Ingredients

  • ½ cup / 130g peanut butter smooth
  • 1 cup / 100g almond flour
  • ½ cup / 120g butter melted
  • 2 egg large
  • ½ cup / 90g granulated sweetener
  • 1 teaspoon baking powder
  • 1 teaspoon vanilla extract
  • ⅓ cup / 40g chocolate chips or chopped 90% dark chocolate, sugar free

Instructions

    Cup of Yum
  1. Preheat the oven to 180 C / 350 F and line a rectangular oven proof dish with parchment paper (Mine was 20 x 15 cm / 8 x 6 inch).
  2. Melt the butter and put all ingredients except for the chocolate chips in a bowl. Stir together with a fork. Then, stir through the chocolate chips, holding a few back to scatter over the top.
  3. Fill the batter into the oven proof dish and scatter the remaining chocolate chips over the top.
  4. Bake for 20 minutes or until lightly golden on top. The centre should still be soft and jiggly.
  5. Let cool fully before cutting.

Notes

  • Each blondie square contains about 3 grams net carbs when made with sugar-free chocolate chips.
  • If using 90% dark chocolate instead of sugar-free chips, net carbs reduce slightly to about 2.5 grams per serving.
  • Do not overbake; the blondies should remain jiggly in the middle when taken out of the oven.
  • Store in an airtight container at room temperature for up to 3 days or refrigerate for up to 1 week.
  • Freeze cooled blondies for up to 6 months to extend shelf life.
