KING ARTHUR GLUTEN FREE ANGEL FOOD CAKE RECIPES

Steps:

• Preheat Oven. Adjust oven rack to the middle position and remove the top rack. Preheat oven to 350°F (180°C). Sift gluten-free flour and set aside.(This removes any lumps in the gluten-free flour.)
• Whip the Egg Whites. Stir together granulated sugar, cream of tartar, and salt in the bowl of a stand mixer fitted with the whisk attachment. Add egg whites and vanilla extract. Whisk on low to combine, about 1 minute. Increase speed to medium-high (6-8 on a KitchenAid) and whip 6 minutes.Increase speed to high (10 on a KitchenAid) and whip until the meringue is shiny, white, and thick. This takes between 2-4 minutes. The tines of the whisk should leave a pattern in the meringue. Stop the mixer and remove the whisk attachment from the bowl. The meringue clinging to the whisk should form a very soft peak. You want it to fall in a thick ribbon off the whisk. Replace the whisk and turn the mixer back on to high speed.
• Slowly the Gluten-Free Flour. Add the flour, 1/4 cup at a time, and mix until incorporated. Allow each addition of flour to incorporate before adding the next.
• Bake the Cake. Spoon batter into an ungreased 10-inch aluminum tube pan. Bake until the cake is golden brown and firm to the touch, about 50 minutes. (The internal temperature of the cake should be 206°F.)
• Cool the Cake. Remove pan from the oven and immediately invert onto the legs of the pan. If the pan does not have legs, invert onto the neck of a wine bottle. Cool for at least 2 hours. If the kitchen is cold, place the pan on top of the oven to cool and prop the oven door open. 
• Remove the Cake from the Pan. Slide an offset spatula around the sides of the cake to loosen. Remove the insert, and slide a spatula under the bottom of the cake. Gently lift the cake off the insert and place onto a serving dish. To serve, cut with a serrated knife. Store leftovers wrapped tightly in plastic for up to 1 week at room temperature.

Steps:

• Place egg whites in a large bowl; let stand at room temperature for 30 minutes. Sift 3/4 cup sugar, cornstarch, flours and potato starch together twice; set aside., Add cream of tartar, salt and vanilla to egg whites; beat on medium speed until soft peaks form. Gradually add remaining sugar, about 2 tablespoons at a time, beating on high until stiff peaks form. Gradually fold in flour mixture, about 1/2 cup at a time., Gently spoon into an ungreased 10-in. tube pan. Cut through the batter with a knife to remove air pockets. Bake on the lowest oven rack at 350° for 45-50 minutes or until lightly browned and entire top appears dry. Immediately invert pan; cool completely, about 1 hour., Run a knife around side and center tube of pan. Remove cake to a serving plate. Top with fresh fruit if desired.
