I’ve been testing birthday dessert ideas for my granddaughter’s third birthday party and fell in love with this recipe. These little jars went straight to the top of the list. Everyone gets their own cake, so there’s nothing to slice once the party starts. They’re just as welcome at a Halloween party, since this is one monster the kids run toward.

Ingredients needed to make Cookie Monster Dot Cakes.

CAKE MIX – I use a 15.25-ounce box of Duncan Hines Devil’s Food, and Betty Crocker Super Moist works too. Brands change their egg, oil, and water amounts now and then. Go by the back of your box if it differs from the card.

CHOCOLATE FROSTING – One 16-ounce tub fills all 12 jars, with a spoonful or two to spare. Give it a good stir first, and it spreads smooth and levels easily.

BLUE SPRINKLES – Grab the tiny round sprinkles, sold as nonpareils, in any shade of blue. For the shimmery look in the photos, pick up pearlized ones or small sugar pearls at a craft store. A full cup gives you a deep bed for easy dipping.

CANDY EYEBALLS – Grab the large size, so the faces show up from across the party table. You’ll find them in the baking aisle near the sprinkles. Leftover eyes are just right for these Halloween Monster Eye Pretzels from xoxoBella.

MINI CHOCOLATE CHIP COOKIES – Mini Chips Ahoy! and bite-size Famous Amos are both the right size for the mouth. You only need 12, so the rest of the bag is the cook’s reward.

Leftovers and Storage

STORE – Cover the jars and keep them at room temperature for up to 3 days. A cake carrier or a deep container with a lid protects the faces. They look their best the day you decorate them.

FREEZE – Freeze the filled and frosted jars, without sprinkles or faces, for up to 1 month. Cover each jar tightly with a lid or plastic wrap. Thaw on the counter, then dip and decorate.

REHEAT – Serve these cakes at room temperature. They need no reheating.

MAKE AHEAD – Fill and frost the jars the day before, then cover them and leave them on the counter. Dip the tops in sprinkles and add the faces before the party.

Serving Suggestions

BIRTHDAY PARTY – Set the jars on a cake stand and let them stand in for cupcakes. Those googly eyes look so cute next to Unicorn Oreo Pops on a kids’ dessert table.

HALLOWEEN PARTY – A friendly monster suits little trick-or-treaters and trunk or treat tables. I’d set out Halloween Cheesecake Bars for the grown-ups.

BAKE SALE – Single-serve jars are easy to price and easy to hand over. A batch of four-ingredient Cool Whip Cookies fills out the table.

MILK AND COOKIES NIGHT – Serve the jars with cold milk and a plate of Chocolate Chip Cookies. It’s the sweetest little way to end a family movie night.

Recipe Success Tips

LEVEL TOPS – A flat, full top picks up sprinkles from edge to edge. Fill the frosting right to the rim, then sweep a knife straight across. If a cake round sits low in the jar, press in a few cake scraps before frosting.

SPRINKLE BOWL – Use a small bowl that is just a little wider than the jar. The sprinkles stay deep, so one firm press covers the whole top.

LEFTOVER CAKE – The jars use about half the cake, and the rest is a bonus dessert. Crumble it with frosting and roll it into Cake Pops. Or grab a second tub of frosting and fill extra jars for the cook.

LITTLE ONES – For toddlers, swap the hard sprinkles for soft blue jimmies and skip the candy eyes.

Expert Tip – To make the box mix taste homemade, add one extra egg and swap the water for milk. Then use melted butter in place of the oil. Keep the milk and butter amounts the same as the box calls for.

Commonly Asked Questions

What Is a Dot Cake?

A dot cake is a single-serving cake in a cup or jar, topped with frosting and covered in tiny round sprinkles. The sprinkles are the dots. A mother-daughter bakery on Long Island created the original, and it went viral in the spring of 2026. This version adds a friendly blue monster face.

Can I Make Cookie Monster Dot Cakes Ahead of Time?

Cookie Monster Dot Cakes hold up beautifully when you make them a day ahead. Fill and frost the jars, cover them, and leave them on the counter overnight. Dip the tops in sprinkles and add the eyes and cookies shortly before the party. The faces look their freshest that way.

What Can I Use Instead of Mason Jars?

Clear 4-ounce plastic dessert cups work just as well as glass jars. They’re lighter to carry, and they’re a smart choice for a party full of small kids. Pick sturdy cups, since the rim is your cake cutter. Small paper cups work too, though you lose the view of the cake layers.

Can I Use a Different Cake Mix?

Yes, any flavor and any size of boxed cake mix works here. Both the 13.25-ounce and 15.25-ounce boxes fit a 9×13 pan. Vanilla, yellow, and funfetti are all fun for a birthday. I recommend keeping the chocolate frosting so the blue sprinkles stand out. A from-scratch 9×13 cake works too, like this Gluten Free Chocolate Sheet Cake from Seasonal Cravings.

How Do I Turn These Into Halloween Monster Dot Cakes?

Change the sprinkle color and the number of eyes, and you have a whole tray of Halloween monsters. Green, purple, and orange nonpareils all work the same way as the blue. Mix a few colors on one platter for a trunk or treat or a class party. Here are a few easy faces to start with.

Monster	Sprinkles	Face
Cookie Monster (this recipe)	Blue	2 large candy eyes, mini cookie mouth
One-eyed monster	Green	1 large candy eye in the center
Three-eyed monster	Purple	3 candy eyes in a row
Pumpkin monster	Orange	2 candy eyes, candy corn nose
