If you want to cook for celiac people you have to be really careful 'cause everything you touch with the ingredients cannot be contaminated by elements that contain gluten. Be careful and clean everything well before start cooking!
Ingredients
♦ 85g of flour (the type depends on if you want to do it without gluten or not)
♦ 170g of chocolate
♦ 113g of butter
♦ 250g of sugar
♦ 5g of baking soda or (gluten free) yeast
Steps
First and the most important part is (if you cook for a celiac person) as I said before, cleaning well all you're going to cook in. After that and preparing the ingredients you can preheat the oven at 175ยบ. Then you have to crack the chocolate and melt it applying by parts the butter. I did it on a little saucepan so I had to be really careful and be stirring all the time because chocolate gets burnt easily, so watch out!
