Description

A rich, moist, and decadent chocolate cake featuring swirls of creamy peanut butter and chunks of Reese’s cups. This one-bowl dessert offers a perfect salty-sweet balance and is surprisingly easy to make.

Ingredients

Scale

1 ½ cups all-purpose flour
½ cup unsweetened cocoa powder
1 cup granulated sugar
1 tsp baking powder
½ tsp salt
½ cup vegetable oil
2 large eggs
½ cup heavy cream
1 tsp vanilla extract
½ cup creamy salted peanut butter
4–5 Reese’s Peanut Butter Cups (chopped)
Flaky sea salt (for topping)

Instructions

Preheat oven to 350°F (175°C). Grease a 9×9 inch baking pan, line with parchment paper, and grease the paper.
In a large bowl, whisk together flour, cocoa powder, sugar, baking powder, and salt until uniform.
Add eggs, vegetable oil, heavy cream, and vanilla extract to the dry ingredients. Whisk vigorously for 2 minutes until the batter is thick and glossy.
Gently fold in the remaining flour mixture until just combined, being careful not to overmix.
Fold in half of the chopped Reese’s cups into the batter.
Drop spoonfuls of creamy peanut butter over the batter and swirl with a knife or offset spatula to create marble patterns.
Scatter the remaining chopped Reese’s cups on top.
Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with moist crumbs.
Let cool for 10 minutes, then sprinkle with flaky sea salt before serving.

Notes

Do not overbake; the center should be slightly gooey. Use creamy salted peanut butter for the swirls to prevent sinking. Cold heavy cream helps create a lighter texture. Store in an airtight container for up to 5 days in the fridge or freeze for up to 3 months.
