spatula to smooth out the top and make sure the ganache is evenly distributed, covering the cake beautifully while showcasing the rich Chocolate Peanut Butter Ooey Gooey Cake underneath.
Step 6: Garnish
To add a delightful crunch and visual appeal, sprinkle ½ cup of crushed peanuts over the top of the ganache. Feel free to get creative by adding optional candy garnishes, like chocolate bars or peanut butter cups, making your cake not just delicious but also irresistible and fun to serve.
Step 7: Chill and Serve
Refrigerate the assembled cake for at least 1 hour to let the layers set and the flavors meld beautifully. When ready to serve, slice your decadent Chocolate Peanut Butter Ooey Gooey Cake and witness the joyous reactions as you share this indulgent treat with friends and family!

Chocolate Peanut Butter Ooey Gooey Cake Recipe FAQs
How do I choose the right chocolate cake mix for this recipe?

What’s the best way to store leftover cake?
To keep your cake fresh, place it in an airtight container or tightly cover it with plastic wrap. It will last in the fridge for up to 3 days. If you have more than enough leftovers, consider freezing it to enjoy later!

What should I do if my peanut butter filling is too runny?
