Ingredients

Scale
  • 2 large eggs, room temperature
  • 3/4 cup (171g) unrefined cane sugar or white granulated sugar
  • 1 cup (190g) chocolate chips
  • 1/3 cup (74g) plant-based butter
  • 1/2 tsp instant coffee granules or espresso powder (optional)
  • 1 tsp vanilla extract
  • 1/2 tsp salt
  • 1/2 tsp baking powder
  • 1/4 cup (20g) Dutched cocoa powder
  • 3/4 cup + 2 Tbsp (114g) all-purpose flour
  • 1/4 cup (64g) runny, natural peanut butter

Instructions

  1. Bring eggs to room temperature by soaking in warm water for 10 minutes.
  2. In a stand mixer, beat the eggs and sugar on medium-high until light and foamy (about 3–5 minutes).
  3. Meanwhile, melt chocolate chips and butter in the microwave in 30-second intervals, stirring between each until smooth. Stir in coffee powder if using. Let cool for 5 minutes.
  4. Stir vanilla into the egg/sugar mixture. Fold in the slightly cooled chocolate mixture until combined.
  5. Add salt and baking powder. Sift in the cocoa powder and flour. Gently stir to combine.
  6. Let dough rest at room temperature for 30 minutes to firm up.
  7. Preheat oven to 350°F and line baking sheets with parchment paper.
  8. Scoop cookie dough (1.5 Tbsp size) onto baking sheets, 8 per tray.
  9. Use a 1/2 tsp to drizzle peanut butter over each dough ball. Swirl with a chopstick into “C” and “S” shapes.
  10. Bake for 5–6 minutes or until the centers appear slightly underbaked.
  11. Let cookies cool on the tray for 2 minutes, then transfer to a rack. Repeat as needed.
  12. Store in a single layer in an airtight container at room temperature.

Notes

  • Use natural, runny peanut butter at room temperature for best swirl results.
  • Don’t over-swirl the peanut butter to maintain distinct pools and visual appeal.
  • Pull cookies from the oven slightly underbaked for fudgy centers.
  • Instant coffee deepens chocolate flavor but is optional.
  • Let the dough rest to achieve scoopable consistency.
