Description

This Mamma Mia Cake is a scientifically-perfected vanilla sponge designed for structural integrity and a remarkably tender crumb. Utilizing a precise creaming method and buttermilk hydration, it offers a professional-grade base ideal for tiered designs and decorative frosting.

2 1/4 teaspoons baking powder
1/2 teaspoon salt
3/4 cup unsalted butter, room temperature (67°F)
1 1/2 cups granulated sugar
3 large eggs, room temperature
1 cup buttermilk, room temperature
1 teaspoon vanilla extract
300g icing sugar (for frosting)

Instructions

Preheat your oven to 350°F (177°C) and verify the temperature with an oven thermometer; grease and flour two 8-inch cake rounds and line the bottoms with parchment paper.
In a medium bowl, whisk together the all-purpose flour, baking powder, and salt to remove clumps and aerate the dry mixture.
Using a stand mixer fitted with the paddle attachment, cream the unsalted butter and granulated sugar on medium-high speed for exactly 3 minutes until pale and voluminous.
Reduce the mixer speed to medium and add the eggs one at a time, ensuring each is fully incorporated before adding the next, then mix in the vanilla extract.
Set the mixer to the lowest speed and add the dry ingredients and buttermilk in alternating additions (dry-wet-dry), starting and ending with the flour mixture.
Divide the batter evenly between the prepared pans and bake for 30-35 minutes until a toothpick inserted in the center comes out with moist crumbs or the internal temperature reaches 205°F.
Allow the cakes to cool in the pans for 10 minutes on a wire rack before inverting them onto the rack to cool completely.

Notes

Achieving the perfect emulsion depends on all liquid ingredients being at room temperature to prevent the butter from seizing. If your frosting appears grainy, ensure the icing sugar is thoroughly sifted before being whipped into the butter base. For the cleanest presentation, chill the cake layers for 30 minutes before slicing with a hot, dry knife.
