Soft, chewy bars loaded with blueberries and oats for a wholesome, energizing start or snack.

# What You'll Need:

→ Dry Ingredients

01 - 2 cups old-fashioned rolled oats
02 - 1 cup whole wheat flour
03 - 1/2 cup light brown sugar, packed
04 - 1/2 teaspoon baking powder
05 - 1/4 teaspoon ground cinnamon
06 - 1/4 teaspoon salt

→ Wet Ingredients

07 - 1/2 cup unsalted butter, melted and cooled
08 - 1/4 cup plain Greek yogurt
09 - 1 large egg
10 - 1 teaspoon pure vanilla extract

→ Blueberry Mixture

11 - 2 cups fresh blueberries, or frozen thawed and drained
12 - 2 tablespoons granulated sugar
13 - 1 tablespoon cornstarch
14 - 1 tablespoon fresh lemon juice

# Directions:

01 - Preheat oven to 350°F. Line a 9x9-inch baking pan with parchment paper, leaving overhang for easy removal.
02 - In a large bowl, whisk together oats, whole wheat flour, brown sugar, baking powder, cinnamon, and salt.
03 - In a separate bowl, whisk together melted butter, Greek yogurt, egg, and vanilla extract until smooth and fully combined.
04 - Add wet ingredients to dry ingredients and mix until just combined. Reserve 1 cup of this mixture for topping.
05 - Press remaining oat mixture evenly into the prepared pan to create an even base layer.
06 - In another bowl, toss blueberries with granulated sugar, cornstarch, and lemon juice until evenly coated.
07 - Spread blueberry mixture over the oat base, then crumble reserved oat mixture evenly over the blueberries.
08 - Bake for 30 to 35 minutes, or until the top is golden brown and the filling is bubbling at the edges.
09 - Allow bars to cool completely in the pan. Lift out using parchment paper overhang, cut into 16 bars, and wrap individually.

# Expert Tips:

01 -
  • They taste indulgent but actually feel good to eat, packed with whole grains and real fruit without any guilt.
  • Honestly, they're foolproof—no fancy techniques or temperamental doughs, just mixing and pressing.
02 -
  • Don't skip cooling completely; cutting warm bars is a heartbreaker, and you'll end up with beautiful crumbles instead of neat squares.
  • The cornstarch in the filling is non-negotiable—without it, the blueberry mixture will be soupy and seep into your base, making the bottom layer soggy.
03 -
  • Keep an eye on your blueberries while they sit in the sugar mixture—if too much liquid pools, drain it off before spreading or your base will get soggy.
  • Room temperature butter and yogurt mix more smoothly with the egg; if yours are cold from the fridge, give them a few minutes on the counter first.
