If you're craving something fresh and energizing, these homemade lemon protein bars are it! Made with oats, coconut, chia seeds, almond butter, and a pop of lemon zest, they’re the perfect grab-and-go snack for warm days.

No baking required, just toss everything in the food processor. Each bar delivers 17 grams of protein and major citrusy flavor. Keep them in the fridge for a refreshing bite anytime.

Why you'll love Homemade Protein Bars

  • Bright lemon flavor with no baking required

  • 17 grams of protein in every bar

  • Made with simple to find, wholesome ingredients

Lemon Protein Bar Ingredients

  • Protein Powder: I used a whey protein powder, any variety will do, just use your favorite. Keep in mind the protein content of your bars may vary depending on the protein powder you use.
  • Rolled Oats: also known as Old Fashioned Oats
  • Shredded Coconut: sweetened or unsweetened flakes, personal preference.
  • Coconut Oil: helps the bars hold together well.
  • Almond Butter: can be subbed with any other nut butter such as cashew, sunflower or peanut butter, although cashew and almond pair best with the lemon.
  • Honey: can be subbed for any liquid sweetener.
  • Chia Seeds: adds fiber, but you can skip if you prefer. 
  • Lemon: Lemon zest and juice
  • White Chocolate: this is an optional ingredient. I love them with and without it.

How to Make Lemon Protein Bars

  1. Pulse dry ingredients- In a 7 cup or larger food processor fitted with a steel S blade, add the protein powder, rolled oats. Blend for 1 minute, until oats are powdery and fine, as pictured above.
  2. Add remaining ingredients- Add coconut flakes, chia seeds, lemon zest, lemon juice, melted coconut oil, almond butter, and honey to the food processor. Blend for another 30 seconds, or until mixture is well combined.
  3. Check consistency- Fold some of the mixture in your hand; it should form a ball and not crumble. If the mixture is crumbly, add water and process again.
  4. Press & chill- Line a 9 x 5 inch loaf pan with parchment, and press the protein bar mixture into the pan until smooth across the top. Chen chill for 2 hours (or freeze for 30 minutes).
  5. Optional drizzle- you can drizzle melted white chocolate and extra lemon zest over the top if desired.

Storage + Reheating

These bars hold up beautifully in both the fridge and freezer.

  • Fridge: Store in an airtight container for up to 7 days. Because of the coconut oil, they’re best kept cold—avoid leaving them at room temperature for long.
  • Freezer: Wrap each bar in parchment paper and place in a freezer-safe bag or container. They’ll stay fresh for up to 3 months.
