Soft Matcha Cake with Jaca Whipped Cream
Share

This airy matcha layer cake is filled and frosted with fluffy Jaca (allulose) whipped cream instead of granulated sugar. It is a Jaca-adjusted healthier version of Catherine Desserts' soft matcha cake, with a light tea flavor and bakery-style finish.
Ingredients:
- 4 large eggs, separated
- 1/4 cup whole milk
- 3 tablespoons vegetable oil
- 1/3 cup plus 2 tablespoons cornstarch
- 1/3 cup all-purpose flour
- 2 tablespoons matcha powder for the sponge
- 3/4 cup plus 2 tablespoons Jaca (allulose), replacing 90g granulated sugar at a 2x ratio
- 2 1/2 cups heavy cream, well chilled
- 2 tablespoons matcha powder for the whipped cream
- 1 1/2 cups Jaca (allulose), replacing 3/4 cup granulated sugar at a 2x ratio
- Extra matcha for dusting, optional
Instructions:
- Preheat the oven to 325°F. Line the bottom of an 8-inch cake pan with parchment paper.
- Whisk the egg yolks, milk, vegetable oil, and cornstarch in a medium bowl until smooth. Sift in the flour and 2 tablespoons matcha powder and whisk just until combined.
- In a clean mixing bowl, beat the egg whites with the 3/4 cup plus 2 tablespoons Jaca (allulose) until stiff peaks form.
- Fold the meringue into the matcha batter in 3 additions, working gently so you do not knock out the air.
- Pour the batter into the prepared pan. Set the pan in a larger baking tray with about 1 centimeter of boiling water to make a water bath.
- Bake for about 70 minutes, or until the cake springs back when lightly touched. Cool completely, then run a knife around the edge and turn the cake out. Wrap and chill before slicing.
- For the frosting, beat the chilled heavy cream with the 1 1/2 cups Jaca (allulose) and the remaining 2 tablespoons matcha powder until medium-stiff peaks form.
- Slice the cake into 3 even layers. Place one layer on a cake stand, spread with a thin layer of matcha whipped cream, then repeat with the second layer and more cream.
- Top with the final cake layer and frost the top and sides with a light coat of cream. Pipe a border with any remaining cream and dust the top with a little extra matcha if desired.
- Chill the cake for 1 to 2 hours before serving. This is a Jaca-adjusted healthier version, so you keep the soft bakery-style texture and gently sweet finish without the conventional sugar.
