These muffins are really just the eggless quiche recipe converted into a quiche cake recipe. The recipe is exactly the same (remember to omit bacon and cheese for vegan/dairy-free) but I just omit the pastry. I add 150 g of gluten-free self-raising (cake) flour to the mixture before cooking in muffin trays until brown and cooked through. They freeze and reheat well in the microwave. For the eggless quiche recipe it’s here.
