- 2 eggs, separated
- 1/2 cup butter, softened
- 1 cup packed brown sugar
- 2/3 cup milk
- 1/2 teaspoon vanilla extract
- 1 1/2 cups cake flour
- 1 1/4 teaspoons pumpkin pie spice
- 1/2 teaspoon baking soda
- 1/4 teaspoon cream of tartar
- 1/4 cup sugar

- Combine the flour, pumpkin pie spice and baking soda; add to the creamed mixture until combined. Fill paper-lined muffin cups half full. Bake at 350 degrees F for 20 minutes.
- Add cream of tartar to egg whites; beat on medium speed until soft peaks form. Gradually beat in sugar, 1 tablespoon at a time, on high until stiff peaks form and sugar is dissolved. Fold in nuts. Spread about 2 tablespoons over each cupcake.
