Step-by-Step Instructions

Grease your glass baking dish and set oven to the right temperature to make sure your cake cooks evenly and does not stick

Mix the Chocolate Cake Layer:

Make the Peanut Butter Cream Swirl:

Beat softened cream cheese and melted butter together until they look airy and lump free so the swirl is easy to spoon over the cake

Add Peanut Butter and Vanilla:

Blend in peanut butter and vanilla until there is no streak and the mix is glossy and thick

Add Powdered Sugar Gradually:

Add powdered sugar one cup at a time to get a thick almost frosting like cream that holds its shape on the cake do not rush this step

Swirl Peanut Butter Cream on Cake:

Dollop large spoonfuls of the peanut butter cream over the cake batter in your pan spacing them for the best marbled look try not to stir or mix in

Top with Chocolates:

Sprinkle chocolate chips and halved peanut butter cups over everything pressing them into the batter gently so some are visible after baking

Bake:

Bake in the oven for forty five to fifty five minutes until the top is set edges puffed and the center gives just a little when jiggled for perfect gooeyness

Cool and Serve:

Allow cake to cool slightly before serving for gooey slices or let it chill for easier cutting and serving at gatherings

Save

Reese’s cups have always been my favorite candy and there is nothing better than pulling this cake from the oven and seeing those pools of peanut butter start to melt over the hot chocolate cake. My kids love to sneak the Reese’s halves before the cake is baked so I always hide a few for the top just before it goes in the oven.

Storage Tips

Store cooled cake covered at room temperature if eating within twenty four hours or in the fridge for up to five days. For longer storage freeze cut pieces tightly wrapped. Thaw at room temperature or microwave for soft gooey results like day one.

Ingredient Substitutions

You can swap creamy almond butter or sunflower seed butter for peanut butter if needed but make sure it is not too runny. Regular chocolate chips can be traded for dark chips or even white. If you are out of mini Reese’s peanut butter cups use chopped full size cups or add extra chips.

Serving Suggestions

This cake is perfect served slightly warm in big squares with a scoop of vanilla ice cream. For special occasions drizzle with extra melted chocolate or peanut butter just before serving. It travels well for potlucks and bake sales and always disappears fast.

Recipe FAQs

→ How do I achieve the perfect peanut butter swirl?

Drop spoonfuls of the peanut butter cream mixture onto the chocolate cake batter without blending completely; this lets the swirl develop as the cake bakes and forms its signature cracks.

→ Can I substitute the chocolate cake mix?

Yes, any preferred chocolate cake mix or homemade batter will work; just follow the mix's instructions for best consistency.

→ How can I ensure gooey, moist texture?

Avoid overbaking and let the center remain slightly wobbly. Cooling allows it to set while staying deliciously soft inside.

→ Are there tips for slicing clean portions?

Let the cake cool, then refrigerate for about an hour. This firms it up, making it easier to slice into neat squares.

→ Can I add more peanut butter flavor?

Swirl a little melted peanut butter on top before baking, or add extra peanut butter cups for even more flavor punch.

→ What pan is best for baking?

A glass baking dish promotes even heat and consistent results. Metal pans are fine; just check for doneness a few minutes earlier.
