Begin by preheating your oven to 350°F (175°C). Prepare an 8x8 inch baking dish by lining it with parchment paper, allowing some edges to hang over for easy removal later.
In a spacious mixing bowl, combine the rolled oats, baking powder, ground cinnamon, and a pinch of salt. Mix these dry ingredients thoroughly until well combined.
In another bowl, whisk together the almond milk, almond butter, maple syrup, and pure vanilla extract until the mixture is smooth and homogenous.
Carefully pour the wet mixture into the bowl with the dry ingredients. Stir gently until just combined. Be cautious not to over-mix! Then, fold in the mixed berries (and optional chocolate chips or nuts) until evenly distributed throughout the mixture.
Transfer the mixture to the prepared baking dish. Use a spatula to spread the mixture evenly across the dish, pressing down firmly to ensure it holds together during baking.
Place the baking dish in the preheated oven and bake for 25-30 minutes. Keep an eye on it; it’s done when the edges turn lightly golden brown and a toothpick inserted in the center comes out clean.
Once out of the oven, let the bars cool in the pan for about 10 minutes. After that, use the parchment paper to lift them out carefully and transfer them to a wire rack to cool completely.
Once the bars have cooled, cut them into squares or rectangular bars according to your preference. They can be stored in an airtight container in the refrigerator for up to 5 days, making them a perfect grab-and-go snack!
