These rich and fudgy Chocolate Peanut Butter Brownies combine deep cocoa and creamy peanut butter for a perfectly chewy, sweet, and salty treat you’ll crave.

  • Total Time: 45 minutes
  • Yield: 9 large or 16 small brownies 1x

Ingredients

Scale

Dry Ingredients

  • 1 cup all-purpose flour

  • ½ cup unsweetened cocoa powder

  • ¼ tsp salt

  • 1 tsp baking powder

Wet Ingredients

  • ½ cup unsalted butter (or coconut oil for vegan version)

  • 1 cup granulated sugar

  • 2 large eggs (or flax eggs for vegan)

  • 1 tsp vanilla extract

Peanut Butter Swirl

  • ⅓ cup creamy peanut butter (natural preferred)

Optional Add-ins

  • ½ cup dark chocolate chips

  • Pinch of flaky sea salt

Instructions

  • Preheat your oven to 350°F (175°C). Line an 8×8-inch pan with parchment paper.

  • Whisk flour, cocoa powder, salt, and baking powder in a medium bowl.

  • Melt butter and mix with sugar until smooth.

  • Add eggs and vanilla, whisk until shiny.

  • Stir in dry mixture until just combined. Don’t overmix.

  • Pour half the batter into the prepared pan.

  • Drop spoonfuls of peanut butter and swirl gently with a knife. Add remaining batter, then more peanut butter and swirl again.

  • Sprinkle chocolate chips or sea salt if using.

  • Bake 25–30 minutes or until the center is just set and edges pull away slightly.

 

  • Cool completely before slicing for clean edges.

Notes

  • For fudgier brownies, slightly underbake by 2–3 minutes.

  • To make it gluten-free, replace flour with almond flour.

  • For dairy-free, use coconut oil and dairy-free chocolate.

 

  • Store in an airtight container at room temperature for 3 days or refrigerate up to 1 week.
