Part 3: Step-by-Step Instructions
Preparing the Cake Base
Start by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking dish with nonstick spray or line it with parchment paper for easy removal.
In a medium bowl, mix together a chocolate cake mix, 1/2 cup of melted butter, and a large egg until the mixture is combined and thick. Press this dough evenly into the bottom of the prepared pan to form a firm base layer. The texture should be dense, almost like a brownie batter.
For an extra touch of decadence, consider mixing some dark chocolate chips into the batter. This adds a rich chocolate flavor that pairs perfectly with the gooey filling.
Creating the Gooey Peanut Butter Layer
In a separate bowl, beat an 8-ounce package of cream cheese (softened) together with 2 cups of creamy peanut butter until the mixture is smooth. Gradually add in 2 cups of powdered sugar, 1/2 cup of melted butter, 3 large eggs, and a teaspoon of vanilla extract. Continue blending until the filling is creamy and well incorporated.
Pour this peanut butter mixture over the chocolate base, spreading it out evenly with a spatula. Make sure to cover the entire surface to achieve a uniform layer of gooey goodness.
Baking Tips for the Perfect Gooey Texture
Place the baking dish in the oven and bake for 40-45 minutes. Look for edges that are set and golden brown while the center remains slightly jiggly. This ensures the characteristic gooey texture without overbaking.
Avoid leaving it in the oven for too long, as this can result in a drier cake. For the ideal bake, the center should still move a bit when the pan is gently shaken.
Letting It Cool Before Slicing
Allow the cake to cool in the pan for at least 30 minutes before slicing. This gives the gooey center time to set up just enough while still maintaining that soft, melt-in-your-mouth texture.
