Keto bread usually has a base of almond flour and/or coconut flour. Then eggs, baking powder, milk and an oil are added to form the bread. For this gluten free Herbes de Provence bread I also added spices, parmesan cheese and olive oil to give the bread a delicious flavor.  My bread may be a bit more yellow than yours because I used farm fresh duck eggs for this recipe. Duck eggs tend to have a darker yolk than chicken eggs and will give your bread a darker color.
