Vanilla Cupcakes

Makes about 14 cupcakes

Ingredients
5 organic egg whites
Pinch of salt
3 tablespoons honey
2 teaspoons vanilla extract
1/4 cup nonfat Greek yogurt
1/2 cup whole wheat flour
1 teaspoon baking powder

For the frosting
1 cup nonfat cream cheese
1/2 ripe banana

Method

• Preheat the oven to 325F.
• Place the egg whites in a large bowl and using a handheld mixer whip the whites on medium speed for 3 to 4 minutes or until the whites begin to lighten up and hold their shape.
• Increase speed to high and whip in the salt and honey until the whites hold a soft peak, then add the vanilla extract.
• Fold in the yogurt.
• In a separate medium mixing bowl combine the flour and baking powder and mix well.
• Sift the dry ingredients into the egg whites a little at a time, gently folding them in with a rubber spatula.
• Once fully incorporated, scoop the batter into cupcake tins lined with cupcake papers.
• Bake the cupcakes for 15 to 20 minutes or until they have colored and gently spring back when pushed with a finger.
• Remove from the oven and cool the cupcakes at room temp.
• Mix the cream cheese and the banana in a medium mixing bowl until well incorporated, leaving small chunks of banana throughout the frosting.
• Once cool, spread a little of the banana frosting over the cupcakes and serve.
