To prepare a Heather's vegan meringues recipe, first you need to gather your ingredients. First, you'll need the following ingredients: 1 cup (240 ml) caster sugar 1 tablespoon (25 g) cocoa powder 2 tablespoons (60 milliliters) vegetable oil 1 teaspoon (2.5 grams) vanilla extract Instructions: Preheat the oven to 375?F (190?C) and grease and flour two 8-inch (22-centimeter) round baking pans. In the bowl of an electric mixer, cream the butter and sugar until light and fluffy. Add the egg and vanilla and beat until combined. Gradually add the dry ingredients to the wet mixture, beating well after each addition. Scoop the mixture into the prepared pan and bake for 20 to 25 minutes or until the edges are golden brown. Allow to cool before cutting into squares and serving.
