Viral Dot Cake
These viral dot cakes are the individual sprinkle-coated mini cakes taking over TikTok - rounds cut from a funfetti sheet cake, heavily frosted, then pressed top-down into rainbow nonpareils so the top is completely covered in dots. We tested it three times, and the change that made it actually work was freezing the sheet cake for about 30 minutes before cutting the rounds - cold cake releases in one clean piece instead of crumbling apart. They look like a bakery showstopper, but they start with a box of cake mix, which is exactly why they went viral.

What Is a Dot Cake?
A dot cake is a small, individual round of cake topped with a dense layer of tiny round sprinkles - the "dots." The viral version starts with a funfetti sheet cake (so there are sprinkle dots baked inside too), which gets chilled, cut into rounds, frosted, and pressed top-down into nonpareils. Each round is served in its own little cup, so instead of one large cake you slice, you end up with a batch of individual sprinkle-topped cakes - perfect for parties, and the reason they photograph so well. The trend started at a New York City bakery - Dot Cakes, made popular at Butterfield Market on the Upper East Side - whose colorful little sprinkle-covered cups blew up on TikTok. That sent everyone scrambling to recreate them at home, which is exactly what we did here.
Why You'll Love Them
- Start with a box mix. No scratch baking required - the trend works because anyone can make it.
- Individual portions. Each guest gets their own little cake; no slicing or serving needed.
- Big visual impact. A dense sprinkle top reads as bakery-level, especially for a kids' party or birthday.
- Customizable. Tint the frosting and switch the sprinkle color to match any party theme.
Ingredients You'll Need
- Funfetti cake mix - one standard box (about 15.25 oz), plus the eggs, oil, and water it calls for. A plain vanilla mix with a half cup of nonpareils stirred into the batter works too.
- Vanilla buttercream - we used a quick homemade buttercream instead of store-bought; it's easy and, to us, tastes noticeably better (recipe in the card below).
- Mini nonpareils - 1 to 2 cups of the tiny round sprinkles (sometimes labeled hundreds and thousands). These hold their color best; see the tips on why we avoid jimmies and sanding sugar.
- Food coloring (optional) - a few drops to tint the frosting; we made ours pink.
- Small serving cups - we set each finished cake in a little cup for serving (the ones in the photos have a gold trim).
How to Make Viral Dot Cakes
Here is the full step-by-step. The process photos slot in at each step.
Step 1: Make the batter and bake. Combine the funfetti cake mix with the eggs, oil, and water from the box directions and whisk until smooth. Spread the batter into a parchment-lined rectangular sheet pan and bake per the box, then let it cool completely.
Step 2: Freeze the cake. Pop the cooled cake into the freezer for about 30 minutes. This firms it up so the rounds release cleanly - skipping it is the number-one reason the cake crumbles when you cut into it.
Step 3: Cut out the rounds. Press dessert cups, ramekins, small mason jars, or a large biscuit cutter straight down into the chilled cake and lift. The round comes out inside the cutter. We used 8 oz cardboard soup-style containers, but anything round and sturdy works - just remember the cutter size sets how many cakes you get.
Step 4: Make the buttercream. Beat the butter until soft and fluffy, beat in the vanilla, then slowly add the confectioners' sugar until combined. Add the milk a little at a time if it's too stiff, and tint with a few drops of food coloring if you like - we made ours pink.
Step 5: Cup and frost. Frost the top of each cake round generously with buttercream. A thick, even top coat is what the sprinkles press into; a thin layer leaves bald patches.
Step 6: Press into the sprinkles. Pour the mini nonpareils into a wide, shallow bowl. Tip each frosted cup over and press the buttercream top straight down into the sprinkles until the whole top is evenly coated, then turn it upright.
Step 7: Serve. That's it - a batch of individual dot cakes, ready to go. They're at their best the day they're made.
Variations
- Cutter size sets the yield. Small 4 oz mason jars make about 12 little cakes; larger ramekins give you around 6 bigger ones. Pick the size for your crowd.
- Colored frosting. A few drops of food coloring tints the buttercream - we made ours pink, and it looks great peeking through the sprinkles.
- Themed sprinkle colors. Use a single-color nonpareil mix to match a party: pastels for a baby shower, red and green for the holidays.
- Cake flavor. Plain vanilla or yellow cake mix work if you'd rather skip the funfetti; stir in nonpareils for the baked-in dots.
👩🍳 Tips from My Kitchen
We made these three times to get them right, and almost everything that improved them came down to temperature and sprinkle choice. Here's what actually mattered.
- Freeze the cake 30 minutes before cutting. This was our biggest fix - cold cake releases from the cutter in one clean round, while room-temperature cake crumbles and tears.
