Instructions

1. Prep your 8×8-inch baking pan by lining it with parchment paper. Set your oven to 350°F and give the pan a quick spray of nonstick cooking spray for extra insurance.
2. Grab a large mixing bowl and combine 1 ½ cups oats, 1 ¼ cups flour, ½ cup granulated sugar, ½ cup brown sugar, 1 teaspoon baking powder, and ¼ teaspoon salt. Mix these dry ingredients thoroughly.
3. Add ½ cup softened butter, 1 large egg, and 1 teaspoon vanilla extract to your dry mixture. Use your hands to blend until the dough feels crumbly but can hold together when squeezed. Set aside 1 cup of this mixture for your topping.
4. In another bowl, toss 1 ½ cups cranberries with ¼ cup honey until the berries are evenly coated and glistening.
5. Press the remaining dough firmly into the bottom of your prepared pan, creating an even base layer that covers the entire pan surface.
6. Spread the cranberry mixture across the dough, ensuring an even distribution of berries from corner to corner.
7. Sprinkle the reserved 1 cup of crumble mixture over the cranberry layer, letting some chunks remain larger for a rustic texture.
8. Slide the pan into the preheated 350°F oven and bake for 42-45 minutes, watching for a golden-brown top and bubbling edges.
9. Remove the pan and let the bars cool completely at room temperature for at least 2 hours, which helps them set and makes cutting easier.
10. Once cooled, lift the bars out using the parchment paper and slice into 9 perfect squares using a sharp knife.

Notes

• Always use fresh or frozen cranberries for the best flavor and texture in the crumble bars.
• Press the crust mixture firmly into the pan to create a solid base that won’t crumble when cutting.
• If your cranberries are particularly tart, adjust the honey or maple syrup to balance the sweetness to your preference.
• For a gluten-free version, swap the all-purpose flour with a gluten-free flour blend and ensure your oats are certified gluten-free.
