Follow these simple steps to create your own Blueberry Oatmeal Breakfast Bars:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease or line an 8×8-inch baking pan with parchment paper.
2. Mix Dry Ingredients: In a large bowl, combine rolled oats, flour, baking powder, salt, and cinnamon (if using).
3. Mix Wet Ingredients: In another bowl, whisk together honey (or maple syrup), almond milk, and vanilla extract until well blended.
4. Combine Mixtures: Pour the wet ingredients into the dry ingredients, stirring to combine. Add the blueberries and nuts, folding gently to avoid breaking the berries.
5. Pour into Pan: Transfer the mixture to the prepared baking pan, spreading it evenly.
6. Bake: Bake in the preheated oven for 25-30 minutes or until the top is golden and a toothpick inserted in the center comes out clean.
7. Cool: Once baked, remove from the oven and allow to cool in the pan for about 10-15 minutes before transferring to a wire rack to cool completely.
8. Cut into Bars: Once cooled, cut into squares or rectangles.
9. Store: Keep leftovers in an airtight container at room temperature for a few days or in the fridge for longer freshness.
