# What You Need:

→ Dry Ingredients

01 - 2 cups old-fashioned rolled oats
02 - 1/2 cup vanilla protein powder
03 - 1/2 teaspoon ground cinnamon
04 - 1/4 teaspoon salt
05 - 1 teaspoon baking powder

→ Mix-Ins

12 - 1 cup fresh or frozen blueberries (if frozen, do not thaw)

# Directions:

01 - Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper, leaving overhang for removal.
02 - In a large bowl, whisk together rolled oats, protein powder, cinnamon, salt, and baking powder.
03 - In a separate bowl, mash bananas until smooth; add honey or maple syrup, applesauce, eggs, vanilla, and melted coconut oil, then whisk until combined.
04 - Pour wet ingredients into dry ingredients and stir gently until just combined.
05 - Carefully fold in blueberries, avoiding overmixing, especially if using frozen berries.
06 - Spread the mixture evenly into the prepared baking pan.
07 - Bake for 28 to 32 minutes until bars are golden and a toothpick inserted in the center comes out clean.
08 - Allow to cool completely in the pan, then lift out using parchment overhang and cut into 12 bars.

# Expert Advice:

01 -
  • They're dense and chewy enough to feel indulgent, but you know exactly what's inside them.
  • One bar with coffee actually keeps you full until lunch, which is rare for something this simple.
  • The blueberries burst slightly as they bake, creating little pockets of sweetness throughout.
02 -
  • If you cut the bars while they're still warm, they'll crumble apart; wait until they're completely cool, and they'll slice like they were meant to.
  • Frozen blueberries work just as well as fresh ones, and sometimes better because they don't release as much moisture into the batter.
03 -
  • Don't thaw frozen blueberries; they stay intact and keep the batter from turning purple if you fold them in gently.
  • The parchment paper overhang is non-negotiable—it makes removing the entire sheet a one-handed operation, and cleanup is instant.
