Keto and vegan peanut butter blondies, made with only 4 ingredients! Oil-free, flourless, and grain-free, they have 125 calories each, and can be made paleo-friendly with almond butter.



  • 1/4 cup (60 mL) water
  • 4 and 1/2 teaspoons (9.75 g) flaxseed meal
  • 1 and 1/4 cups (330 g) creamy unsweetened peanut butter
  • 3/4 cup (145 g) keto-friendly brown sugar equivalent (for testing, I used sukrin gold)
  • 1/2 teaspoon baking soda


  1. Preheat oven to 350F (175C). Line a 9-inch (22.5 cm) baking pan with foil or parchment paper; spray exposed interior sides with cooking spray.
  2. In a small cup or dish, combine the water and flaxseed meal. Let stand 5 minutes to thicken.
  3. In a medium bowl, whisk water-flax mixture, peanut butter, sugar substitute, and baking soda until completely blended and smooth. The batter will be quite stiff.
  4. Scrape into prepared pan, smoothing the top (it will be very thick, so use your fingertips to press down).
  5. Bake in the preheated oven for 30 to 35 minutes until deep golden brown, surface appears dry and center looks just set (they will get firm as they cool).
  6. Cool completely in pan on a wire rack.
  7. Remove blondies from pan and cut into 16 squares.


Storage: Store the cooled blondies in an airtight container at room temperature for 1 day, the refrigerator for 1 week, or the freezer for up to 6 months.
Tip: An equal amount of ground chia seeds can be used in place of the flaxseed meal.
