These delicious and “healthy-ish” Peanut Butter Brownies will satisfy your dessert cravings and provide significant nutritional benefits to start your new year off right!

Peanut Butter Brownies

Flavorful, moist and visually striking, these brownies are a joy to eat and made from a list of ingredients that pack a nutritional punch, including dark chocolate (for antioxidants), whole wheat flour (for a boost of fiber for gut health and satiety) and Heinen’s freshly ground peanut butter (for a minimally processed dose of plant-based protein).

If you are looking to reduce your sugar intake this year, Swerve brown sugar substitute and Swerve powdered sugar substitute can be easily swapped for regular sugars.

Let’s bake!

Peanut Butter Brownies

Peanut Butter Brownies


For the Brownie Batter

  • ½ cup (1 stick) butter
  • 3 oz. Heinen's dark chocolate chips
  • ¾ cup Swerve brown sugar substitute or Heinen’s light brown sugar
  • 2 eggs
  • 2/3 cup whole wheat flour
  • Dash of salt
  • 1 Tbsp. Heinen’s almond milk

For the Peanut Butter Swirl Topping

  • 2 Tbsp. butter
  • ½ cup Heinen’s freshly ground peanut butter
  • ¼ cup Swerve powdered sugar substitute or regular powdered sugar
  • ¼ cup Heinen’s dark chocolate chips


  1. Preheat the oven to 350˚F. Line an 8×8-inch baking pan with parchment paper or foil. Grease with butter and set aside.
  2. Prepare the brownie batter. In a large microwave-safe bowl, combine ½ cup butter and 3 oz. dark chocolate. Microwave for 1-2 minutes until melted, checking frequently after 1 minute to avoid over-microwaving.
  3. Stir in the brown sugar and add the eggs, one at a time, stirring after each addition.
  4. Add the whole wheat flour and salt and stir to combine.
  5. Add the almond milk and stir to combine.
  6. Prepare the peanut butter swirl. In a small microwave-safe bowl, microwave 2 Tbsp. butter for 30 seconds to 1 minute, or until melted. Add the powdered sugar and peanut butter and stir thoroughly to combine.
  7. Pour the brownie batter into the prepared pan and spread with a spatula to flatten. The batter will be thick.
  8. Add spoonfuls of the peanut butter swirl on top of the brownie batter. Using a knife, swirl the peanut butter and brownie batter together.
  9. Sprinkle dark chocolate chips on top.
  10. Bake for 30 minutes, or until the brownie batter is set. The peanut butter swirl will look slightly wet, but it will solidify as the brownies cool.
  11. Let cool in the pan for 10 minutes, then finish cooling in the refrigerator for at least one hour.
  12. Cut into squares with a sharp knife and serve.
