Step 1

Preheat the oven at 375 deg F and line a baking tray with parchment paper. I used my square 8-inch baking pan. Grease the sides and bottom with coconut oil and set it aside.

Step 2

Add 1.5 cups old-fashioned rolled oats in a mixer jar or blender grind it into a powder. We need 1.5 cups of oat flour, so use rolled oats as needed.

Step 3

Add the chopped cherries, mangoes, corn starch, sugar, and lemon juice to a mixing bowl. Mix well and set it aside.

Step 4

In another mixing bowl, add the coconut oil and the brown sugar and mix well.

Step 5

Now add the remaining ingredients - prepared oats flour, 1/4 cup of the remaining rolled oats, baking powder, baking soda, salt, and vanilla essence.

Step 6

Mix well using a fork, and the crumb mixture will be like below—Reserve 1/3 of this mixture.

Step 7

Now take 2/3 part of this mixture and press it into the bottom of the prepared pan evenly.

Step 8

Spread the cherry mango filling on top evenly.

Step 9

Now sprinkle the remaining crumb mixture on top.

Step 10

Bake it at 375 deg F for 25 minutes or until the top is golden. Remove it from the oven and let it cool completely before slicing. I cut it into 9 square bars.
