Ube Roll Cake: The Softest Purple Swiss Roll You'll Ever Make
A pillowy ube chiffon cake rolled with lightly sweetened ube whipped cream - bakery-level beautiful, surprisingly simple.
Roll cakes are one of the most satisfying desserts to make. The cake-to-cream ratio is ideal: every bite delivers a mouthful of fluffy sponge and silky filling. Add ube powder to the equation and you get a naturally vibrant purple cake with a sweet, hazelnut-vanilla aroma that's impossible to resist.
This recipe uses a chiffon cake base - lighter and more flexible than a standard sponge - so it rolls up without tearing. No stabilizers, no artificial colors, just real ube flavor throughout.

Why Ube Roll Cake Is Worth Making
If you've ever had a Japanese-style roll cake from an Asian bakery, you know the appeal: impossibly light sponge, just enough cream, and a clean spiral that looks professional. Ube makes this format even better. The natural purple color creates a stunning visual contrast with the lighter cream filling, and the hazelnut-vanilla flavor of ube pairs beautifully with whipped cream.
Unlike layer cakes that require stacking, crumb-coating, and frosting, a roll cake is baked in one flat sheet and assembled in minutes. The chiffon method - separating eggs and folding whipped whites into the batter - produces a cake that's both airy and sturdy enough to roll without splitting.
The purple color comes entirely from anthocyanins in the ube, the same antioxidants found in blueberries and purple grapes. So your showstopping dessert is also packed with natural plant compounds.
Ube Roll Cake Ingredients
Ube Chiffon Cake
- 5 large eggs, separated
- 1/4 tsp cream of tartar
- 140g granulated sugar (95g + 45g)
- 55g whole milk
- 45g neutral oil (canola or grapeseed)
- 2 tbsp ube powder + 2 tbsp warm water (mixed into a paste)
- 1 tsp vanilla extract
- 115g cake flour, sifted
Ube Whipped Cream
- 380g cold whipping cream (min. 30% fat)
- 35g powdered sugar
- 1 tbsp ube powder + 1 tbsp water (mixed into a paste)
- 1/2 tsp vanilla extract
Ube Roll Cake: Step-by-Step Instructions
Step 1: Prep your ube cake pan
Preheat the oven to 350F (175C). Line a 12x17 inch rimmed baking sheet with parchment paper on the bottom only - do not grease the sides. The cake needs to cling to the edges to rise properly.
Step 2: Whip the ube meringue
Separate the egg whites and yolks into two large bowls. Add cream of tartar to the whites and beat with an electric mixer on medium speed until foamy. Gradually sprinkle in 95g of sugar, one tablespoon at a time. Continue beating until you reach stiff peaks - the meringue should hold its shape when you lift the beaters.
Step 3: Make the ube yolk batter
To the egg yolks, add 45g sugar, milk, oil, the ube powder paste, and vanilla. Whisk until smooth. Sift in the cake flour and mix until just combined - don't overmix. The batter should be a vibrant purple.
Step 4: Fold and pour the ube batter
Add about one-third of the meringue to the yolk batter and fold gently to lighten it. Then add the remaining meringue and fold until no white streaks remain. Be gentle - you want to keep as much air as possible. Pour into the prepared pan and spread evenly with an offset spatula.
Step 5: Bake the ube chiffon
Bake for 12-13 minutes. The cake is done when the edges are lightly golden and the surface springs back when gently pressed. Slightly overbaking is better than underbaking - an underdone chiffon will deflate and become dense.
Step 6: Flip and pre-roll the ube cake
Let the cake cool in the pan for exactly 5 minutes. Run a spatula around the edges. Place a wire rack on top, flip, and remove the pan. Peel off the parchment paper. Place a fresh sheet of parchment on the cake, flip again so the nice side faces down. Starting from one short end, roll the cake up with the parchment paper inside. Let it cool completely in this rolled shape - this "trains" the cake to hold its curve.
Step 7: Whip the ube cream filling
In a large cold bowl, combine the whipping cream, powdered sugar, ube powder paste, and vanilla. Beat on low-medium speed until the cream thickens to firm peaks. Don't over-whip or it will become grainy.
Step 8: Fill and roll the ube cake
Carefully unroll the cooled cake. Spread the ube whipped cream in a generous, even layer across the surface, leaving about 5cm (2 inches) of bare cake at the far end. Starting from the short end nearest to you, roll the cake back up tightly (without the parchment this time). Use an offset spatula to clean up any cream that squeezes out.
Step 9: Chill and slice the ube roll
Wrap the roll tightly in plastic wrap, twisting the ends to seal. Chill in the refrigerator for at least 3 hours (overnight is ideal). Before serving, trim about 1cm off each end to reveal the beautiful spiral. Slice into 8 even pieces with a sharp knife.
Step 10: Decorate the ube roll cake
For a professional finish, reserve some ube whipped cream and transfer it to a piping bag fitted with a star tip. Pipe decorative rosettes along the top of the roll. You can also dust lightly with powdered sugar or add a few fresh berries for color contrast.
