Hojicha Roll Cake (Printable)

Fluffy roasted green tea sponge rolled with aromatic hojicha cream and fresh mango strips for a stunning Japanese-inspired dessert.

# What You Need:

→ Sponge Cake

01 - 4 large eggs, separated
02 - 5.6 oz granulated sugar, divided
03 - 2 fl oz whole milk
04 - 1.7 fl oz vegetable oil
05 - 2.5 oz cake flour, sifted
06 - 0.35 oz cornstarch
07 - 1 tablespoon roasted green tea powder (hojicha)
08 - 0.25 teaspoon salt

→ Hojicha Cream

09 - 6.8 fl oz heavy cream (minimum 35% fat), chilled
10 - 2 tablespoons powdered sugar
11 - 2 teaspoons roasted green tea powder (hojicha)

→ Filling

12 - 1 ripe mango, peeled and sliced into thin strips

# How To Make It:

01 - Preheat oven to 340°F. Line a 9 x 13 inch baking tray with parchment paper.
02 - In a large bowl, whisk separated egg yolks with 2.8 oz granulated sugar until pale and creamy. Add milk and vegetable oil, mixing until smooth.
03 - Sift together cake flour, cornstarch, hojicha powder, and salt. Fold into the yolk mixture until just combined, being careful not to overmix.
04 - In a clean bowl, beat egg whites until foamy. Gradually add remaining 2.8 oz sugar and continue beating until stiff peaks form.
05 - Gently fold meringue into yolk-flour mixture in three additions, preserving the airiness of the batter to ensure proper rise.
06 - Pour batter into prepared tray and smooth the surface evenly. Tap the tray gently on the counter to release trapped air bubbles.
07 - Bake for 13 to 15 minutes until the cake springs back when lightly pressed with a fingertip, indicating proper doneness.
08 - Remove from oven while still warm and invert cake onto a fresh sheet of parchment paper. Carefully peel off baking paper and cover loosely with a clean kitchen towel. Allow to cool completely.
09 - Whip chilled heavy cream with powdered sugar and hojicha powder until medium-stiff peaks form, creating a stable filling.
10 - Spread hojicha cream evenly over the cooled sponge surface. Arrange mango strips along one short edge of the cake.
11 - Using parchment paper as a guide, gently roll the cake from the edge containing mango, forming a tight spiral. Wrap in parchment and refrigerate for at least 30 minutes until set.
12 - Trim the ends for a neat presentation and slice into portions. Serve at room temperature or chilled as preferred.

# Expert Advice:

01 -
  • It's deceptively elegant: People think you spent hours in the kitchen, but the magic happens in barely thirty minutes of hands-on time.
  • The hojicha flavor is honest: You taste real roasted tea, not a faint echo of it, which makes every bite feel intentional and Japanese.
  • It's forgiving: Even if your roll isn't picture-perfect, the taste carries you through.
02 -
  • Don't skip the parchment swap when inverting: I learned this the hard way—without fresh parchment on top, the warm cake sticks to the tray and tears when you flip it.
  • Hojicha powder quality matters tremendously: Cheap powder tastes bitter and muddy; splurge on good stuff from a Japanese market, and your entire cake changes.
  • The meringue fold is where most cakes fail: Deflate it and you lose height; overmix and you lose the tender crumb—gentle pressure and a rotating bowl are your friends.
03 -
  • If your sponge cracks when you invert it, don't panic: Let it cool a full minute longer and try peeling the paper more slowly, lifting one corner at a time rather than ripping it away.
  • Mascarpone mixed into the cream (replacing half the heavy cream) creates a lighter, tangier filling: I discovered this by accident when a friend with dairy sensitivity asked if I could adjust it, and now I make it both ways.
  • The hojicha-cream ratio is perfect at 2 tsp powder per 200 ml cream: Less and it disappears; more and it becomes bitter—this balance took several tests to nail.
