Ingredients

Crust and Crumble Topping
  • Ā½ cup unsalted butter melted
  • 1 cup all-purpose flour
  • Ā¾ cup old-fashioned whole-rolled oats donā€™t use quick cook or instant, theyā€™re finer and behave like flour and will make the mixture too dry
  • Ā½ cup granulated sugar
  • Ā¼ cup light brown sugar packed
  • Ā½ teaspoon salt or to taste
Mango Layer
  • 2 cups coarsely chopped fresh ripe mango I used fresh ataĆŗlfo mango; frozen mango may be substituted, thaw fully and drain excess liquid before using
  • ā…“ cup granulated sugar
  • 2 tablespoons lemon juice
  • 2 teaspoons corn starch

Instructions

    Cup of Yum
  1. Preheat oven to 350F. Line an 8-inch square pan with aluminum foil and spray with cooking spray; set aside. Lining the pan helps with cleanup and is recommended.
  2. Crust and Crumble Topping - In a large, microwave-safe bowl melt the butter, about 1 minute on high power.
  3. Add the flour, oats, sugars, optional salt, and stir to combine. Mixture will be dry and sandy with some larger, well-formed crumble pieces.
  4. Set 1 heaping cup mixture aside to be sprinkled on later as crumble topping.
  5. Transfer remaining mixture to prepared pan, and using a spatula or your fingers, hard-pack the mixture to create an even, smooth, flat crust; set aside.
  6. Mango Layer - In a largeĀ mixing bowl (same one used for crust and crumble is okay), addĀ all ingredients and toss to combine. If sugar hasnā€™t dissolved fully thatā€™s okay because it liquifies while baking.
  7. Evenly distribute mango mixture over theĀ crust.
  8. Evenly sprinkle with the reserved heaping 1 cup crumble topping mixture. Before sprinkling, I squeeze the mixture in my palm to encourage bigger crumble pieces to form.
  9. Bake for about 50 minutes, or until edges are set and center has just set. Crumble topping should appear set and very pale golden and the mango filling mixture may be bubbling along the edges. BarsĀ mayĀ take longer than 50 to 55 minutes if the mangos are very juicy. Watch your bars, not the clock, when evaluating doneness.
  10. Place pan on a wire rack and allow barsĀ to cool for at least 1 hourĀ before slicing and serving. If you try to slice bars before theyā€™ve cooled completely, theyā€™ll be extremely messy and could fall apart.Ā Bars will keep airtightĀ at room temperature for up to 1 week, in the fridge for up to 10 days, orĀ in the freezer forĀ up to 6 months.

Notes

  • Storage: Seal the bars tightly in plastic wrap, and store them at room temperature for up to 1 week or in the refrigerator for up to 10 days. The bars also freeze well and will last up to 6 months if sealed tightly in a freezer bag or freezer-safe container.Ā
