Ingredients
- 6 large eggs, separated (room temperature)
- 1 1/4 cups almond flour
- 1/4 cup coconut flour
- 1/2 cup vanilla protein powder
- 2/3 cup monkfruit powder
- 1/2 tsp salt
- 1 1/2 tsp baking powder
- 1/4 tsp xanthan gum
- 1 large lemon, zested and juiced (approx. 3 tbsp juice)
- 1 tsp vanilla extract
- 2 cups shredded zucchini, squeezed very dry
- 6 tbsp butter, melted and cooled
- 1/2 cup keto-friendly white chocolate chips
How to make it
- Preheat your oven to 350°F (175°C) and line a loaf pan with parchment paper for easy removal.
- In a large bowl, separate the egg whites from the yolks. Beat the egg whites until they form stiff peaks, then set aside.
- In another bowl, combine almond flour, coconut flour, vanilla protein powder, monkfruit powder, salt, baking powder, and xanthan gum. Mix well.
- In a separate bowl, whisk together the egg yolks, lemon zest, lemon juice, vanilla extract, melted butter, and squeezed zucchini.
- Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
- Gently fold in the whipped egg whites to the batter to keep it light and fluffy.
- If desired, add in the keto-friendly white chocolate chips, folding them gently into the mixture.
- Pour the batter into the prepared loaf pan and smooth the top.
- Bake in the preheated oven for 50 to 60 minutes, or until a toothpick inserted in the center comes out clean.
- Allow the bread to cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely.
How to serve it
