- Using a stand mixer, mix sugar, oil and egg whites until combined. Scrape down mixing bowl with a spatula then blend on medium-high speed for one minute until frothy. Add half of gluten free flour mixture, mixing until just combined. Add vanilla and milk or milk substitute, mixing just until combined, and repeat with remaining gluten free flour mixture. Scrape down mixing bowl, if needed.
- Scoop cake batter into cupcake liners, filling 2/3 full. Bake in 350°F oven for 15-18 minutes until a toothpick inserted into center comes out clean. Place cupcakes on a cooling rack and allow to cool completely before frosting.

Using whisk attachment of mixer, cream butter or dairy free margarine and until light and fluffy. Sift powdered sugar. Add sifted powdered sugar and 3/4 teaspoon gluten free vanilla to butter mixture and blend until combined.
