A shortbread recipe typically includes just three main ingredients: butter, sugar, and flour. To make shortbread, start by creaming the butter and sugar together until light and fluffy. Then, gradually mix in the flour until a soft dough forms. Once the dough is ready, shape it into a rectangle or press it into a baking pan. Cut it into squares or fingers before baking. Bake in a preheated oven at 350°F (175°C) for about 20-25 minutes, or until the edges are lightly golden. Allow to cool before enjoying this classic treat!