- Your cutter sets the yield. Small 4 oz mason jars gave us about 12 little cakes; a larger ramekin makes around 6. A large biscuit cutter works too, and the freezing is what keeps those edges clean.
- Frost the top heavily. A thick, even coat of buttercream on top is what the sprinkles press into - a thin layer leaves bald patches.
- Use mini nonpareils, not jimmies or sanding sugar. We tested all three. The rod-shaped jimmies and coarse sanding sugar bled their color into the frosting; the tiny round nonpareils stayed crisp and bright far longer.
- Tint the frosting for contrast. A few drops of food coloring in the buttercream - we went pink - gives a pretty color peeking through the sprinkle coating.
- Serve them the day you make them. Even with nonpareils, some color softens over time, so these are best coated close to serving.
FAQs
What can I use to cut the rounds?
Dessert cups, ramekins, small mason jars, or a large biscuit cutter all work. The cake round lifts out inside the cutter. We used 8 oz cardboard soup-style containers, but anything round and sturdy is fine. The cake can also be served in the cups, jars or ramekins. If you use a biscuit cutter, you can serve the cakes as is or put them in a dessert cup.
How many dot cakes does one sheet cake make?
It depends on your cutter. Small 4 oz mason jars make about 12 little cakes, while larger ramekins give you around 6 bigger ones.
Why do I need to freeze the cake first?
Chilling the cake for about 30 minutes firms it up so the rounds release from the cutter cleanly. Room-temperature cake tends to crumble and tear when you try to cut and lift it.
Do I need to line the pan with parchment paper?
Yes, I'd really recommend it. Lining the sheet pan with parchment keeps the cake from sticking to the bottom, so when you press the cutter down the whole round lifts out cleanly instead of tearing or leaving half of itself stuck in the pan.
What type of sprinkles work best?
Mini nonpareils - the tiny round sprinkles - work best. We found jimmies (the rod-shaped ones) and sanding sugar bled their color into the frosting, while nonpareils stayed crisp and bright.
Can I use a homemade cake instead of a box mix?
Yes. Any sturdy vanilla or funfetti sheet cake works - you just need it firm enough to hold its shape when cut, and freezing it briefly helps either way.
Can I use different colored frosting?
Absolutely. We tinted our buttercream pink with a few drops of food coloring; any color looks pretty peeking through the sprinkle coating.
Can I make them ahead of time?
These are best frosted and coated the day you plan to serve them. Mini nonpareils hold up better than other sprinkles, but the freshest look comes from coating them close to serving.
Can I freeze a dot cake?
Freezing the finished, sprinkle-coated cakes isn't recommended - the sprinkles soften and their colors run once they thaw. (Freezing the plain sheet cake for 30 minutes before cutting is a different step, and one we recommend.)
Viral Dot Cake
Ingredients
For the cake
- 1 box funfetti cake mix about 15.25 oz / 432 g, plus the eggs, oil, and water it calls for (or vanilla mix + ½ cup nonpareils stirred in)
For the buttercream frosting
- ½ cup unsalted butter at room temperature
- 2 cups confectioners' sugar sifted
- 1½ teaspoons pure vanilla extract
- 2 tablespoons milk
For decorating
- 1 –2 cups mini nonpareils the tiny round sprinkles; avoid jimmies and sanding sugar — they bleed
- A few drops of food coloring optional, to tint the buttercream
Instructions
- Bake the funfetti cake in a parchment-lined rectangular sheet pan per the box directions; cool completely.
- Freeze the cooled cake for ~30 minutes so the rounds release cleanly.
- Cut rounds from the chilled cake using dessert cups, ramekins, small mason jars, or a large biscuit cutter (8 oz cardboard soup-style containers used in the photos). Press down and lift; the round comes out in the cutter.
- Make the buttercream: beat the butter until soft and fluffy. Add the vanilla and beat until incorporated. Slowly add the confectioners' sugar, beating until combined. Add milk a little at a time if too stiff; add food coloring if desired.
- Frost each round heavily all over so the sprinkles have plenty to grab.
- Pour the mini nonpareils into a wide, shallow tray or bowl.
- Lightly press each frosted round into the sprinkles, turning to coat all sides, then set on a serving board.
Notes
• Yield depends on cutter size: ~12 small cakes from 4 oz jars, ~6 from larger ramekins.
• Best frosted and coated the day they're served — freshest sprinkle look.
• Mini nonpareils hold color far better than jimmies or sanding sugar, which bleed into the frosting.
• Don't freeze the finished cakes: sprinkles soften and colors run on thawing.
