The Best Birthday Cake!
Ever since I was little I can remember always requesting a funfetti cake for my birthday. It’s colorful, has a great texture, and for some reason sprinkles always made it taste so much better.
It was & still is one of my favorites! It’s been a few years since I’ve had it, so this time I decided it was time to make a homemade version- 100% from scratch. And guess what? It’s even better than the boxed kind! It was oh SO good indeed.
Bonus? I can control the ingredients inside, and add any little flares I’d like to…such as extra sprinkles or a variety of sprinkle shapes!
How to Make Funfetti Cake
Making cake from scratch can sometimes be intimidating, but throw it into a 9×13-inch pan and somehow it’s a breeze. Am I right? Seriously though, you’ve totally got this! You’ll need a handful of sprinkles, nothing fancy, just colorful jimmies, along with cake flour, and high quality vanilla extract. Grab a large mixing bowl and a hand mixer (or a stand mixer) and you’re set!
MIX. For the base, you’ll want to start by beating the sugar, butter, vanilla extract and almond until they’re light and fluffy. Then add the eggs and egg white, and mix until combined. In a small mixing bowl sift the all-purpose flour, cake flour, baking soda, baking powder and salt.
COMBINE. With mixing speed on low, gradually alternate adding the dry ingredients along with the buttermilk. Mix just until combined, then fold a half cup of sprinkles by hand.
BAKE. Pour into a lightly greased baking pan and bake for 25-30 minutes or until golden brown on top.
FROSTING. While the cake is cooling whip up the frosting. It’s really quick, easy and sooo fluffy!! Start by creaming the butter, then add the vanilla extract, salt and powdered sugar. Mix until large crumbs form, then add the heavy cream and beat until light and extremely fluffy, about 2 minutes.
Buttermilk Substitute: Buttermilk helps to produce a really tender crumb, but If you don’t have any on hand, you can create a substitute. Combine 1 TB of either white vinegar or lemon juice with 1 cup of milk, and let it set for at least 5 minutes. Make sure you use the 1:1 ratio, even though this recipe doesn’t require a full cup of buttermilk!
The Frosting & Sprinkles
I absolutely LOVE using Sweetapolita Sprinkle mixes, which is what I used for these photos. Aren’t they gorgeous?! Of course, you can use simple Rainbow Jimmy Sprinkles, or switch up the color for different occasions!
Just stay away from nonpareils (the little balls) because the color will bleed into the batter and not be very pretty!
I love to use these sprinkles in other “funfetti” recipes, like:
- Funfetti Birthday Cake Blondies
- Funfetti Sugar Cookies
- Patriotic Funfetti Cupcakes
- Vanilla Funfetti Cupcakes
- Soft Frosted Sugar Cookie Bars
Making Ahead and Storing
Make ahead? You can make your frosting up to a day ahead time and keep tightly covered in the fridge. In terms of the cake you will want to make it during the day before frosting and serving it that night. Let the cake cool completely before frosting!
Store: We recommend that you store this cake covered at room temperature for up to 3 days.
Freeze: To freeze the cake, let it cool completely out of the pan(consider baking extra cakes in round pans, they’re easier to get out than a 9×13 pan) and then double wrap it in plastic. Then wrap the cake in foil to assure that you don’t get freezer burn on your cakes! Leave it in the freezer for up to 3 months. Thaw it in the fridge for at least 8 hours to thaw completely before decorating and serving.
