Preheat your oven: Set the oven temperature to 350°F (175°C). Prepare a 9x9-inch baking dish by lining it with parchment paper, allowing some excess paper to hang over the sides for easy removal after baking.
Mix the dry ingredients: In a large mixing bowl, combine the almond flour, rolled oats, brown sugar, granulated sugar, ground cinnamon, and sea salt. Stir them thoughtfully until well combined.
Incorporate the butter: Add the cold, cubed butter to your dry mixture. Using your fingertips or a pastry cutter, mix the butter into the dry ingredients until the mixture achieves a texture similar to coarse crumbs. Be gentle to maintain some larger pieces for a better crumble texture.
Create the base layer: Take half of the crumble mixture and evenly press it into the bottom of the prepared baking dish. Ensure it forms a solid layer to support the cherry filling.
Prepare the cherries: In a separate bowl, toss the halved cherries with the pure vanilla extract and almond extract, ensuring they are well coated. Distribute the cherry mixture evenly over the base layer, creating a vibrant, fruity filling.
Add the crumble topping: Crumble the remaining oat mixture generously over the cherries. Make sure to cover them evenly, as this will form a delicious, crisp topping.
Sprinkle with almonds: For an added layer of crunch, sprinkle the sliced almonds evenly over the crumble topping, enhancing both texture and flavor.
Bake: Place the baking dish in the oven and bake for about 30-35 minutes. You're looking for a golden brown top with bubbles forming around the cherries, indicating they’re all warm and juicy.
Cool and cut: Once baked, allow the bars to cool completely in the baking dish. Use the overhanging parchment paper to lift the bars out. Cut into squares or rectangles to serve.
Notes
Dust the bars lightly with powdered sugar for an elegant touch. Serve garnished with fresh cherries or a sprig of mint.
