Ingredients
For a batch of Mango Oatmeal Crumble Bars, you will need:
1 ½ cups rolled oats (150 g)
1 cup all-purpose flour (125 g)
¾ cup brown sugar (150 g), packed
½ tsp baking powder (2 g)
¼ tsp salt (1 g)
¾ cup unsalted butter (170 g), melted
2 cups fresh or frozen mango chunks (about 300 g), pureed
2 tbsp honey or maple syrup (30 ml)
1 tsp vanilla extract (5 ml)
Optional: shredded coconut or chopped nuts for topping
The oats and flour form the crumbly, buttery base and topping. Mango puree delivers natural sweetness, while brown sugar enhances flavor. Butter binds the crumble layers, and vanilla adds aromatic depth. Optional toppings offer extra texture and visual appeal.
Pro Tips
Use ripe, juicy mangoes – For the best flavor, select mangoes that are fragrant and yield slightly to pressure. Frozen mangoes work but drain excess liquid to avoid a soggy filling.
Chill the crumble topping – Letting the crumble sit in the fridge for 15–20 minutes before baking helps it hold its shape and prevents it from sinking into the mango layer.
Even layers matter – Spread the mango puree evenly and gently press the crumble on top to create uniform bars that slice neatly.
These tips ensure your bars have a perfect balance of soft, juicy filling and crisp topping, with clean slices that hold together.
Instructions
Step 1
Preheat the oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper, leaving overhang for easy removal.
Step 2
In a large bowl, combine rolled oats, flour, brown sugar, baking powder, and salt. Mix well to distribute dry ingredients evenly.
Step 3
Pour melted butter and vanilla extract into the dry mixture. Stir until the mixture is crumbly but holds together when pressed.
Step 4
Press half of the oat mixture evenly into the prepared pan to form the base. Press firmly but gently to create a compact layer.
Step 5
In a separate bowl, combine mango puree and honey or maple syrup. Spread this mango mixture evenly over the base layer. Smooth the top with a spatula.
Step 6
Crumble the remaining oat mixture over the mango layer. Press lightly to ensure it adheres but still retains a crumbly texture. Add optional toppings such as shredded coconut or chopped nuts.
Step 7
Bake in the preheated oven for 30–35 minutes, until the crumble topping turns golden brown and the mango layer is bubbly.
Step 8
Cool completely in the pan on a wire rack, then refrigerate for at least 1–2 hours to set the bars. Slice into squares or rectangles before serving.
Step 9
Serve chilled or at room temperature. These bars are perfect as a tropical breakfast treat, snack, or dessert, offering a balance of sweet, fruity flavor with a crunchy oat texture.
Variations
Berry Mango Crumble Bars – Add raspberries or blueberries to the mango puree for a tart-sweet twist.
Gluten-Free Option – Replace all-purpose flour with almond or oat flour to make the bars gluten-free.
Nutty Mango Crumble Bars – Incorporate chopped almonds, pecans, or cashews into the crumble for added crunch and flavor.
These variations allow customization based on dietary preferences or seasonal fruit availability.
Storage and Serving
Store Mango Oatmeal Crumble Bars in an airtight container in the refrigerator for up to 4 days. They can also be frozen for up to a month — wrap individual bars in plastic wrap and store in a freezer-safe bag.
Serve bars chilled for a refreshing, firm texture, or warm slightly in the microwave for a soft, gooey mango center. Pair with a scoop of vanilla ice cream for dessert or enjoy as a standalone tropical snack.
