To prepare a vegan christmas tree brownies recipe, first you will need to gather your ingredients. First, you'll need the following ingredients: 14 cup (60 ml) cocoa powder 2 tablespoons (28 g) coconut oil 1 tablespoon (25 grams) vanilla extract 1 teaspoon (0.5 tsp) nutmeg Instructions: Preheat the oven to 350 degrees F (180 degrees C). Grease and flour two 9-inch (23 cm) square pans and set aside. In another large mixing bowl, combine the flour, baking powder, salt, and baking soda. Add the wet ingredients to the dry ingredients and mix to combine. Pour the brownie batter into the prepared pan and bake for 20 to 25 minutes or until the edges are set and the center is set. Allow to cool in the pan for 5 minutes before cutting into squares.
