Not an ounce of butter, sugar and wheat flour! Only useful products! The recipe came from my head. Honestly, when I cooked, I was not sure of the taste, but it was in vain! It's so good... crispy crust with cinnamon flavor, tender and soft banana filling... and only 150 kcal per 100 grams. All losing weight or just watching their health recommend be sure to bake a cheesecake for Breakfast with a Cup of coffee!
