It was my husband's birthday over the weekend.
And that meant one thing - Funfetti. I don't have anything against boxed cake mixes.
In fact, I have great recipes that begin with a box.
But, since it was his birthday, I wanted to come up with a homemade version.
After all, Funfetti is basically just a sweet white cake with sprinkles.
I ended up with a tender, white cake that was dotted with sprinkles, and it only took about 5 extra minutes to make!
So, if you have a Funfetti lover at your house, give the homemade version a try, and you may never buy the boxed kind again.
How to make funfetti cake from scratch
Before you begin, it's important to let the butter, egg whites, and buttermilk come up to room temperature.
In a large mixing bowl, beat the butter and sugar together until well-combined.
Add the egg whites and vanilla, and mix in until well-combined.
Be sure to scrape the sides of the bowl as you go.
Add the dry ingredients, and stir in until mostly combined.
Add the buttermilk, and mix in until the batter is smooth.
Stir in the sprinkles.
I recommend stirring them in by hand.
Electric mixers can break the sprinkles up more than hand-stirring will.
Pour the batter into the prepared pan.
Bake until a toothpick somes out with just a crumb or two attached.
The crumbs should look like cake crumbs, not batter.
Tips for make homemade funfetti cake
- Some sprinkles work better than others. I've had good luck with the Betty Crocker rainbow sprinkles because they hold their color well and don't just disappear into the cake.
- If you want to keep the cake as white as possible, use clear vanilla extract in the cake.
- It's important that the cold ingredients (butter, buttermilk, egg whites) be at room temperature to allow them incorporate into the batter. Using cold buttermilk, butter, and eggs can cause lumps in the batter.
Frostings that go well with this cake
The whipped buttercream frosting is light and fluffy and not too sweet.
The vanilla buttercream frosting is a traditional American buttercream frosting.
