Preparation
- Preheat your oven to 350°F (175°C) and ungrease the 9-inch tube pan.
- Sift the cake flour at least 4-5 times, then whisk in 3/4 cup sugar and 1/3 cup rainbow sprinkles.
- Whip the egg whites with cream of tartar, vanilla extract, and salt until frothy.
- Gradually add the remaining sugar while whipping until stiff peaks form.
- Fold the flour and sprinkles mixture into the whipped egg whites gently.
- Pour the batter into the prepared tube pan, smooth the top, and tap to release air bubbles.
- Bake for 45-50 minutes until golden brown and a skewer comes out clean.
- Invert the cake and cool completely in this position for 1-2 hours.
- Meanwhile, prepare the frosting by whisking sugar and egg whites over simmering water until dissolved, then cool and whip until fluffy.
- Once the cake is cool, frost it and decorate with additional rainbow sprinkles.

Notes
Use egg whites at room temperature for the best results. Ensure all equipment is clean to achieve maximum volume in egg whites. Cool the cake upside down to maintain its fluffy texture.
