This blondie inspired peanut butter slice is made with sugar-free sweetener and low-carb flours for a healthy, keto-friendly and gluten-free dessert or a snack.

Ingredients 

  • 1 cup peanut butter crunchy, unsweetened
  • 1/4 cup coconut oil measured in slightly softened solid form
  • 1/2 cup Sukrin Gold brown sugar alternative see notes for substitutes
  • 3 eggs
  • 1.5 tablespoons vanilla
  • 2/3 cup almond meal/flour (100 g)
  • 2 tablespoons coconut flour
  • A pinch of salt
  • 1 teaspoon baking powder gluten-free
  • 2 squares 90% Lindt chocolate broken into pieces or dark chocolate buttons

Instructions

  • Preheat the oven to 180 C / 355 F.
  • Melt peanut butter and coconut oil (you can do this in a hot oven, microwave or over low heat on the stove). Transfer to a large mixing bowl, add the brown sugar alternative and combine with a spatula.
  • Add eggs and vanilla and whisk together.
  • Add the flours, salt and baking powder and mix through.
  • Transfer to a baking tin (10.5 x 8-inch) lined with parchment paper. Flatten the top with a spatula. Insert a few pieces of dark chocolate or chocolate buttons. You can also melt the dark chocolate first and drizzle it over the top, then use a knife or a skewer to swirl it through the batter.
  • Bake for 20 minutes until just set. Remove from the oven and cool for 10 minutes before removing from the tray. Slice into even squares.

Notes

Sugar-alternatives:  In this recipe, I am using Surkin Gold, which is a low-cal, low-carb brown sugar alternative. It has a similar texture, aroma and taste to light brown sugar but is in fact a mix of erythritol, which is made from fermented glucose extracted from non-GM corn starch, stevia, and gluten-free malt. You can use regular white sugar-alternative powder (I prefer erythritol and stevia mix for the least aftertaste). Alternatively, coconut sugar would also work well as a low-GI sugar substitute.
Storing: Store for 4-5 days in an airtight container or for 7-8 days in the refrigerator.
Freezing: This peanut butter blondie slice can also be frozen for up to 3 months. Slice it first and store in Ziploc bag or container with a lid. Defrost overnight and reheat in the oven or microwave slightly before consuming.
