Preheat your oven to 325°F (163°C) and prepare an 8x8-inch baking pan by lining it with parchment paper or greasing it.
In a large bowl, whisk together Greek yogurt, maple syrup (or honey), eggs, and vanilla extract until smooth and well-blended.
Sift in the cocoa powder, baking powder, and salt, stirring everything together until the mixture is smooth and chocolatey.
Gently fold in the almond flour (or oat flour), mixing just enough to combine. The batter should be thick and rich.
Stir in the chocolate chips, ensuring they’re evenly distributed without overmixing.
Transfer the batter into the prepared pan and bake for 18 minutes.
When tested with a toothpick, it should emerge with a few moist crumbs.
Allow the brownies to cool before slicing. Enjoy!
