Dot Cake Recipe

What Is a Dot Cake?

A dot cake is a fun, sprinkle-covered cake that has become popular online for its simple but eye-catching look. The "dots" usually come from colorful round sprinkles pressed or scattered over frosting, giving the cake a bright, playful finish.

My version is a little different because I made it as a mason jar dot cake recipe. Instead of stacking full cake layers, I cut or crumble the vanilla cake into small pieces and layer it with buttercream frosting right inside small jars. Then I finish each jar with a thick swirl of frosting and lots of rainbow dot sprinkles. It is easy, cute, and honestly such a fun dessert to make with kids!

Ingredients for Dot Cake in a Jar

For this mason jar dot cake recipe, you only need a few simple ingredients.

For the Vanilla Cake

Use one batch of your favorite vanilla cake recipe. I used a soft vanilla cake inspired by RecipeTin Eats' vanilla cake method, then baked it, cooled it completely, and layered it into jars.

You can use:

• Homemade vanilla cake
• Boxed vanilla cake mix
• Store-bought vanilla cake
• Leftover birthday cake
• Vanilla cupcakes

The key is making sure the cake is fully cooled before layering, so the frosting does not melt.

For the Buttercream Frosting

• 1 cup unsalted butter, softened
• 3 ½ to 4 cups powdered sugar
• 2 teaspoons vanilla extract
• 2 to 4 tablespoons milk or heavy cream

For Decorating

• Rainbow dot sprinkles
• Small mason jars
• Piping bag or zip-top bag

How to Make Dot Cake Recipe in Mason Jars

Step 1: Bake the Vanilla Cake

Start by baking your vanilla cake according to the recipe instructions. I like using a soft, fluffy vanilla cake because it pairs perfectly with the buttercream and sprinkles.

Once baked, let the cake cool completely. This is really important because warm cake will make the frosting melt and slide around in the jars.

Step 2: Make the Buttercream Frosting

In a large bowl, beat the softened butter until smooth and creamy. Add the powdered sugar a little at a time, mixing well after each addition.

Add the vanilla extract, salt, and 2 tablespoons of milk or cream. Beat until light and fluffy. Add more milk or cream as needed until the frosting is smooth and easy to pipe.

Step 3: Cut or Crumble the Cake

Once the cake is fully cooled, cut it into small circles that fit inside your mason jars. You can use a round cookie cutter, the rim of a glass, or simply crumble the cake into pieces.

I personally love a slightly rustic layered look because it feels homemade and sweet.

Step 4: Layer the Cake and Frosting

Add a layer of vanilla cake to the bottom of each mason jar. Pipe or spoon a layer of buttercream frosting on top.

Repeat with another layer of cake and another layer of frosting until the jar is almost full.

Step 5: Add the Dot Sprinkles

Finish each jar with a generous layer of buttercream frosting on top. Then cover the frosting with rainbow dot sprinkles.

This is what gives the dessert that viral dot cake look!

Step 6: Chill or Serve

You can serve the dot cake jars right away, or place the lids on and store them in the fridge until you are ready to enjoy.

If chilling, let the jars sit at room temperature for about 10-15 minutes before serving so the cake and frosting soften slightly.

Tips for Making the Best Dot Cake Recipe

Let the Cake Cool Completely

Do not rush this step. If the cake is even a little warm, the buttercream can melt and the layers may not look as pretty.

Use Small Mason Jars

Small jars work best because this dessert is rich and sweet. I like using 4-ounce or 8-ounce mason jars depending on the occasion.

Pipe the Frosting for Pretty Layers

You do not need a fancy piping tip, but using a piping bag or zip-top bag with the corner snipped off makes the layers cleaner and easier to control.

Add Sprinkles Right Before Serving

If you want the sprinkles to stay bright and crisp, add them shortly before serving. Some sprinkles can bleed color into frosting if they sit too long.

Make It Your Own

This dot cake recipe is super easy to customize. You can use pink sprinkles for a baby shower, pastel sprinkles for Easter, red and green for Christmas, or school colors for a classroom treat.

Fun Variations

Birthday Dot Cake Jars

Add a birthday candle to each jar right before serving for the cutest individual birthday cakes.

Pink Dot Cake

Use pink buttercream and pink sprinkles for a soft, girly version that would be so pretty for a baby shower or tea party.

Chocolate Dot Cake

Use chocolate cake instead of vanilla cake and top with colorful dot sprinkles for a fun chocolate birthday cake jar.

Confetti Dot Cake

Fold rainbow sprinkles into the vanilla cake batter before baking, then add dot sprinkles on top for an extra colorful funfetti-style version.

Mini Party Favor Cakes

Add lids, ribbon, and a little tag to turn these mason jar cakes into adorable party favors.

How to Store Dot Cake Jars

Store the assembled dot cake jars covered in the refrigerator for up to 3 days.

For the best texture, let them sit at room temperature for a few minutes before serving. This helps the buttercream soften and makes the cake taste fresh and fluffy again.

I would not recommend freezing the fully assembled jars with sprinkles, since the sprinkles may bleed color as they thaw. If you want to prep ahead, freeze the cake separately and assemble the jars closer to serving time.

Can I Make This Dot Cake Recipe Ahead of Time?

Yes! This is one of my favorite things about this recipe.

You can bake the cake one day ahead, make the frosting ahead, and assemble the jars the day you plan to serve them. You can also fully assemble the jars the night before and store them in the fridge.

For the prettiest look, add the final sprinkle topping right before serving.

What Size Mason Jars Should I Use?

I recommend using 4-ounce jars for smaller portions or 8-ounce jars for a larger dessert.

The 4-ounce jars are perfect for kids' parties, dessert tables, or party favors. The 8-ounce jars feel more like a full individual cake serving and are great for birthdays or special treats.
