Homemade Funfetti Cake Recipe

Okay, confession time: I used to grab the boxed stuff because I thought making a Funfetti cake from scratch sounded, um, suspiciously hard. Turns out, I was completely wrong. This recipe? SO doable. You’re just tossing together basic baking basics. Eggs, flour, butter yada yada. Then you bury the batter in rainbow sprinkles and watch it turn happy.

And here’s the real kicker. You don’t need fancy pans, complicated mixing moves, or a kitchen full of gadgets. Just a bowl, a whisk or electric mixer (I swear by my ten-dollar handheld beat-up one), and, yeah, a craving for something sweet. If buttercream’s your thing, whip up a simple one while the layers cool. Frost, decorate, eat. And if you’re still in the mood for another treat, check out this easy carrot cake recipe at Vox Recipes.

Why You’ll Love This Recipe

First off, this Funfetti cake is pure joy. It’s bright, buttery, and every bite is scattered with those little bursts of colorful sweetness. If you’re like me, you’ll find excuses to make it for birthdays, holidays, Tuesdays doesn’t matter.

Plus, there’s zero weird aftertaste (I cannot do the artificial thing), and it’s so much softer than box mix. You can even freeze extra slices if you don’t eat the whole thing first. And let’s be honest, this cake beats store-bought anything. You can even turn it into cupcakes or a fun layer cake with extra frosting and sprinkles. Haven’t tried frosting in between layers yet? Oh man, life-changing. If you want something fudgier, the chocolate cake recipe at Vox Recipes is a great next bake.

INGREDIENTS FOR THE BEST FUNFETTI CAKE

Here’s what you’re tossing in the bowl. (Don’t sweat, I’ll keep it simple.)

  • 2 and ½ cups all-purpose flour (don’t pack it!)
  • 1 tablespoon baking powder
  • ½ teaspoon salt
  • 1 cup unsalted butter, room temp is best
  • 1 and ½ cups sugar
  • 4 large eggs (pop ‘em out of the fridge early)
  • 1 tablespoon vanilla
  • 1 cup whole milk (trust me on this)
  • ½ cup rainbow sprinkles (the “jimmies” style, not nonpareils!)

For that melt-in-your-mouth finish, try a basic vanilla buttercream. Or grab your fave frosting up to you. I sometimes swipe on a cream cheese frosting if I’m feeling wild. And if you wanna see some wild combos, peek at Mango Mousse Cake Recipe as well.

STEP BY STEP INSTRUCTIONS: HOW TO MAKE CONFETTI CAKE FROM SCRATCH

Start by heating your oven to 350°F. Grease n’ line your cake pans (or a big ol’ 9×13 dish whatever you have).

Mix your dry stuff: flour, baking powder, salt. No need to sift unless you’re feeling fancy. Next, cream your butter and sugar together till it’s nice and soft. Toss in eggs one at a time, beating after each (if you forget, no big deal, just mix them in). Drop in the vanilla.

Now, gently fold in the dry stuff and milk, alternating like a third of the dry, then some milk, repeat till it’s all gone. No need to overthink it, just don’t beat it to death.

Here’s the fun: barely stir in the sprinkles! If you overmix, the colors will run and your cake will look, well, gray and questionable.

Pour into pans, bake about 28-32 minutes for rounds (a rectangular dish might go longer). Toothpick test for the win when it’s clean, you’re golden. Cool totally before frosting, or it’ll melt right off.

And if you think confetti cakes are fun, you’d probably love the neiman marcus cake recipe at Vox.

Sprinkle Success Tips

Want perfect rainbow pockets and not a muddy mess? Here’s the deal:

  • Use the long, “jimmies” style sprinkles. Nonpareils melt and bleed everywhere. (Trust me, I learned the hard way.)
  • Only fold sprinkles in at the end. Quick stir, stop before you feel guilty.
  • Don’t use too many. Half a cup is goldilocks-good the cake will be bright, but not over-the-top. Too much, and you’ll end up with crunchy weirdness.
  • Test sprinkles by dropping a few in water. If they instantly bleed, pick a different brand.

Feeling wild? Swap in festive shapes or bright colors for different holidays! I add red and green for Christmas, orange and purple for Halloween. Try making a Cloud Cake if you wanna go super fluffy here’s one at Vox Recipes!

Pro Tips For Making This Recipe

Alright, real talk baking is half following the rules and half trusting your gut. Just don’t skip the “room temp butter” thing, because cold butter will never cream right and your cake won’t be that dreamy-soft texture.

Also, do taste your sprinkles before throwing in the batter. Some are weirdly waxy, others are magic. I love the classic crunchy type, but you do you.

If you’re layering, freeze the cake layers for 30 minutes before stacking them that makes frosting way less stressful. You can totally add a layer of jam (think strawberry for a fun twist). Speaking of things that wow, if cheesecake’s more your speed, this deliciously creamy Basque cheesecake is epic.

“This recipe brought me back to my childhood birthday parties and was a total showstopper at our family BBQ. My best friend begged for the recipe. I’ll never buy the boxed mix again!” Tara L.

For breakfast lovers, the banana cottage cheese pancakes at Vox are a wild (and tasty) start to the day.

Common Questions

Can I double this Funfetti Cake recipe for a big party?

Absolutely! Just use two pans and maybe add five minutes to baking time. Test with a toothpick.

Help! My sprinkles melted, what did I do wrong?

Probably used nonpareils or mixed too long. Try “jimmies” and add them just before baking.

Can I make Funfetti cupcakes with this?

Yes, and they’re adorable. Scoop batter into lined muffin tins and bake about 18-20 minutes.

Do I need to chill before frosting?

It helps, but if you’re in a rush, let it cool on the counter. Warm cake + frosting = sliding disaster.

What’s the best frosting?

Vanilla buttercream’s a classic, but cream cheese is always a win. I even tried chocolate surprisingly good! For inspiration, check churro cheesecake at Vox too.
