Ingredients

→ Dry Mix

01 1/2 teaspoon ground cinnamon
02 1/4 teaspoon table salt
03 1/4 teaspoon baking soda
04 1/3 cup packed light brown sugar
05 3/4 cup plain flour
06 1 cup rolled oats

→ Liquids

07 1 teaspoon vanilla essence
08 6 tablespoons melted unsalted butter

→ Middle Layer

09 2 teaspoons of cornstarch
10 1/4 cup white sugar
11 1 cup fresh blueberries

Instructions

Step 01

Turn the oven to 375°F (190°C) and line an 8-inch square dish with parchment, leaving some overhang to help lift it out later.

Step 02

Mix together the oats, flour, sugar, cinnamon, salt, and baking soda in a bowl. Stir in the melted butter and vanilla until you get a crumbly dough.

Step 03

Use half the crumb mixture and firmly press it into the bottom of the prepared pan in an even layer.

Step 04

In a bowl, toss the blueberries with cornstarch and white sugar until they're fully coated. Spread this over the pressed base evenly.

Step 05

Scatter the rest of the crumbly dough across the blueberries, pressing gently so it sticks together.

Step 06

Bake for 35-40 minutes or until the top is golden and blueberries are bubbly. Cool completely before lifting out with the parchment and slicing into squares.

Notes

  1. Grate some lemon zest into the blueberry mix for a tangy twist
  2. Swap some of the flour with almond flour for added crunchiness
  3. Keep leftovers in an airtight container—they'll stay fresh for up to five days!
