Protein Power: The cashews and almonds in these bars are not just for crunch; they add natural protein that helps keep your muscles strong and keeps you feeling full longer. Whether you are active or just have a busy day, these bars are a great boost.

Healthy Fats: Nuts and coconut oil add healthy fats that your body needs. These fats are good for keeping your energy levels up throughout the day without a crash.

Natural Sweeteners: I like to use maple syrup to sweeten these bars, which is a much better option than refined sugar. It is not just about lowering calories; it is about choosing a sweeter option that is better for your overall health.

Lactose-Free and Gluten-Free: These bars do not contain dairy or gluten, making them a fantastic snack option for almost anyone. They are easy to whip up, and you do not have to worry about possible tummy problems.

  • 3 tablespoons (45 ml) coconut oil

  • 1/4 teaspoon (1.5 grams) salt

  • Lemon Zest and Juice: Use fresh lemons for zesting and juicing to maximize the vibrant citrus flavor in the bars. Ensure the lemons are thoroughly washed if they’re waxed or treated.
  • Use Parchment Paper: Line your pan with parchment paper with overhanging edges to make it easier to lift the entire set of bars out of the pan once they are firm. This makes cutting much easier and less messy.
  • Adjust Sweetness and Tartness: Depending on your taste preferences, you can adjust the amount of lemon juice and maple syrup. Add more syrup for sweetness or more lemon juice for tartness. Taste the mixture before setting it to ensure it meets your preference.
  • Pre-soak the Cashews: For a smoother filling, soak the cashews overnight in cold water or for at least 4 hours. This softens them, making them easier to blend into a creamy consistency without overworking your blender.
  • Customize Your Base: If you prefer a different texture or flavor, you can substitute almonds with other nuts like pecans or walnuts for the crust. Each offers a unique taste and consistency.
  • Nutritional Boost: For an added nutritional boost, sprinkle some chia seeds or flaxseeds into the crust mixture or the filling.
  • Storage: Store these bars in an airtight container in the refrigerator for up to a week or in the freezer for up to a month. The flavor often enhances slightly after the bars have been chilled for a day.
