Pastel Buttercream Sprinkle Birthday Cake PT70M https://img3.recipesrun.com/201907/2019/1107/91/c/973254/300x200x90.jpg Sprinkle Birthday Cake filled and frosted with simple, whipped vanilla buttercream. Pastel rosettes and swirls make the outside just as cheery as the inside! Speaking of love, this cake is all about loving yourself. I unapologetically covered this cake in buckets of buttercream because that's what made me happy. The inside is filled with sprinkles, because duh – it's a birthday cake. But the frosting is were art meets pastry. 8 servings Ingredients: 2 tbsp. milk 1/4 tsp. almond extract, optional 1 tsp. vanilla bean paste, or vanilla extract 3 1/2 cups powdered sugar 1 1/2 cup unsalted butter, softened 1/2 cup rainbow sprinkles 1 cup buttermilk 1 whole egg 3 egg yolks 2 tsp. pure vanilla extract 1 1/2 cups granulated sugar 3/4 cup unsalted butter, at room temperature 1/2 tsp. salt 1 tbsp. baking powder 2 1/3 cups cake flour
