To prepare a perfect vegan sugar cookies recipe, first you need to gather your ingredients. First, you'll need your flour, baking powder, sugar, salt, and cocoa powder. Then, add your wet ingredients to the dry ingredients and mix them together until they're combined. Now, take your cookie dough and roll it out until it's about 1/4 of an inch thick. You want the dough to be about 1/8 of the way up the side of your baking sheet. Place the cookies on the cookie sheet and bake them for 10 to 12 minutes or until the edges are golden brown. Let them cool in the pan for 5 to 10 minutes before transferring them to an airtight container to cool completely.
