1 cup unsalted butter, softened
4 cups powdered sugar
2 teaspoons vanilla extract
2 to 3 tablespoons heavy cream (or milk)
Instructions
Make the cake:
Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
In a large bowl, beat butter and sugar together until light and fluffy, about 3 to 4 minutes.
Add eggs, one at a time, beating well after each addition. Beat in vanilla extract.
Gradually add dry ingredients to wet ingredients, alternating with milk, beginning and ending with dry ingredients. Mix until well combined.
Divide batter evenly between prepared pans and smooth tops.
Make the crumbled topping:
In a medium bowl, whisk together brown sugar, granulated sugar, and cinnamon.
Pour in melted butter and mix until smooth. Add flour and mix until large crumbs form.
Spread crumb mixture evenly over top of each cake layer before baking.
Bake Cake:
Bake cakes for 30 to 35 minutes or until a toothpick inserted in the center comes out clean.
Let cakes cool in pans for 10 minutes before transferring to a wire rack to cool completely.
Make Buttercream Frosting:
In a large bowl, beat butter until creamy. Gradually add powdered sugar, 1 cup at a time, mixing well after each addition.
Beat in vanilla extract. Add heavy cream, 1 tablespoon at a time, until frosting reaches desired consistency.
Assemble the Cake:
Place one cake layer on a serving plate or cake stand. Spread a generous layer of buttercream frosting on top.
Place the second cake layer on top and frost the top and sides of the cake. Smooth the frosting or create decorative swirls as desired.
Garnish with leftover crumbs or additional sprinkles for added texture.
