We cut the puff pastry in equal squares, we put non-stick paper on a baking dish and we spread out the puff pastry squares, we hit them with a fork and we sprinkle them with a little sugar. We bake at 180 degrees Celsius for about 15 minutes or until they get a light brown color. In a saucepan we put the water, oat drink, sugar, vanilla and lemon juice. We put on moderate heat and as soon as it starts to boil, we add semolina, while stirring continuously with a wire. We remove from the heat, we add agave syrup, coconut oil and we mix well. We cover the cream with a membrane along the surface and we let it cool in the refrigerator. Once it’s cold, we hit it well with the hand blender. In each puff pastry we put 4 to 5 tablespoons. cream, we put another piece of puff pastry and another layer of cream, we close it with another piece of puff pastry and we sprinkle with powdered sugar.
