Ingredient Notes
Cake Flour-For a soft and tender cake texture, cake flour is the best flour to use. I would not substitute cake flour for any other flour or you will change the texture of the cake.
Leavening Agent-This cake only needs baking powder to allow the cake to rise and have a fluffy texture.
Butter-Unsalted butter melted and cooled will be mixed in to the batter and the course of fat for this cake.
Sugar-Granulated sugar will sweeten the cake the perfect amount.
Buttermilk-Give this cake the most delicious flavor and creates a super moist texture. I would not recommend substituting buttermilk for any other milk. If you don't have buttermilk you can use whole milk and lemon juice to make your own buttermilk.
Sour Cream- Sour cream and buttermilk add a great flavor to this snack cake. You can replace the sour cream for full fat greek yogurt if you don't have sour cream on hand.
Sprinkles- Rainbow jimmies are the best to mix into the cake batter. I would not use the nonpareils in the batter because the color tends to bleed.
Cream Cheese-Full fat cream cheese is going to give the frosting a thick texture and rich flavor.
Butter-Unsalted butter at room temperature!
How To Make The Best Funfetti Snack Cake
Prepare The Cake Batter
In a large bowl combine the melted butter, granulated sugar, eggs, vanilla extract, buttermilk and sour cream; whisk until smooth and ingredients are fully combined
Add in the flour, baking powder and salt; whisk until smooth and creamy
Fold the rainbow sprinkles into the cake batter and mix until fully combined
Line and Bake The Cake
Prepare a 9 inch square cake pan with melted butter or pan spray and line with parchment paper
Spread the cake batter into the cake pan and bake at 350 degrees f for 18-20 minutes or until the cake bounces back at the touch or a cake tester comes out clean.
Prepare The Frosting
While the cake is baking, prepare the Vanilla Cream Cheese Frosting or Vanilla Buttercream Frosting and set aside until the cake is cooled
Allow the cake to cool completely before spreading the frosting on top of the cake
Homemade Funfetti Sprinkle Mix
You can use a store bought sprinkle mix or make your own! I love the different colors, textures and sizes of a variety of sprinkles mixed together. Rainbow jimmies, nonpareils and confetti sprinkles are a great combination that will make this cake extra festive and fun!
Decorate and Serve
Decorate the top of the cake with your homemade sprinkle mixture and allow the frosting to set for 10 minutes before cutting and serving!
For a clean cake cut, refrigerate the cake for 5 minutes to allow the icing to set. Dip your knife in hot water, wipe the water off and cut the cake into nine squares. Repeat this step for each slice to make sure that each piece is nice and neat!
Tips and FAQS To Make The Best Funfetti Snack Cake
Room Temperature Ingredients
It is very important when baking a cake to have all your ingredients at room temperature. This will ensure that all ingredients gets mixed together evenly!
There are so many ways to cut a cake, but I love to chill the cake for 10 minutes and then use a warm knife to slice the cake. Make sure to clean the knife with hot water in between each slice to remove the crumbs from the knife and have clean slice.
