Preheat your oven to 350°F (175°C). Grease the baking pan or line it with parchment paper for easy removal.
In a mixing bowl, combine the rolled oats, almond flour, cocoa powder, baking powder, and salt. Stir until all dry ingredients are well mixed.
In another bowl, mix together the honey (or maple syrup), almond butter, and vanilla extract until smooth.
Pour the wet mixture into the dry ingredients and stir until just combined.
Fold in the dark chocolate chips until evenly distributed throughout the mixture.
Spread the mixture evenly into the prepared baking pan, pressing it down firmly.
Bake in the preheated oven for 20 to 25 minutes, or until the edges start to pull away from the sides of the pan and the center is set.
Remove from the oven and allow the bars to cool in the pan for about 10 minutes before transferring to a wire rack to cool completely.
Once cooled, cut into 12 bars and enjoy!
