Difficulty: Intermediate

Cuisine: American

Yield: 16 Servings (16 bars)

Dietary: Vegetarian

Ingredients

→ Dry Base

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

→ Wet Ingredients

07 6 tablespoons melted butter (unsalted)
08 1 teaspoon vanilla essence

→ Filling

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

Instructions

Step 01

Preheat your oven to 375°F (190°C). Grab an 8-inch square pan and line it with parchment paper, making sure to leave some overhang so you can pull the bars out easily later.

Step 02

Stir together the oats, flour, brown sugar, baking soda, salt, and cinnamon in a mixing bowl. Pour in the vanilla and melted butter, then stir until it forms a crumbly dough.

Step 03

Take half of your crumb mixture and press it down evenly into the lined pan, making sure it’s nice and firm.

Step 04

Toss the blueberries, granulated sugar, and cornstarch in a bowl until everything’s coated thoroughly. Pour this mixture over the base layer.

Step 05

Sprinkle the rest of the oat mixture on top of the berries and press it down gently to keep it in place.

Step 06

Bake for 35-40 minutes, or until the top looks golden and the blueberries are bubbling. Let it cool completely in the pan before lifting it out using the parchment paper, then slice it into squares.

Notes

  1. If you want a zingy twist, add the zest of one lemon to the blueberry filling.
  2. For a nutty crunch, swap in some almond meal for part of the flour.
  3. Stored in an airtight container, these squares stay fresh for roughly 5 days.
