Preheat your oven to 350°F (175°C). Line a baking dish with parchment paper, leaving some overhang on the sides for easy removal.
Prepare Dry Ingredients:
In a large bowl, combine oats, protein powder, almond flour, flaxseed meal, and salt. Mix well.
Mix Wet Ingredients:
In another bowl, whisk together Greek yogurt, honey or maple syrup, almond butter, egg, and vanilla extract until smooth.
Combine Wet and Dry Ingredients:
Add the wet ingredients to the dry ingredients and mix until well combined.
Fold in Blueberries:
Gently fold in the blueberries, being careful not to crush them too much.
Transfer to Baking Dish:
Transfer the mixture to the prepared baking dish and spread it evenly.
Bake:
Bake in the preheated oven for 20-25 minutes or until the edges are golden brown and a toothpick inserted into the center comes out clean.
Cool and Cut:
Allow the bars to cool in the baking dish for about 10 minutes, then use the parchment paper overhang to lift them out. Place on a wire rack to cool completely before cutting into bars.
Store:
Store the blueberry yogurt protein bars in an airtight container in the refrigerator for freshness.
