These breakfast bars blend juicy blueberries with hearty oats for a truly filling morning treat. The soft base holds sweet berries while the crunchy top gives you that amazing texture you'll crave.
Must-Have Ingredients
- Old-fashioned oats: Gives that nice chew and holds everything together
- All-purpose flour: Makes the base soft and cake-like
- Brown sugar: Adds that hint of molasses and keeps things moist
- Butter: Go for European-style if you can find it
- Fresh blueberries: Try to grab wild ones for bigger flavor
- Cornstarch: Keeps berry juice from making things soggy
- Vanilla: Always go with the real stuff
- Cinnamon: Brings that cozy warmth to every bite
Step-by-Step Guide
- Get Your Oven Ready
- Put your rack right in the middle. Heat to 375°F. Put parchment in your pan with extra hanging over the sides.
- Mix Your Dry Stuff
- Put oats, flour, brown sugar, baking soda, and salt in a bowl. Stir it all up good.
- Add The Wet Ingredients
- Drizzle melted butter and vanilla over everything dry. Stir until it looks like crumbs.
- Make The Foundation
- Push half your crumb mix into the pan. Make sure it's flat and even.
- Load Up The Berries
- Toss blueberries with sugar and cornstarch. Spread them all over your base.
- Add The Top Layer
- Scatter what's left of your oat mix over the berries. Press down just a little.
- Pop It In The Oven
- Bake for 35-40 minutes until it's golden and you see berry bubbles.
- Let It Rest
- Let it cool all the way in the pan. Use the parchment to lift it out. Cut with a sharp knife.
