Method
- Preheat your oven to 350°F (175°C). Line an 8x8 inch baking dish with parchment paper, leaving some overhang on the sides to easily lift the bars out later.
- In a medium bowl, whisk together the almond flour, whey protein powder, erythritol (or sweetener of choice), and a pinch of salt. Ensure there are no clumps of protein powder.1 cup almond flour, 1/2 cup whey protein powder, 1/4 cup erythritol or your preferred keto-friendly sweetener, Pinch salt
- In a separate small bowl, whisk together the melted butter, large egg, vanilla extract, lemon zest, and fresh lemon juice.1/4 cup unsalted butter, 1 large egg, 1 teaspoon vanilla extract, 1 teaspoon lemon zest, 2 tablespoons fresh lemon juice
- Pour the wet ingredients into the bowl with the dry ingredients. Mix with a spatula or wooden spoon until just combined and a thick dough forms. Be careful not to overmix.
- Spoon the dough into the prepared baking dish. Use your spatula or your hands (lightly dampened if sticky) to press the dough evenly into the bottom of the dish, creating a smooth, compact layer.
- Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the edges are lightly golden and the center is set. A toothpick inserted into the center should come out mostly clean.
- Remove the baking dish from the oven and let the bars cool completely in the dish on a wire rack. Once cooled, use the parchment paper overhang to lift the entire slab out of the dish. Place it on a cutting board and slice into your desired bar shapes.
