Preheat oven to 350°F (175°C) and line an 8x8-inch baking dish with parchment paper.

In a mixing bowl, combine rolled oats, blueberries, honey or maple syrup, almond meal, egg, melted coconut oil, vanilla extract, and salt. Stir until evenly mixed.

Transfer the mixture into the prepared baking dish and spread evenly, pressing down to form a compact layer.

Bake in the oven for about 35 minutes until golden brown on top. The bars should feel firm.

Allow to cool for at least 15 minutes before lifting out of the dish using parchment paper and cutting into squares or rectangles.
