Preheat your oven to 350°F (180°C) and line a square baking pan with parchment paper. This prevents sticking and makes it easier to remove the brownies later.
In a large mixing bowl, whisk together the flour, sugar, baking powder, vanilla extract, and salt.
Step 2: Melt the Chocolate
Melt the dark chocolate and coconut oil using a double boiler (bain-marie) or microwave in 20-second intervals, stirring each time until smooth.
Once melted, stir in the applesauce and plant-based milk, mixing well to create a creamy, smooth consistency.
Step 3: Combine Wet and Dry Ingredients
Pour the melted chocolate mixture into the dry ingredients.
Gently fold everything together with a spatula until you have a thick, lump-free batter.
Step 4: Add the Walnuts
Stir in the chopped walnuts, making sure they’re evenly distributed.
If you love extra crunch, sprinkle a handful of whole walnut pieces on top before baking.
Step 5: Bake the Brownies
Pour the batter into the prepared baking pan and spread it evenly.
Bake for 25 to 30 minutes. To check doneness, insert a toothpick or knife in the center—if it comes out slightly moist, the brownies will be perfectly fudgy.
Step 6: Let Cool and Serve
Allow the brownies to cool completely before cutting. This helps them set properly and makes slicing easier.
