  • 1 tablespoon cocoa powder for dusting
  • 1 tablespoon almond butter optional
  • pinch of instant coffee optional

Equipment

  • 1 Mixing bowl
  • 1 Whisk
  • 1 Spatula
  • 1 8x8 baking pan
  • 1 Parchment paper
  • 1 measuring cups
  • 1 Measuring spoons
  • 1 cooling rack

Method

  2. In a mixing bowl, whisk together the Greek yogurt, eggs, zero-sugar sweetener, and vanilla extract until smooth.
  3. Add the cocoa powder, oat flour or almond flour, protein powder, baking powder, and salt.
  4. Mix gently until a thick brownie batter forms. Do not overmix.
  5. Fold in the sugar-free chocolate chips.
  6. Spread the batter evenly into the prepared baking pan.
  7. Sprinkle extra sugar-free chocolate chips on top if using.
  8. Bake for 20 to 22 minutes, or until the edges look set and the center is still slightly fudgy.
  9. Let the brownies cool in the pan for at least 20 minutes before slicing.
  10. Cut into 9 brownies and serve.

Notes

Storage:
Store cooled brownies in an airtight container in the refrigerator for 4 to 5 days.
Reheating:
Enjoy chilled for the fudgiest texture, or microwave one brownie for 8 to 10 seconds if you want it slightly warm.
Freezing:
Freeze sliced brownies in a freezer-safe container for up to 2 months. Thaw in the refrigerator before serving.
Recipe Notes:
Do not overbake these brownies. They should look set around the edges but still slightly soft in the center so they stay fudgy after cooling.
Protein Note:
Protein will vary depending on the Greek yogurt, protein powder, and chocolate chips used.
