How to Make the Recipe
Now, let’s get baking! Follow these simple steps to create your very own smash cake:
- Preheat your oven to 350°F (175°C) and grease two 6-inch round cake pans.
- In a large mixing bowl, cream together 1/3 cup of softened unsalted butter and 3/4 cup of sugar until light and fluffy.
- Add in the eggs, one at a time, mixing well after each addition. Stir in 1/2 teaspoon of vanilla extract.
- In a separate bowl, combine the whole milk and sour cream. Gradually add this mixture to the butter mixture, alternating with the flour, baking soda, baking powder, and salt. Mix until just combined.
- Divide the batter evenly between the prepared cake pans and smooth the tops.
- Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Let the cakes cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.
- While the cakes are cooling, prepare the Smash Cake Frosting. In a mixing bowl, beat together 1/2 cup of softened unsalted butter and 2 1/2 cups of powdered sugar until creamy. Add in 3 tablespoons of whole milk and 1 teaspoon of vanilla extract, mixing until smooth.
- Once the cakes are completely cool, place one layer on a serving plate. Spread a layer of frosting on top, then place the second layer on top of that. Frost the top and sides of the cake with the remaining frosting.
- Finally, decorate with rainbow sprinkles for that festive touch!
Pro Tips for Making the Recipe
Here are some of my favorite tips to ensure your smash cake turns out perfectly:
- Make sure your butter is softened to room temperature for easy mixing.
- Don’t overmix the batter; mix until just combined for a light and fluffy cake.
- Feel free to customize the frosting with different colors or flavors to match your party theme!
- If you want to make this a Smash Cake Simple, you can skip the frosting and just serve the cake with some fresh fruit on the side.
How to Serve
This smash cake is not just for the little ones! Serve it at birthday parties, family gatherings, or any celebration where you want to add a touch of sweetness. Pair it with some 30-minute meals or weeknight dinner ideas for a complete festive experience. It’s also a great addition to your 1st Birthday Desserts lineup!
Make Ahead and Storage
If you want to prepare ahead of time, you can bake the cake layers a day in advance. Just wrap them tightly in plastic wrap and store them in the refrigerator. The frosting can also be made ahead and stored in an airtight container. When you’re ready to serve, simply frost the cake and add the sprinkles!
Store any leftover cake in an airtight container at room temperature for up to 3 days. If you want to keep it longer, you can freeze the cake for up to 2 months. Just make sure to wrap it well!
