Full Recipe: 

Ingredients

For the Crust and Crumble Topping:

  • ½ cup unsalted butter, melted

  • 1 cup all-purpose flour

  • ¾ cup old-fashioned rolled oats (don’t use quick-cooking oats)

  • ½ cup granulated sugar

  • ¼ cup light brown sugar, packed

  • ½ teaspoon salt (or to taste)

For the Mango Layer:

  • 2 cups coarsely chopped fresh ripe mango (or frozen, thawed and drained)

  • ⅓ cup granulated sugar

  • 2 tablespoons lemon juice

  • 2 teaspoons cornstarch

Directions

  1. Prepare the crust and crumble topping:
    Preheat the oven to 350°F (175°C). Line an 8-inch square baking pan with aluminum foil and spray with cooking spray for easy removal. In a large microwave-safe bowl, melt the butter, about 1 minute. Stir in the flour, oats, sugars, and salt until the mixture is crumbly and sandy. Set aside 1 cup of the mixture for the crumble topping. Press the remaining mixture into the prepared pan to form the crust.

  2. Make the mango layer:
    In the same bowl, add the chopped mango, sugar, lemon juice, and cornstarch. Toss everything together to combine, ensuring the mango is well-coated.

  3. Assemble the bars:
    Evenly spread the mango mixture over the crust in the pan. Sprinkle the reserved crumble topping over the mango layer.

  4. Bake:
    Bake for 50 to 55 minutes, or until the edges are set, and the crumble topping is golden. The mango layer may bubble around the edges.

  5. Cool and serve:
    Allow the bars to cool for at least 1 hour in the pan before slicing and serving. For best results, let them fully cool to avoid them falling apart. Enjoy!

The Flavorful Mango Filling

The mango layer is the heart of these bars, providing a burst of tropical sweetness that stands out against the buttery crust and oatmeal crumble topping. Mangoes are naturally sweet and juicy, with a vibrant color and fragrant aroma that makes them an irresistible fruit to use in desserts. In this recipe, the mango is coarsely chopped and combined with a bit of sugar, lemon juice, and cornstarch, which helps thicken the mixture and create a cohesive filling that holds together nicely once baked.

Mangoes are rich in vitamins, particularly vitamin A and vitamin C, making them a nutritious addition to any dish. Vitamin A supports eye health and immune function, while vitamin C helps with collagen production and the body’s ability to absorb iron. Additionally, mangoes are high in antioxidants, which help protect the body from oxidative stress and contribute to overall health. By using fresh, ripe mangoes in this recipe, you not only enhance the flavor but also provide a healthy component to the dessert that’s both refreshing and satisfying.

The Buttery Oatmeal Crust and Topping

The crust and crumble topping of these bars are made from a simple mixture of butter, oats, flour, and sugar, creating a rich, buttery base with just the right amount of sweetness. The oats add a wonderful chewiness to the bars, providing texture that contrasts beautifully with the soft mango filling. The sugar gives the crust a subtle sweetness, while the brown sugar adds a hint of molasses flavor that complements the oats and butter.

This oatmeal-based crust is easy to prepare, requiring just a few simple ingredients that come together quickly to form a crumbly, sandy mixture. Pressing the mixture into the pan creates a firm base that holds the mango filling in place, while the remaining topping is sprinkled over the mango layer, creating a crunchy, golden finish once baked. The result is a satisfying bite with layers of flavor and texture that will keep you coming back for more.

The Ease of Preparation

One of the main appeals of Mango Oatmeal Crumble Bars is how simple they are to prepare. With just a few steps and minimal ingredients, you can have a delicious homemade treat ready to enjoy in less than an hour. The crust and crumble topping come together easily, and the mango filling requires little more than tossing the fruit with a bit of sugar and lemon juice.

Once the layers are assembled, the bars bake in the oven for around 50 minutes, during which time the ingredients meld together, creating a golden, crisp topping and a bubbly, fragrant mango layer. The most challenging part of this recipe is allowing the bars to cool before slicing, as the sweet smell of the baking mango filling can make it tempting to dive right in. However, letting the bars cool for at least an hour ensures that the filling sets properly and that the bars hold together when sliced, making them easier to enjoy.

