Ingredients
Method
- 1. Prepare the pan: Line a 6-inch round cake pan (or 9×5 loaf pan) with parchment paper. Spray with non-stick spray and set aside.
2. Cream butter and sugar: In a bowl, beat ¼ cup butter with ½ cup sugar until light and fluffy.
3. Add wet ingredients: Mix in the egg white, sour cream, milk, vanilla, and almond extract until well combined.
4. Add dry ingredients: Stir in salt, baking powder, and flour just until incorporated. Do not overmix.
5. Fold in sprinkles: Gently mix in the sprinkles, being careful not to break them.
6. Bake: Pour batter into the prepared pan. Bake at 350°F (175°C) for 25–30 minutes, or until a toothpick comes out clean. Cool completely before frosting.
7. Make buttercream: Beat ¼ cup butter with powdered sugar. Add milk (a tablespoon at a time) until frosting is smooth and spreadable. Flavor with vanilla or almond extract.
8. Frost and decorate: Place the cooled cake on a stand, spread frosting evenly over the top and sides, and decorate generously with sprinkles.

Notes
Store leftover cake in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 4 days. If refrigerated, let it come to room temperature before serving so the frosting softens again.
