Ingredients
Method
- Preheat your oven to 350°F (175°C). Line a loaf pan with parchment paper or grease it lightly with butter.
- In a large bowl, mix lupin flour, erythritol, baking powder, cinnamon, and salt until well combined.
- In a separate bowl, whip the egg whites and cream of tartar until stiff peaks form.
- In the dry mix, add egg yolks, melted butter, and vanilla extract. Mix until smooth and creamy.
- Gently fold one-third of the whipped egg whites into the batter to lighten it. Gradually fold in the rest, preserving as much air as possible.
- Pour the mixture into the prepared loaf pan, smoothing the top. Bake for 30 minutes or until golden and a knife comes out clean.
- Remove from the oven and let sit for 10 minutes. Then transfer to a wire rack to cool completely.
- Once cooled, slice into 12 pieces and serve as desired.
Notes
For best results, use room temperature ingredients and choose a high-quality lupin flour with a clean flavor. Flavor variations such as herbs or cheese can be added to the base mix. Toast slices to enhance texture.
