How to Make happy birthday caker

1. Preheat your oven to 350°F and grease two 9-inch round cake pans. Line the bottoms with parchment paper for easy release.
2. In a medium bowl, whisk together the flour, baking powder, and salt; set aside.
3. In a large bowl, beat the softened butter and sugar with an electric mixer on medium speed until light and fluffy, about 4 minutes.
4. Add the eggs one at a time, beating well after each addition, then mix in the vanilla extract.
5. Alternately add the dry ingredients and milk in three parts, starting and ending with the dry ingredients, mixing each just until combined. Gently fold in the sour cream and half of the sprinkles for color and fun texture.
6. Divide the batter evenly between the prepared pans and smooth the tops. Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean.
7. Let the cakes cool in the pans for 10 minutes, then invert onto wire racks to cool completely.
8. Once cooled, spread a thick layer of vanilla frosting on one cake layer, sprinkle some extra rainbow sprinkles on top, then stack with the second layer. Frost the top and sides smoothly and finish with remaining sprinkles.
9. Chill the cake for at least 30 minutes before slicing and serving to set the frosting.

Tips for the Best Results

• Use room temperature ingredients for a smoother batter and even baking.
• Don’t overmix the batter to keep the cake tender and light.
• Line your pans with parchment paper to prevent sticking and easy removal.
• For extra color, fold in sprinkles gently to avoid bleeding into the batter.
• Chill the cake before slicing to help keep clean edges and prevent frosting smudging.

Storage and Reheating

Store your happy birthday caker covered tightly in the refrigerator for up to 5 days. This keeps the frosting fresh and the cake moist. Before serving, let it sit at room temperature for about 30 minutes to soften slightly.

If you want to freeze the cake, wrap it securely in plastic wrap and then aluminum foil. Freeze for up to 3 months. Thaw overnight in the fridge and bring to room temperature before serving.
