Sugar-free passionfruit sponge

Sugar-Free Passionfruit Sponge
Ingredients
- 2 cups almond flour
- 1/2 cup granulated sweetener (such as Swerve or Erythritol)
- 3 large eggs, separated
- 1/2 cup unsalted butter, melted
- 2 teaspoons vanilla extract
- 1/4 teaspoon salt
- 1 cup passionfruit puree (see notes)
- 1/4 cup chopped fresh passionfruit (optional)
Instructions
- Preheat the oven: Preheat the oven to 350°F (180°C). Grease a 9-inch (23cm) round cake pan.
- Prepare the sponge mixture: In a large bowl, whisk together the almond flour, granulated sweetener, and salt.
- Combine the wet ingredients: In a separate bowl, whisk together the melted butter, egg yolks, vanilla extract, and passionfruit puree.
- Combine the wet and dry ingredients: Add the wet ingredients to the dry ingredients and mix until just combined.
- Beat the egg whites: Beat the egg whites until stiff peaks form.
- Fold in the egg whites: Fold the egg whites into the sponge mixture until no white streaks remain.
- Pour the batter: Pour the batter into the prepared cake pan.
- Bake the sponge: Bake for 25-30 minutes, or until a toothpick inserted into the center of the sponge comes out clean.
- Cool and serve: Allow the sponge to cool in the pan for 5 minutes, then transfer it to a wire rack to cool completely. Top with chopped fresh passionfruit, if desired.
Notes
- To make passionfruit puree, scoop the pulp and seeds from 2-3 passionfruits and blend until smooth. Strain the mixture through a fine-mesh sieve to remove the seeds.
- You can also use store-bought passionfruit puree or passionfruit juice as a substitute.
