# Needed Ingredients:

→ 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

12 - 2 tablespoons granulated sugar
13 - 1 tablespoon cornstarch
14 - 1 tablespoon fresh lemon juice

# Steps:

01 - Preheat oven to 350°F. Line a 9x9-inch baking pan with parchment paper, leaving overhang on sides for easy removal.
02 - In a large mixing bowl, combine 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.
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 prepared pan to create a compact, even base.
06 - In another bowl, toss blueberries with granulated sugar, cornstarch, and lemon juice until evenly coated.
07 - Spread blueberry mixture evenly over oat base.
08 - Crumble reserved oat mixture evenly over blueberries.
09 - Bake for 30 to 35 minutes, or until top is golden brown and filling is visibly bubbling at edges.
10 - Cool completely in pan. Lift out using parchment paper overhang. Cut into 16 bars and wrap individually.

# Expert Advice:

01 -
  • They're genuinely guilt-free—no refined sugar overload, just real oats and fruit doing the heavy lifting.
  • You can make them once and eat them for days, which means less morning scrambling and more actual time with your coffee.
  • They wrap beautifully in parchment, so they're perfect for sharing or pretending you baked them for people when you actually just planned ahead.
02 -
  • The blueberries will release liquid as they bake, and that's exactly what you want—the cornstarch thickens it into a proper filling instead of letting it soak into the base.
  • Cutting them while still warm is a recipe for crumbling chaos; let them cool fully, and they'll slice cleanly and hold their shape like they actually know what they're doing.
03 -
  • Let your melted butter cool slightly before adding it to the egg—a too-hot mixture will scramble the egg and create tiny cooked bits in your batter.
  • The parchment paper overhang is genuinely life-changing; it transforms getting these out of the pan from a wrestling match into an elegant lift.
