Ingredients

→ Dry Base

01 1 cup old-fashioned oats
02 3/4 cup all-purpose flour
03 1/3 cup light brown sugar
04 1/4 teaspoon baking soda
05 1/4 teaspoon salt

07 6 tablespoons unsalted butter, melted
08 1 teaspoon vanilla extract

→ Filling

09 1 cup blueberries
10 1/4 cup granulated sugar

Instructions

Step 01

Get your oven warming to 375°F (190°C) and line an 8-inch square pan with parchment paper, leaving extra hanging over the sides for easy lifting later.

Step 02

Combine your oats, flour, brown sugar, baking soda, salt, and cinnamon in a bowl until well mixed. Pour in the melted butter and vanilla, stirring until you've got a nice crumbly mixture.

Step 03

Take half of your crumbly oat mixture and press it firmly into your lined pan, making sure it's even and well-packed.

Step 04

Toss your blueberries with the granulated sugar and cornstarch until they're evenly coated. Spread this mixture over your pressed oat base.

Step 05

Sprinkle the remaining oat mixture over your blueberries, giving it a gentle press to set it in place.

Step 06

Let it bake for 35-40 minutes until you see golden brown peaks and bubbling blueberries. Cool completely before lifting out with the parchment paper and cutting into squares.
