1/2 cup melted butter
1 tsp vanilla powder
2 cups chopped rhubarb
2 tbsp powdered erythritol (for topping)

Instructions

Preheat your oven to 350°F (175°C). Grease a 9-inch round cake pan and line the bottom with parchment paper.
In a bowl, mix the chopped rhubarb with lemon juice and 1 tbsp powdered erythritol. Spread evenly at the bottom of the prepared pan.
In another bowl, whisk together almond flour, erythritol, baking powder, and salt.
Add eggs, melted butter, and vanilla powder to the dry ingredients. Mix until well combined.
Pour the batter over the rhubarb layer in the pan, spreading it evenly.
Bake for 35-40 minutes, or until a toothpick inserted in the center comes out clean.
Let the cake cool for 10 minutes, then invert it onto a serving plate. Remove the parchment paper carefully.
Serve warm or at room temperature. For more dessert ideas, visit fogonyfuego.

Make sure to let the cake cool slightly before inverting to prevent it from breaking.
Store leftovers in an airtight container in the fridge for up to 3 days.

FAQ

Can I use frozen rhubarb?

Can I substitute almond flour with coconut flour?

Coconut flour absorbs more liquid, so you’ll need to adjust the quantity. Use 1/3 cup coconut flour and add an extra egg.

Is this cake freezer-friendly?
