My son turned the big 1 a few months ago now and I’ve been receiving a lot of questions about how to make a smash cake. You will be surprised how easy it is! I decided to make him a classic Funfetti Vanilla Birthday Cake. I also made homemade marshmallows, rice krispie treats, and a carrot cake for the dessert table.For the full party details and additional tips about styling a beautiful and simple dessert table, you can check out Landen’s First Birthday Party Recap here!

Quick note on making homemade Buttermilk: I NEVER buy Buttermilk. For one- its hard to find full fat buttermilk and I also never use an entire carton before it goes bad. So I just have Whole Milk on hand and make my own!
For every 1 cup of Whole Milk- combine 1 Tablespoon of lemon juice or distilled white vinegar. Let sit for 5-8 minutes (will start to curdle which you want- and done!).
*Recipe Adopted by Cake by Courtney
Ingredients:
- 1 cup unsalted butter (room temperature)
- 1 3/4 cups granulated sugar
- 1/3 cup grapeseed oil (or vegetable oil)
- 3 large whole eggs (room temperature)
- 3 large egg whites (room temperature)
- 3 cups cake flour
- 2 teaspoons baking powder
- 1 teaspoon salt
- 1 cup buttermilk room temperature
- 1 tablespoon vanilla extract
- 1/2 cup rainbow sprinkles
Instructions:
- Preheat the oven to 350 degrees F. Prepare three 4″ round pans with non-stick spray, parchment paper on the bottom of the pan, and another coat of spray. Set aside. *you will have leftover batter and can either make cupcakes or a 6″ cake.
- In a medium size bowl, whisk together the cake flour, baking powder and salt. Set aside.
- In the bowl of a stand mixer, fitted with the paddle attachment, beat the butter, oil, and sugar on high until fluffy and smooth, about 5 minutes.
- Add the eggs and the egg whites, one at a time to the bowl and beat on medium until well incorporated.
- Turn the mixer on low and add 1/3 of the flour mixture to the butter mixture and mix until fully incorporated. Then add half of the buttermilk and blend well, followed by another 1/3 of the flour mixture, the second half of the buttermilk and lastly, add the remaining flour mixture and mix until incorporated.
- Add the vanilla extract and beat on low until incorporated. Scrape down the sides of the bowl and mix on low for another 30 seconds. Fold in the sprinkles.
- Evenly distribute the cake batter among the three pans and bake for 20 to 25 minutes, until toothpick comes out with just a few moist crumbs on it.
- Remove cakes from the oven and let cool in pans for 10 minutes before inverting onto cooling racks.
- When cakes are completely cooled, I like to wrap each cake layer individually with plastic wrap and stick it in the refrigerator or freezer until I’m ready to frost. The cake will be easier to work with if it’s cooled a bit. If I’m making the cake a day or two before I actually need to frost it, I put it in the freezer to ensure freshness. If I’m frosting same-day, I’ll just put it in the refrigerator to chill until needed.
Frosting:
- 1 cup softened butter (allow to sit at room temp for 2 hours)
- 2 1/2-4 cups of confections sugar (depending on the sweetness level you prefer)
- 2 teaspoons of Vanilla Extract
- 1/4-1/2 cup of Heavy Whipping Cream
Instructions:
1) Using an electric mixer or hand held mixer with the paddle attachment- cream butter for 5 minutes, until lightened.
2) Add Vanilla Extract and mix until combined
3) Add powdered sugar in 1/2 cup increments. After the final 1/2 cup is incorporated, slowly add the heavy whipping cream. Beat on medium speed for 5 minutes or until frosting is light and fluffy.
*Frosting can be made up to 1 week in advance and stored in the refrigerator. It can be made 3 months in advance and placed in an airtight container in the freezer. If frozen- thaw the day before by placing in the refrigerator over night. Allow buttercream to sit at room temperature and rewhip in an electric mixer for 5 minutes until light and fluffy.
