Start by preheating your oven to 350°F (175°C). Line an 8x8 inch baking pan with parchment paper, allowing some overhang for easy lifting later.
In a medium mixing bowl, combine the whole wheat flour, unsweetened cocoa powder, coconut sugar, baking powder, baking soda, and salt. Use a whisk to blend these dry ingredients thoroughly, ensuring there are no lumps.
In a separate bowl, add the eggs, Greek yogurt, applesauce, and vanilla extract. Whisk these wet ingredients together until you achieve a smooth and creamy consistency.
Slowly add the combined dry ingredients into the wet mixture, stirring gently with a spatula or wooden spoon until just combined. Aim to avoid over-mixing, as this can result in denser brownies.
If you’re feeling decadent, gently fold in the dark chocolate chips at this stage, which will add rich pockets of chocolate throughout the brownies.
Pour the brownie batter into the prepared baking pan, spreading it evenly to ensure uniform baking.
Bake in the preheated oven for 25-30 minutes. Check for doneness by inserting a toothpick into the center; it should come out with a few moist crumbs attached, but not wet batter.
Once baked, allow the brownies to cool in the pan for about 10 minutes. Carefully lift them out using the parchment paper and transfer them to a wire rack to cool completely.
Once fully cooled, cut the brownies into squares and serve.
Notes
Elevate your brownies by dusting them lightly with cocoa powder or powdered sugar just before serving. Consider adding fresh berries on the side or a dollop of whipped Greek yogurt for a creamy contrast.
