  • ¾ cup150 gGranulated sugar
  • 3½ tbsp packed50 gBrown sugar
  • 2 large100 gEggsroom temperature
  • 1¼ tsp5 gVanilla extract

  • ½ cup130 gPeanut butter, no salt addedstirred smooth
  • 2½ tbsp20 gPowdered sugar
  • ¼ cup40 gDry-roasted peanuts, unsaltedroughly chopped
  • ½ tsp2 gCanola oil

Steps

  1. Heat the oven to 350°F (175°C). Brush an 8-inch square pan with the canola oil and line it with parchment, leaving an overhang.
  2. Melt the butter and let it cool for 5 minutes.
  3. Make the peanut butter swirl: in a small bowl, stir the peanut butter with the powdered sugar until smooth. If it is stiff, warm it for 10 seconds in the microwave. Set aside.
  4. Make the brownie batter: in a large bowl, whisk the melted butter with the granulated sugar and brown sugar. Whisk in the eggs and vanilla until glossy, about 1 minute.
  5. Sift the unsweetened cocoa powder and flour over the bowl, add the salt, and fold until just combined. Fold in the chocolate chips.
  6. Spread the brownie batter in the pan. Drop spoonfuls of the peanut butter swirl over the top, then drag a butter knife through to marble it.
  7. Scatter the chopped dry-roasted peanuts over the top and press them in lightly.
  8. Bake for 25 to 28 minutes, until the edges are set and a toothpick in the center comes out clean or with a few moist crumbs, not wet batter.
  9. Cool in the pan on a rack for at least 1 hour, then lift out with the parchment and cut into 12 bars.

Food safety: Don't taste raw dough or batter: raw flour and raw eggs can carry germs.
