How to make no-bake lemon protein bars

To begin, you’ll assemble the ingredients and prepare the mixture in a large bowl. No baking is required for these bars, making them a convenient and quick snack option.

MAKE THE MIXTURE

In a large mixing bowl, combine the oats, almond flour, protein powder, and lemon zest.In a separate microwave-safe bowl, combine lemon juice, honey or maple syrup, almond butter, vanilla extract, and salt. Microwave the mixture in 20-second intervals, stirring in between, until smooth and well combined. Pour the wet ingredients into the dry ingredients and mix until everything is evenly coated.

SHAPE AND CHILL

Line an 8×8 inch baking dish with parchment paper. Press the mixture firmly and evenly into the dish. Place the dish in the refrigerator for at least 1-2 hours, or until the bars are firm.

CUT AND STORE

Once firm, remove the bars from the dish and cut them into squares or bars. Store the bars in an airtight container in the refrigerator for up to a week. These no-bake lemon protein bars are now ready to enjoy as a nutritious snack anytime!

TIPS FOR MAKING NO-BAKE LEMON PROTEIN BARS

Following these tips will help you create delicious and perfectly textured no-bake lemon protein bars every time!

  1. Use fresh lemons for the best lemon flavor. Freshly squeezed lemon juice and zest will enhance the taste of the bars.
  2. Zest your lemons before juicing them. This makes the zesting process much easier and ensures you get the most zest from your lemons.
  3. Consider adding turmeric for color. While not traditional in lemon bars, a pinch of turmeric can enhance the vibrant yellow color of the bars and add some health benefits.
  4. Be patient when mixing the ingredients. Ensure that all ingredients are well combined to achieve a consistent texture throughout the bars.
  5. Chill the mixture thoroughly. Allowing the mixture to set in the refrigerator for at least 1-2 hours will help the bars firm up and hold their shape when cut.
  6. Slice the bars once they are completely chilled. Cutting the bars when they are cold will result in cleaner cuts and neater edges.
  7. Store the bars in an airtight container in the refrigerator. This will keep them fresh and maintain their texture for longer.

POPULAR SUBSTITUTIONS & ADDITIONS FOR NO-BAKE LEMON PROTEIN BARS

  • Experiment with different nuts. Instead of walnuts, try pecans, almonds, hazelnuts, or cashews to customize the flavor and texture of your bars.
  • Add a hint of spice with ground ginger. Incorporating about 1/4 teaspoon of ground ginger into the mixture can add a delightful zing to your bars.
  • Explore citrus variations. Substitute lime juice for lemon juice to create tangy key lime bars for a refreshing twist on the classic recipe.
  • Opt for gluten-free oats if needed. To make this a gluten-free lemon bar recipe, use certified gluten-free oats in the recipe to ensure the bars are suitable for those with dietary restrictions.
  • Add chia seeds. Adding 2 tablespoons of chia seeds adds some healthy omega-3 fats. 
  • Adjust the sweetener to your preference. Experiment with different sweeteners such as medjool dates, cane sugar, coconut sugar, date syrup, honey, or agave nectar in the filling to tailor the sweetness level and achieve refined sugar-free options if desired.
  • Melted coconut oil instead of almond butter. Coconut oil will solidify when chilled, helping to bind the ingredients together and giving the bars a subtle coconut flavor. Use an equal amount of melted coconut oil as you would almond butter in the recipe.
  • Coconut Flour: You can also use coconut flour as a substitute for almond flour in this recipe to make lemon coconut protein bars. However, it’s important to note that coconut flour is more absorbent than almond flour, so you’ll need to adjust the amount used. Start by using about 1/3 to 1/2 of the amount of coconut flour compared to almond flour called for in the recipe. For example, if the recipe calls for 1 cup of almond flour, you can start with 1/3 to 1/2 cup of coconut flour. You may also need to increase the amount of wet ingredients, such as lemon juice or water, to achieve the desired consistency of the mixture.
