- Preheat your oven to 350°F (175°C) and line an 8x8-inch baking pan with parchment paper.
- Whisk together the cake flour, baking powder, baking soda, and salt in a mixing bowl. Set aside.
- Cream the warmed browned butter and granulated sugar until smooth and fluffy, about 3-4 minutes.
- Add the room-temperature egg whites and mix until light and airy, then mix in vanilla extract.
- Incorporate the sour cream, then alternately add dry ingredients and milk to the mixture, starting and ending with dry ingredients.
- Pour the batter into the prepared pan, smooth the top, and bake for approximately 35 minutes.
- While the cake cools, beat the unsalted butter for frosting, gradually adding confectioners' sugar until smooth. Infuse with vanilla and a splash of milk.
- Add sky blue gel food coloring to the frosting and adjust until the desired color is achieved.
- Spread the frosting evenly over the cooled cake.
- Whisk cocoa powder with vanilla extract, then flick onto the frosting to create the speckled effect.
- Slice the cake into squares and serve to guests.

Notes
Use room temperature ingredients for a fluffier cake and avoid overmixing for a light texture. Store in an airtight container.
