Instructions

1. 1

   In a large mixing bowl, whisk together the certified gluten-free all-purpose flour blend, xanthan gum (if using), certified gluten-free baking powder, and salt until thoroughly combined and no lumps remain. This ensures even distribution of leavening agents and structure builders.

2. 2

   In a separate medium bowl, whisk together the warm water or unsweetened almond milk, egg yolks, and neutral oil or melted unsalted butter until smooth and emulsified. The mixture should be a uniform pale yellow.

3. 3

   Pour the wet ingredients into the dry ingredients and mix with a whisk or spatula until just combined, forming a thick, smooth batter. Be careful not to overmix; gluten-free batters can become tough if overworked. The batter will be quite thick and may feel slightly sticky.

4. 4

   In a clean, dry bowl, whip the egg whites with an electric mixer on medium speed until foamy. Add the cream of tartar (if using) and continue whipping on high speed until stiff, glossy peaks form. The egg whites should hold their shape when the beaters are lifted, indicating they are properly aerated and stable.

5. 5

   Gently fold about one-third of the whipped egg whites into the thick batter to lighten it. Then, carefully fold in the remaining egg whites in two additions until no white streaks remain, being careful not to deflate the airy mixture. The final batter should be light and voluminous.

6. 6

   Pour the batter into an ungreased 8-inch tube pan, spreading it evenly. Gently tap the pan on the counter a few times to release any large air bubbles. Bake in a preheated oven at 325°F (160°C) for about 25-30 minutes, or until the cake is golden brown, springs back when lightly touched, and a wooden skewer inserted into the center comes out clean. The aroma should be sweet and baked.

7. 7

   Immediately upon removing the cake from the oven, invert the pan by placing it upside down on its legs or over a bottle. Allow the cake to cool completely upside down for at least 2-3 hours, or until it releases easily from the pan. This cooling method prevents the delicate cake from collapsing.

Tips & Notes

• Too much xanthan gum makes baked goods rubbery — stick precisely to the recipe amount.
• Tapioca thickens sauces and gravies at a lower temperature than cornstarch; add it near the end of cooking.
• Check that your baking powder is labeled gluten-free — some brands use grain-based fillers — look for certified gluten-free on the label.
