Instructions

Step 1: Preheat oven to 350°F. In a large bowl, combine 1 1/2 cups all-purpose flour, 1 cup rolled oats, 1 tbsp ground cinnamon, 1/2 tsp baking powder, and 1/4 tsp salt.
Step 2: Stir in 3/4 cup melted unsalted butter and 3/4 cup granulated sugar until mixture is crumbly. Reserve 1 cup of this mixture for the streusel topping.
Step 3: Press remaining oat-flour mixture firmly into the bottom of a greased 9x13-inch baking pan to form the crust.
Step 4: In a separate bowl, toss 1 1/2 cups fresh cranberries and 1 cup peeled, diced apple with 1 tbsp lemon juice and 2 tbsp cornstarch until evenly coated.
Step 5: Spread cranberry-apple filling evenly over the crust layer.

Step 7: Bake bars for 40-45 minutes until topping is golden and fruit filling is bubbly. Cool completely before cutting into squares.