A Versatile Treat for Any Occasion

These Mango Oatmeal Crumble Bars are incredibly versatile, making them perfect for any occasion. They can be served as a sweet breakfast option, paired with a cup of coffee or tea for a relaxing morning. The natural sweetness of the mango and the chewy texture of the oats make them a satisfying start to the day. Alternatively, they can be enjoyed as a mid-afternoon snack, offering a wholesome treat that is both filling and satisfying without being overly indulgent.

These bars also make an excellent dessert for a casual gathering or a family get-together. Their sweet, tropical flavor makes them a perfect summer treat, but they can be enjoyed year-round. The individual servings are easy to serve, making them great for picnics, brunches, or potlucks. Whether you’re entertaining guests or enjoying a quiet afternoon at home, Mango Oatmeal Crumble Bars are a delightful and easy option that everyone will enjoy.

The Nutritional Benefits of Mangoes and Oats

Mango Oatmeal Crumble Bars offer not only a delicious flavor but also several nutritional benefits. Mangoes are a rich source of vitamins, especially vitamin C and vitamin A, both of which contribute to a healthy immune system, skin, and vision. They are also packed with antioxidants, which help reduce inflammation and protect the body’s cells from damage.

Oats, another key ingredient in this recipe, are a whole grain that is high in fiber, particularly soluble fiber, which has been shown to help lower cholesterol levels and regulate blood sugar. Oats are also a good source of protein, vitamins, and minerals, including B vitamins, iron, and magnesium. The fiber content in oats helps promote digestion and keeps you feeling fuller for longer, making these bars a filling and nutritious snack or dessert option.

By combining mangoes and oats in this recipe, you get a flavorful treat that offers not only a satisfying taste but also a variety of health benefits. These bars are a great way to incorporate more fruit and whole grains into your diet, while still enjoying a sweet treat.

A Customizable Recipe

One of the best things about Mango Oatmeal Crumble Bars is their flexibility. While the recipe calls for fresh mangoes, you can easily substitute them with other fruits if mangoes are out of season or if you prefer a different flavor. Peaches, berries, or even apples can be used in place of mangoes, offering a variety of options depending on your taste preferences.

Similarly, the crust and crumble topping can be adjusted to suit your dietary preferences. For a gluten-free version, you can substitute the all-purpose flour with a gluten-free flour blend, ensuring that everyone can enjoy this treat. The sweetness of the bars can also be adjusted to your liking, whether you prefer a more decadent dessert or a lighter snack. You can also add nuts or seeds to the crumble topping for extra texture or flavor, making these bars a truly customizable treat.

Storing and Serving Tips

Mango Oatmeal Crumble Bars store well in an airtight container, making them perfect for meal prep or leftovers. They can be kept at room temperature for a few days or refrigerated for a longer shelf life. If you want to enjoy them chilled, simply store them in the fridge and allow them to come to room temperature before serving. They also freeze well, so you can make a batch ahead of time and freeze them for later.

These bars are delicious on their own, but they can also be served with a dollop of whipped cream, a scoop of vanilla ice cream, or a drizzle of caramel sauce for an extra indulgent treat. For a more health-conscious option, you can enjoy them with a scoop of yogurt or a handful of fresh fruit for a lighter dessert.

Conclusion

In conclusion, Mango Oatmeal Crumble Bars are a delightful and versatile dessert that combines the natural sweetness of mangoes with the rich, nutty flavor of oats and the satisfying texture of a buttery crumble topping. Whether you’re looking for a quick breakfast, a satisfying snack, or a light dessert, these bars offer a perfect balance of flavors and textures that will appeal to everyone. They are easy to make, customizable, and packed with nutritional benefits, making them a wholesome and delicious addition to your recipe collection. Whether served warm or chilled, Mango Oatmeal Crumble Bars are sure to become a go-to treat for any occasion.
