Tips for Perfect Blueberry Lemon Protein Bars
- Use fresh lemon zest for the brightest flavor.
- If using frozen blueberries, don’t thaw them to avoid extra moisture.
- Toss blueberries in a little gluten-free flour so they don’t sink to the bottom of the pan when baking.
- Choose a protein powder you enjoy, as it affects the flavor. Our favorite CLEAN protein powders are from Just Ingredients, especially the Vanilla Protein! (Use this link for 10% off sitewide!)
- Let the bars cool fully for the best texture and easy slicing.

Simple Swaps for Extra Flavor
Protein Powder: Swap Vanilla protein powder for a lemon or blueberry protein powder for extra flavor!
Milk: Use any plant-based milk like oat, coconut, or cashew milk instead of almond milk. Regular milk also works here if you don’t have a dairy allergy.
Berries: Swap out the blueberries for raspberries or even blackberries if you’d like!

Gluten-Free Blueberry Lemon Protein Breakfast Bars
Ingredients
- 2 cups gluten-free rolled oats
- 2 cups protein powder (we like to use Just Ingredients Vanilla)
- 2 tsp baking powder
- 1 tsp salt
- 1 cup almond milk
- 1/2 cup honey
- 1/2 cup fresh lemon juice
- 2 tsp vanilla extract
- 2 tbsp fresh lemon zest
- 2 cups fresh or frozen blueberries (see note)
Optional Icing:
- 1/2 tbsp lemon juice
- 1/2 cup powdered sugar
Instructions
- Preheat oven to 350°F and grease or line a 13" x 9" baking pan with parchment paper.
- In a large mixing bowl combine the dry ingredients: oats, protein powder, baking powder, and salt. In a medium sized mixing bowl, whisk the wet ingredients: almond milk, honey, lemon juice, vanilla, and lemon zest. Whisk well until fully combined. Next, fold in the blueberries careful not to crush or pop them.
- Pour the wet ingredients into the dry ingredients. Mix well until fully combined. Then, pour into your prepared baking dish and spread evenly.
- Bake for about 35 minutes or until a toothpick comes out clean and edges are golden brown. Allow the bars to cool in the pan on a wire rack before cutting into bars. Drizzle with icing, if using.
- Optional icing: In a small bowl, combine the powdered sugar and lemon juice. Mix well to combine. Add more powdered sugar to thicken or lemon juice to thin to your desired consistency.
