Ingredients

For the crust:

2 tablespoons coconut flour
2 tablespoons butter, melted
2 tablespoons honey or maple syrup
1 teaspoon vanilla extract

For the filling:

2 tablespoons coconut flour
A pinch of salt

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

Prepare the crust: Preheat your oven to 350°F (175°C). In a medium-sized bowl, combine the almond flour, coconut flour, melted butter, honey (or maple syrup), and vanilla extract. Stir until everything is well combined and a dough forms. Press the mixture into the bottom of an 8×8-inch baking dish lined with parchment paper. Bake for 8-10 minutes or until the crust is golden and firm. Remove from the oven and let it cool while you prepare the filling.
Make the filling: In a separate bowl, whisk together the eggs, lemon juice, lemon zest, honey (or maple syrup), protein powder, coconut flour, and salt. Mix until smooth and well combined.
Assemble the bars: Pour the lemon filling over the cooled crust. Bake the bars in the preheated oven for 15-18 minutes, or until the filling is set and lightly golden around the edges. You can check for doneness by gently shaking the pan—if the center is firm, it’s ready.
Cool and chill: Let the bars cool in the pan for about 10 minutes, then transfer to the fridge and chill for at least 2 hours, or until completely set.
Cut and serve: Once the bars have chilled and are set, cut them into squares. Serve chilled and enjoy!

Variations

Flavor Boost: Add a few drops of lemon extract or orange zest to enhance the citrus flavor.
Sweeteners: Use your preferred sweetener, such as stevia, monk fruit, or agave, if you want to lower the sugar content.

Storage/Reheating

Storage: Store the Protein Lemon Bars in an airtight container in the fridge for up to 5 days. They are best enjoyed cold.

FAQs

1. Can I use a different type of flour for the crust?

Yes, you can try using oat flour or a gluten-free all-purpose flour instead of almond flour or coconut flour, though the texture may differ slightly.

2. Can I use a different protein powder flavor?

Yes, you can use any flavor of protein powder, but vanilla works best for this recipe. Lemon-flavored protein powder would be an excellent addition if available.

3. Can I make this recipe vegan?

To make this recipe vegan, substitute the eggs with flax eggs (1 tablespoon flaxseed meal mixed with 3 tablespoons water per egg) and use a plant-based protein powder. Use maple syrup instead of honey.

4. Can I make these Protein Lemon Bars without a protein powder?

Yes, you can omit the protein powder if you prefer, but the texture and protein content will change. You may need to add a little extra coconut flour to compensate for the missing protein.

5. How do I know when the filling is set?

The filling is set when the edges are lightly golden and the center is firm to the touch. You can also check by gently shaking the pan—if the center doesn’t jiggle, it’s ready.

6. Can I freeze these bars?

Yes, you can freeze the bars for up to 2 months. Wrap them tightly in plastic wrap or place them in an airtight container before freezing. Thaw in the fridge before serving.

7. Can I add a topping to these bars?

Yes, you can top the bars with whipped cream, a dusting of powdered sugar, or additional lemon zest for extra flavor and decoration.

8. How can I make the bars sweeter?

To make the bars sweeter, simply add more honey or maple syrup to the filling or the crust. You can also use a sweeter protein powder.

9. Can I double this recipe?

Yes, you can double the recipe and bake it in a larger baking dish (9×13 inches). Just adjust the cooking time slightly, as it may take a bit longer to bake through.

10. What’s the best way to cut the bars?

Use a sharp knife to cut the bars after they’ve chilled and set in the fridge. For cleaner cuts, run the knife under warm water between each slice.
