This Easy Bubble Up King Cake Recipe is the simplest way to make a festive Mardi Gras dessert at home. Refrigerated cinnamon-roll dough is cut into pieces, coated with melted butter, brown sugar, cinnamon, and pecans, then baked in a generously greased Bundt pan for 30–35 minutes.
The result is a golden, pull-apart cake with warm cinnamon flavor, buttery brown-sugar syrup, crunchy pecans, and sweet icing. Decorated with purple, green, and gold sugar, it serves 10–12 people and takes about 55–65 minutes from start to finish, including cooling and decorating.

A traditional king cake can involve yeast, rising time, shaping, and careful decorating. This shortcut version uses canned cinnamon rolls, so the dough is ready to cut and bake with very little preparation.
Each piece pulls away from the ring easily, making this a relaxed dessert for a Mardi Gras party, brunch, classroom celebration, or family breakfast. The Bundt pan gives the cake its classic ring shape while the cinnamon-roll dough creates soft layers throughout.
The flavor is rich but familiar. Brown sugar and butter melt around the dough as it bakes, cinnamon adds warmth, pecans bring crunch, and the included icing supplies just enough sweetness to finish the cake.
If you are planning a full New Orleans-inspired spread, serve this dessert after a savory meal and add a batch of homemade beignets for another festive treat.
Ingredients You’ll Need
The ingredient list is short, but each item has an important job. Use two cans of refrigerated cinnamon rolls, approximately 12.4 ounces each, and keep the icing that comes in the packages for decorating.
- Cinnamon rolls: These provide the dough, built-in cinnamon filling, and a convenient icing packet.
- Unsalted butter: Melted butter coats the dough and helps form the glossy brown-sugar syrup.
- Light brown sugar: Its molasses flavor creates a caramel-like coating as the cake bakes.
- Ground cinnamon: A teaspoon intensifies the warm spice flavor.
- Pecans: Finely chopped pecans add a pleasant contrast to the soft dough.
- Colored sugar: Purple, green, and gold or yellow sugar provide the recognizable Mardi Gras finish.
The optional confectioners’ sugar, milk or cream, and vanilla extract are useful if you want more glaze than the cinnamon-roll packages provide. A small plastic king-cake baby is also optional, but it must be added after baking.

How to Make It Step-by-Step
Step 1: Heat the oven to 350°F. Generously grease a 10- or 12-cup Bundt pan, taking special care around the center tube, bottom, sides, and every decorative crevice because the brown-sugar syrup can cling as it bakes.
Step 2: Open the cinnamon-roll cans and separate the rolls. Cut every roll into quarters so the pieces are small enough to spread throughout the Bundt pan and create the characteristic pull-apart texture.
Step 3: Add the melted unsalted butter, packed light brown sugar, and ground cinnamon to a bowl. Stir until combined, then fold in the finely chopped pecans so the nuts are coated in the buttery mixture.
Step 4: Toss the quartered dough pieces with the butter mixture, using a gentle hand so the pieces do not become compressed. Alternatively, layer dough pieces and spoonfuls of the butter mixture directly in the prepared pan, distributing the pecans as evenly as possible.
Step 5: Place the dough in the Bundt pan without pressing it down tightly. Loose pieces have room to expand, which helps the cake bake into a light, bubbly ring instead of a dense mass.
Step 6: Bake for 30–35 minutes, checking toward the end of the baking window. The cake should be puffed and golden brown, and the dough in the center should look cooked through rather than pale or wet.
Step 7: Let the cake cool in the pan for approximately 5–10 minutes. This brief rest allows the syrup to settle while the cake remains warm enough to release more easily than it would after cooling completely in the pan.
Step 8: Place a serving plate over the Bundt pan and carefully invert the cake. If a few pecans or syrup remain in the pan, scrape them out and spoon them over the exposed cake for extra flavor.
Step 9: Drizzle the icing supplied with the cinnamon rolls over the warm or cooled cake. If you want a larger or thinner glaze, whisk together 1/2 cup confectioners’ sugar, 1–2 tablespoons milk or cream, and 1/2 teaspoon vanilla extract, adding the liquid gradually.
Step 10: Sprinkle the purple, green, and gold or yellow decorating sugars over the wet icing in separate bands or a casual pattern. If using a king-cake baby, hide it underneath the cooled cake or place it in the cake just before serving; never bake a plastic baby inside the cake.
For a full party menu, a pan of crispy roasted potatoes can provide a simple savory side before dessert. The cake itself is ready in about 55–65 minutes when prep, baking, cooling, and decorating are included.
Pro Tips for the Best Bubble Up King Cake
Grease generously. A light coating is not enough for a Bundt pan. Use plenty of butter or baking spray and make sure the center tube is covered, since sticky syrup often gathers there.
Do not pack the dough. Whether you toss the pieces in a bowl or layer them in the pan, keep them loose. This gives the dough room to puff and keeps the finished cake tender and easy to pull apart.
Watch the baking time. The cake should be golden and set but still soft. Overbaking can make the cinnamon-roll pieces dry, while removing it too early can leave the center undercooked.
Cool briefly before unmolding. Five to ten minutes is usually enough. A long rest in the pan may allow the syrup to become sticky and make release more difficult.
Decorate while the icing is wet. The colored sugars adhere best immediately after the icing is drizzled. Add the colors in distinct sections for a classic Mardi Gras appearance or scatter them in small festive stripes.
Adjust the pecans to taste. The recipe uses 1/2 cup finely chopped pecans, but you may omit them or increase the amount to 3/4 cup if your family enjoys a nuttier cake. Chop them finely so they distribute throughout the pull-apart pieces.
Serving, Storage, and Party Ideas
Serve the Bubble Up King Cake slightly warm or at room temperature. Use a serrated knife to cut the ring into portions, or let guests pull apart individual pieces for a casual buffet presentation.
The cake is especially good with coffee, chicory coffee, milk, or hot tea. Since the icing and colored sugar provide the visual decoration, place the cake on a plain white or gold platter so the purple, green, and gold colors stand out.
Keep leftovers covered at room temperature for up to two days. Because the dough is soft and the icing can become sticky, store the cake in a covered container rather than leaving it exposed on the counter.
If you want to prepare part of the menu ahead, make the cake close to serving time for the best texture. A fruit-filled option such as our easy peach bread can also be baked ahead and sliced for a second dessert table choice.
For a savory contrast at brunch, consider adding an easy ham and pineapple salad. Its sweet-tangy flavor works nicely alongside the buttery cinnamon cake without requiring much last-minute preparation.
Common Questions
Can I use biscuit dough instead? Some shortcut versions use two tubes of refrigerated biscuit dough with a separate powdered-sugar glaze. This recipe is written for refrigerated cinnamon-roll dough, which adds built-in cinnamon flavor and includes icing.
Can I mix everything in one bowl? Yes. Gently toss the quartered dough pieces with the butter, brown sugar, cinnamon, and pecans, then transfer the mixture to the pan. Layering is also effective and can help distribute the syrup in smaller pockets.
When should I add the baby? Add the plastic baby only after the cake has baked and cooled. You can hide it underneath the cooled cake or place it into the cake just before serving, but it should never go into the oven.
How do I know the center is done? Look for dough that is puffed, golden, and cooked through in the center of the ring. If the top browns quickly but the interior still appears doughy, allow it to continue baking within the stated 30–35 minute range while watching closely.
