Peanut Butter Nutella Swirl Brownies Recipe

Prep Time15 minutes
Cook Time35 minutes
Total Time50 minutes

Ingredients

  • Unsalted butter – melted because we’re lazy and proud
  • Granulated sugar – sweetness + shiny brownie tops
  • Brown sugar – adds moisture and depth aka flavor glow-up
  • Eggs – room temperature if you remember cold if you don’t
  • Vanilla extract – optional but emotionally necessary
  • All-purpose flour – just enough to hold things together
  • Unsweetened cocoa powder – the chocolate backbone
  • Salt – trust me it makes everything better
  • Creamy peanut butter – smooth works best for swirling
  • Nutella – obviously the star of the show

Instructions

  • Preheat your oven to 350°F (175°C) and line an 8x8-inch pan with parchment paper. Skip this step and you’ll regret it later.
  • Mix melted butter and sugars in a large bowl until glossy and smooth. This is where that crinkly brownie top magic begins.
  • Add eggs and vanilla, whisking until fully combined. The batter should look thick and luxurious—like it knows it’s about to be amazing.
  • Stir in cocoa powder, flour, and salt just until combined. Don’t overmix unless dry, tough brownies are your thing (no judgment… okay, a little).
  • Pour the batter into the pan, spreading it evenly. Drop spoonfuls of peanut butter and Nutella all over the top like you’re feeling chaotic—in a good way.
  • Swirl gently with a knife or skewer. Fewer swirls = prettier contrast. More swirls = chaos brownies. Both are valid.
  • Bake for 30–35 minutes, until the edges are set and the center still looks slightly underdone. That’s how you get fudgy brownies, not brownie-flavored bricks.
  • Cool completely (or mostly… we’re not strict here) before slicing.
