Preheat the oven to 350°F/180°C. Line a square 8×8 baking pan with parchment paper and set it aside.
In a large bowl, whisk together the applesauce and honey until well combined. Add the two eggs and vanillla and continue whisking.
1/2 cup unsweetened applesauce*, 1/2 cup honey, 2 eggs, 1 tbsp vanilla
Add in the cocoa powder, flour, baking soda, and salt. Switching to a spatula, gently fold these dry ingredients in until no dry streaks appear and a brownie batter forms.
1/2 cup unsweetened cocoa powder, 1/2 cup all-purpose flour, 1/2 tsp baking soda, 1/2 tsp salt
Optional: Add in chocolate and mix in a few times.
1/2 cup dark chocolate
Transfer the brownie batter into the prepared pan and spread evenly. Top off with more chocolate.
Bake the brownies for 22-26 minutes. Mine took 26 minutes exactly. The brownies will look shiny on the top, and a toothpick inserted will come out fudgy, but not wet like batter.
Allow the brownies to cool, slice, and enjoy!
