Ingredient Notes and Substitutions

Customize your blondies with these smart swaps.

  • Almond Flour: You can substitute with an equal amount of finely ground almond meal for a slightly coarser texture. Coconut flour can be used but requires a different ratio (start with 1/2 cup and adjust liquid).
  • Swerve Sweetener: Any granular keto-friendly sweetener like erythritol, monk fruit sweetener, or xylitol (if not serving to pets) can replace Swerve. For the glaze, use powdered versions of these sweeteners.
  • Butter: Ghee or a dairy-free butter substitute can be used if needed. Ensure it’s unsalted.
  • Strawberries: If using frozen strawberries, thaw them completely and pat them very dry with paper towels before chopping to avoid excess moisture.

How to Make Keto Strawberry Lemon Blondies

  1. Preheat your oven to 325ºF (160ºC). Line a 9×9 inch metal baking pan with parchment paper. Ensure the paper has overhang on the sides for easy lifting later.
  2. In a large bowl, whisk together the almond flour, granulated Swerve sweetener, baking powder, and salt. Make sure there are no clumps.
  3. Add the melted butter, large egg, egg yolk, lemon zest, lemon juice, and vanilla extract to the dry ingredients. Stir everything together until a cohesive dough forms.
  4. Gently fold the finely chopped strawberries into the dough. Be careful not to overmix.
  5. Transfer the thick dough to the prepared baking pan. Use a spatula or your hands, lightly dampened, to press the dough evenly into the pan. This step requires some effort due to the dough’s thickness.
  6. Bake for 30 to 35 minutes. The edges should be golden brown, and the top should look set and feel firm to the touch. It might seem slightly soft but should not appear wet.
  7. Let the blondies cool completely in the pan on a wire rack. This is crucial for them to set properly.
  8. Begin the glaze: In a blender or food processor, combine the 2 medium strawberries and 1 tablespoon of lemon juice. Blend until smooth.
  9. Pour the strawberry puree into a small bowl. Whisk in 1/2 cup of the powdered Swerve sweetener until the glaze is smooth. If it seems too thin, gradually add more powdered sweetener until you achieve a nice drizzling consistency.
  10. Once the blondies are completely cool, drizzle the strawberry glaze evenly over the top. Spread it out with a spatula if needed.
  11. Refrigerate the blondies for at least 30 minutes. This helps the glaze set firmly, making the bars easier to cut.
  12. Use the parchment paper overhang to lift the entire slab of blondies out of the pan. Cut into 12 bars.

Pro Tips for Perfect Results

  • Control cooking time carefully: Overbaking will make keto blondies dry. Look for the edges to be golden and the center to be set but not wet.
  • Adjust seasoning to taste: Taste your dough before baking (if comfortable with raw eggs) to adjust sweetness or lemon.
  • Use fresh ingredients when possible: Fresh lemon zest and juice provide the best bright flavor.

Common Mistakes to Avoid

  • Overmixing the dough: This can lead to tough blondies. Mix just until combined.
  • Cutting while warm: Allowing the blondies to cool completely before cutting ensures clean slices. The glaze also needs time to set.

Variations

  • Add other berries: Mix in raspberries or blueberries along with or instead of strawberries.
  • Add white chocolate chips: Sugar-free white chocolate chips offer a delicious contrast.

Serving Suggestions

  • Enjoy these blondies plain as a satisfying dessert.
  • Serve with a dollop of sugar-free whipped cream or a scoop of keto ice cream.
