How to Make Buttery Cranberry Streusel Crumb Bars
-
Preheat and Prepare: Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish. This ensures your lovely bars release easily after baking.
-
Mix Cranberries: In a bowl, combine the fresh cranberries with 1 cup of granulated sugar; set aside. This allows the cranberries to soak up the sugar and become wonderfully sweetened.
-
Cream Butter and Sugar: In a mixing bowl, cream together the softened butter and remaining sugar until fluffy. Add eggs one at a time, then gently mix in the flour until just combined for a smooth base.
-
Make the Streusel: For the streusel, mix flour, brown sugar, cinnamon, and cold butter together until the mixture is crumbly. This creates a deliciously crunchy topping that contrasts perfectly with the soft filling.
-
Layer the Fillings: Spread half of the base mixture into the prepared dish, layer it with the cranberry filling, and then top with the streusel. This layering creates delicious bites of both sweet and tart.
-
Bake: Place the dish in the preheated oven and bake for 40-45 minutes or until the top is golden brown. Allow cooling before cutting them into bars—this helps them hold their shape.
Optional: Dust with powdered sugar for a sweet finishing touch.
