Follow these easy steps to make your incredible Cranberry Crumble Bars:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 9×9-inch baking pan.

2. Prepare Cranberry Filling: In a medium saucepan, combine the cranberries, granulated sugar, cornstarch, lemon juice, and vanilla extract. Cook over medium heat for about 5-7 minutes until the cranberries start to soften and release their juices. Stir occasionally.

3. Make the Crust and Crumble: In a large bowl, whisk together the flour, baking powder, salt, and brown sugar. Cut in the cold butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Stir in the rolled oats.

4. Press the Base: Take about 2/3 of the crumble mixture and press it firmly into the bottom of the prepared pan to create a base.

5. Add Cranberry Filling: Spread the prepared cranberry mixture evenly over the crumbled base.

6. Top with Remaining Crumble: Sprinkle the remaining crumble mixture on top of the cranberries. Ensure it’s evenly distributed.

7. Bake: Place the pan in the preheated oven and bake for 40-45 minutes, or until the top is golden brown.

8. Cool the Bars: Remove from the oven and allow the bars to cool in the pan for about 15-20 minutes before cutting them into squares.

9. Serve Warm or Cold: These bars can be served warm, or you can let them cool completely before serving.

By following these steps, you can create delectable Cranberry Crumble Bars that will impress anyone who tries them.
