Method
For the Funfetti Cupcake
- Preheat the oven to 375°F. For 2 8-inch layers double this recipe and bake at 325°F.
- Start making the cake by mixing the cake flour, baking powder, baking soda, salt and 35 grams of the sugar together in a bowl until evenly combined.
- Separate your eggs (placing the egg whites in a clean bowl) then add the egg yolks, oil, vanilla and vanilla yogurt to the bowl from step 1 and mix until evenly combined.
- To your clean bowl containing the egg whites, add the lemon juice and whip until frothy. They should have at least doubled in volume at this point.
- Once your egg whites are frothy gradually add the rest of the sugar over about 30 t0 45 seconds.
- Once all the sugar is added continue to whip the egg-whites until soft peaks form. Do NOT whip to stiff peaks.
- Add the sprinkles to the cake batter from step 2 then add the whipped egg whites from the previous step. Gently fold in both until evenly combined (thin ribbons of egg white are ok).
- Scoop the batter into lined cupcake tins, filling each tin 3⁄4 of the way.
- Bake for 12-16 minutes or until cupcakes have a golden color and a toothpick comes back with a couple crumbs when inserted. Allow to cool completely before decorating
For the Swiss Meringue
- While the cupcakes cool, start making the Swiss meringue buttercream. Add the meringue powder and water (or egg whites) along with the salt and granulated sugar to a large bowl and, over a double boiler, whisk until sugar has dissolved completely.Test by touching the mixture to your fingertips - it should be sticky but smooth. If you feel any graininess, return to the double boiler until smooth. This takes about 3-6 minutes.
- Once meringue powder mixture is smooth, whip into a meringue for 5-7 minutes or until firm, glossy peaks form.
- Cut your softened butter into chunks (approximately half to 1-inch cubes) and add one at time waiting until the previous is completely incorporated before adding another.
- Once all the butter has been added to the buttercream, add the confectioner's sugar & lemon juice and whip again until smooth.
- Using a piping bag with your piping tip of choice, or simply just a spatula, pipe or spread the buttercream onto your cooled funfetti birthday cupcakes and enjoy! For best flavor store in an airtight container and enjoy within 2 days.
