These Birthday Cake Cinnamon Rolls are pure joy swirled up in every bite. I love how they bring a festive twist to a classic breakfast favorite. The cinnamon sugar spirals stay buttery and soft, while the vanilla frosting on top is thick, creamy, and unapologetically sweet. The finishing touch? A generous splash of colorful rainbow sprinkles that instantly make the whole tray feel like a party.

I first made these for a weekend brunch that happened to land on a friend’s birthday, and they were an instant hit. Since then, they’ve become my go-to for celebratory mornings or anytime I want to start the day with something fun and indulgent. They taste like the perfect mashup of cinnamon roll and birthday cake — nostalgic, cozy, and outrageously delicious.

Why You’ll Love These Birthday Cake Cinnamon Rolls

These rolls are a playful upgrade to the classic cinnamon roll, delivering both the nostalgic flavor of funfetti birthday cake and the warmth of freshly baked cinnamon rolls. The dough is soft and fluffy, with a rich cinnamon swirl tucked inside, while the frosting is creamy and packed with cake batter flavor. They’re colorful, comforting, and guaranteed to put a smile on anyone’s face — no candles required.

What Kind of Sprinkles Should I Use?

Go for classic rainbow jimmies for that iconic birthday cake vibe. Avoid nonpareils or sanding sugar, which can bleed into the dough and turn everything a murky color. Jimmies hold their shape and color beautifully, especially when folded into the dough or sprinkled generously on top.

Options for Substitutions

Cake Mix: You can use any yellow or vanilla cake mix to bring in the birthday cake flavor — even a funfetti mix works if you want double the sprinkles!
Frosting: Cream cheese frosting is a delicious swap if you like a tangy contrast to the sweet dough.
Gluten-Free: Try using a 1:1 gluten-free flour blend in both the dough and frosting — the texture will be slightly different but still tasty.
Vegan: Use plant-based butter and milk alternatives, and opt for a vegan frosting brand or make your own with powdered sugar and non-dairy milk.

Ingredients for These Birthday Cake Cinnamon Rolls

All-Purpose Flour: This forms the base of the dough, giving the rolls their structure and chewy softness.
Whole Milk: Warm milk activates the yeast and enriches the dough.
Instant Yeast: Helps the dough rise quickly and gives it a fluffy texture.
Granulated Sugar: Adds sweetness to both the dough and filling.
Salt: Enhances all the flavors.
Eggs: Adds richness and structure to the dough.
Unsalted Butter: Provides moisture, tenderness, and a rich flavor.
Vanilla Extract: Gives that warm, cake-like aroma.
Dry Cake Mix (Vanilla or Funfetti): Blends into the dough and filling to bring that birthday cake flavor.
Brown Sugar: Essential for the gooey cinnamon-sugar filling.
Ground Cinnamon: Classic spice for the swirl.
Rainbow Sprinkles (Jimmies): Adds color and crunch inside and on top.
Cream Cheese: For the tangy, decadent frosting base.
Powdered Sugar: Sweetens the frosting to perfection.
Heavy Cream or Milk: Loosens the frosting to a spreadable consistency.

Step 1: Prepare the Dough

Warm your milk (not hot!) and mix with sugar and yeast. Let it sit for a few minutes until it foams. Then, mix in eggs, melted butter, vanilla, and dry cake mix. Add the flour and salt gradually, kneading until a soft, slightly sticky dough forms. Cover and let rise in a warm place until doubled in size — about 1 hour.

Step 2: Make the Filling

While the dough rises, mix together brown sugar, cinnamon, softened butter, and a few tablespoons of dry cake mix. This creamy filling spreads beautifully and melts into a gooey swirl when baked. Add rainbow jimmies last so they don’t dissolve.

Step 3: Roll and Fill

Roll out the risen dough into a large rectangle (about ¼-inch thick). Spread the filling evenly, then tightly roll from the long edge into a log. Slice into 12 rolls and place them in a greased or parchment-lined baking dish.

Step 4: Second Rise

Cover the pan and let the rolls rise again for about 30–45 minutes, until puffy and touching. This step is key for soft, pillowy texture.

Step 5: Bake

Bake at 350°F (175°C) for 22–26 minutes, or until the tops are golden and the centers are cooked through. Don’t overbake or they’ll lose their softness.

Step 6: Make the Frosting

Beat softened cream cheese and butter until fluffy. Add powdered sugar, vanilla, a bit of heavy cream or milk, and beat again until smooth. The consistency should be thick yet spreadable — think soft peaks.

Step 7: Frost and Decorate

Frost the rolls while they’re still warm so the frosting melts slightly into the swirls. Then finish with a heavy-handed sprinkle of rainbow jimmies for that true birthday cake finish.

How Long to Prepare the Birthday Cake Cinnamon Rolls

Dough Prep & First Rise: Preparing the dough takes about 20 minutes, and the first rise will require roughly 1 hour. This is when the yeast activates and gives the dough its soft and airy structure.

Assembly, Second Rise & Baking: Rolling, filling, and cutting the dough takes another 20 minutes. Let the rolls rise again for 30–45 minutes, followed by baking for about 22–26 minutes. Frosting and decorating will need an extra 10 minutes, especially if you’re adding sprinkles with care.

Tips for Perfect Birthday Cake Cinnamon Rolls

Use warm, not hot, milk — around 110°F — to activate the yeast properly without killing it.
Don’t skip the second rise; it gives the rolls that bakery-style fluffiness.
Add sprinkles to the filling after mixing to prevent them from bleeding.
Use softened (not melted) butter for the filling to keep it rich and spreadable.
Frost the rolls while warm so the frosting melts just slightly into the rolls for extra gooeyness.

Watch Out for These Mistakes While Cooking

Using hot milk: This can kill the yeast and prevent the dough from rising.
Overbaking: Will dry out the rolls — remove them as soon as they turn golden.
Skipping the rise times: Impatience here will lead to dense, underwhelming rolls.
Using the wrong sprinkles: Nonpareils can melt and discolor the dough; stick with jimmies.
Not kneading enough: Under-kneaded dough won’t develop enough gluten for a chewy, structured roll.

What to Serve With Birthday Cake Cinnamon Rolls?

1. Fresh Fruit Salad

A bowl of mixed berries or citrus balances the sweetness of the rolls with bright, tart notes.

2. Scrambled Eggs or Egg Casserole

Add some protein to the meal to keep things balanced and satisfying.

3. Bacon or Breakfast Sausage

The salty, savory contrast makes the cinnamon rolls shine even more.

4. Yogurt Parfaits

Layered with granola and fruit, yogurt offers creaminess and tang to cut the sugar.

5. Iced Coffee or Latte

The slightly bitter coffee flavor is a perfect match for the sugary richness of the rolls.

Storage Instructions

Room Temperature: If planning to eat within a day, keep the rolls covered at room temperature. The frosting might soften, but the rolls will stay moist.

Refrigerator: Store leftovers in an airtight container in the fridge for up to 4–5 days. Reheat briefly in the microwave before serving to bring back the softness.

Freezer: Freeze unfrosted rolls tightly wrapped for up to 2 months. Defrost overnight in the fridge and warm in the oven. Add frosting and sprinkles just before serving.

Yes! You can prep the rolls the night before and let them rise overnight in the fridge. In the morning, bring them to room temp before baking.

Yes, jimmies are safe to bake and won’t affect texture or taste when added after the filling is made.

Can I use a stand mixer?

Absolutely — use the dough hook and let it knead for about 7–8 minutes until smooth and elastic.
