Healthy Yule Log Cake

For the sponge

• 4 whole eggs
• 120g oat flour (or whichever flour you normally use)
• 1 teaspoon baking powder
• Vanilla extract

For the filling

• 90% dark chocolate
• 300g light Greek yogurt or mascarpone
• A few drops of liquid sucralose

For the coating

• 90% dark chocolate

Method

1. 1Preheat the oven to 180ºC.
2. 2Add all the sponge ingredients to a blender and blend until completely smooth.
3. 3Line a baking sheet with parchment paper and spread the batter out evenly across the entire surface.
4. 4Bake for 10 minutes (or until the sponge is just cooked through).
5. 5Meanwhile, prepare the filling by mixing the Greek yogurt with the sucralose and finely shaved dark chocolate flakes.
6. 6Once the sponge has cooled down, it's time to roll it.
7. 7Gently peel the parchment paper off the sponge sheet and lay it onto a clean piece of plastic wrap.
8. 8Spread the filling mixture evenly over the top.
9. 9Very gently roll the sponge up into a neat cylinder.
10. 10Wrap it tightly with the plastic wrap and place it in the fridge to set.
11. 11In the meantime, bring a pot of water to a gentle simmer and set a heatproof bowl on top to melt the coating chocolate over a double boiler.
12. 12Unwrap the sponge cake, trim the ends diagonally to give it that classic log shape, and set it on a wire rack.
13. 13Cover with the melted chocolate and, before it sets, run a fork along the surface to create realistic bark textures.
14. 14Let it chill and set in the fridge.
15. 15Decorate however you like before serving.
16. 16All set! Time to slice and enjoy this healthy holiday Yule log cake.
