A butter tart is a classic Canadian dessert that features a flaky pastry shell filled with a sweet, gooey mixture primarily made of butter, sugar, and eggs. The filling can vary, often including ingredients like raisins, pecans, or walnuts, which add texture and flavor. Butter tarts are typically baked until the filling is set but still slightly runny in the center. Originating in Ontario, butter tarts have become a beloved treat across Canada. They are often served warm and can be enjoyed on their own or with a scoop of ice cream. The simplicity of the ingredients and the ease of preparation contribute to their popularity in home baking.
