Make the best-ever Funfetti Birthday Cake including my Master Funfetti Cake recipe and best-ever buttercream frosting recipe.
Servings: 12 serving
Ingredients
- 3 ⅓ cups (1lb 1oz/ 500g) all purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- ½ teaspoon salt
- 1 ½ cups (12oz/355g) granulated sugar
- 1/2 cup (3 oz / 90g) light brown sugar
- 1 cup (8oz / 240g) butter, melted
- 2 Large eggs
- 2 cups (16oz / 500g) Buttermilk
- 1 tablespoon vanilla extract
- 2/3 cup (3oz/90g) sprinkles
Buttercream Frosting - 1 cup (8oz/240g) butter, softened to room temperature
- 3 cups (12oz/360g) powdered sugar, sifted
- 2-3 drops of Green food colouring (use what ever color you like)
Instructions
- Preheat oven to 350F(180oC) degrees. Grease and line a 2x 9-inch springform or baking pan.
- In a large bowl, mix together flour, both sugars, baking powder, baking soda, and salt. Set aside.
- In a large microwave-safe bowl, melt butter in the microwave.
- In a separate jug, whisk the egg, buttermilk, and vanilla extract until combined.
- Stir in buttermilk mix into the dry ingredients, followed by the butter until no lumps remain. The batter will be thick.
- Lastly, stir in sprinkles, but do not overmix because the sprinkles will bleed their color.
- Pour batter into prepared cake pan. Bake for 35-40 minute or until a toothpick inserted in the center comes out clean. Allow to cool.
- To make the frosting, beat softened butter on medium speed with an electric or stand mixer. Beat for 3 minutes until smooth and creamy. Add powdered sugar, and flavoring (bubble gum or vanilla extract) with the mixer running. Increase to high speed and beat for 3 minutes.
- Frost cooled cake: Start by frosting a thin ‘crumb layer’. Chill for 30 minutes to set the frosting. Once that layer is set apply a second layer of thicker frosting
- Using a butter knife, pressing gently run it from the bottom to the top all the way around. You will create lovely, rough texture. Continue on the top of the cake moving from the edge of the cake to the center.
- Decorate as desired with candy and sprinkles. There may be leftover frosting depending how much you wish to use.
- Cover cake and store at room temperature for up to 7 days. Enjoy!

Hi Gemma! This is the first time I followed a YouTube recipe and it came out AMAZING. Thank you soo much for sharing ❤
Hi Gemma, I’m planning to make this recipe soon. However, 2 pans is too many. Do you have a recipe for one 9-inch pan? I understand it’s not good to just halve this recipe. Thanks!
Hi!
i just tried your best ever chocolate cake with chocolate fudge frosting and it was AMAZING!!! Super easy to make and super delicious too!
I have some leftover frosting so I was thinking I’ll make this cake and use the chocolate fudge frosting…it will taste good right?
A BIG thanks for all your amazing and easy recipies!!
Hi Gemma which butter do you recommend salted or unsalted for the cake and buttercream?
Thanks
Hi Gemma,
In the video you have mentioned that this recipe is your yellow cake recipe.And also the same recipe that you use for rainbow cake.But there’s an extra ingredient in your rainbow cake recipe which is sour cream. I was wondering which one’s better for a basic yellow cake, the rainbow cake recipe or the funfetti one. Please reply asap.I want to make this for my mom’s birthday on 6th June.

Stay safe gemma
Hi, Gemma. ???? can i reduce the sugar? I don’t use substitutes when baking. I just reduce the amount of sugar. What is the maximum amount that i can take away from the recipe? It has both granulated and brown. Thank you so much! I’m planning to make this for my daughter’s birthday. Take care.
Hi Jemma, I’m planning on making this cake for a birthday and I was wondering if I can spilt the batter over three 7’’ cake tins. Would this work?
Hi Gemma, I am planning to make this cake for my Husband and daughters birthday this weekend. However due to the current situation, I am unable to source all-purpose flour from anywhere 🙁
Can i use Plain flour instead or any other flour?
Gemma can you share some flavors of unique birthday cakes?
