Preheat the oven to 340 degrees. Set parchment paper on your baking pan and set aside.
In a standing mixer or large bowl, mix the butter until smooth and combine with sugar.
Little by little add in the egg whites until combined.
In another bowl, sift the flour, baking powder, and baking soda. Mix until evenly combined.
In a small sauce dish mix the yogurt with the milk and vanilla. Once it is combined add it little by little into your butter mixture, alternating with the dry ingredients. Scrape the sides to make sure you have all the ingredients.
Mix until smooth and try not to over mix. Fold in the sprinkles and pour the batter onto your baking pan.
Place in the oven and bake for 25 to 30 minutes until you stick a toothpick in and it comes out clean.
Remove from the oven and let it cool.
Once it is completely cool, spread the buttercream and top with Funfetti sprinkles.
