Mango Crumb Bars Ingredients
• Enjoy the fresh flavors of Mango Crumb Bars with this simple overview of what you’ll need!
For the Mango Filling
- Mango – About 3 cups diced from ripe mangoes for sweetness and juiciness; frozen or canned mango can work but ensure proper drainage.
- Cornstarch – 2 tablespoons to thicken the mango filling and prevent it from becoming too runny.
- Lemon or Lime Juice – 1 tablespoon, freshly squeezed, to add brightness and complement the mango’s sweetness.
- Vanilla Extract – 1 teaspoon enhances the overall flavor of the mango filling.
For the Crust and Crumble
- All-Purpose Flour – 2 cups, forming the base for both the crust and crumble; substitute with a 1:1 gluten-free blend if desired.
- Granulated Sugar – ¾ cup for sweetness in the crust and topping; adjust based on the sweetness of your mangoes.
- Light Brown Sugar – ¼ cup, packed, for moisture and flavor depth; using all brown sugar makes for softer bars.
- Old-Fashioned Oats – 1 cup for a chewy texture on top; avoid instant oats as they will not yield the same result.
- Baking Powder – 1 teaspoon helps the crumble rise a bit for that perfect texture.
- Fine Salt – ½ teaspoon to balance the sweetness and enhance flavor.
For Binding and Richness
- Unsalted Butter – 1 cup, melted, crucial for richness; can be replaced with coconut oil or vegan butter for a different spin.

Step‑by‑Step Instructions for Mango Crumb Bars
Step 1: Prepare Pan
Begin by preheating your oven to 350°F (175°C), ensuring it’s perfectly hot for baking later. Line an 8 or 9-inch square pan with parchment paper, letting the paper hang over the edges for easy removal later. This little step will save you from a messy cleanup and keeps your Mango Crumb Bars intact!
Step 2: Make Mango Filling
In a mixing bowl, combine your diced ripe mango, ¼ cup of granulated sugar, cornstarch, freshly squeezed lemon juice, and vanilla extract. Toss everything gently until the mango pieces are evenly coated with the sugar and cornstarch mixture. This ensures a deliciously thick filling, preventing your bars from becoming runny.
Step 3: Prepare Crumb Mixture
In a separate bowl, whisk together the all-purpose flour, ¾ cup of granulated sugar, brown sugar, baking powder, and fine salt until combined. Pour in the melted butter and the beaten egg, mixing until the mixture resembles damp sand. This crumb mixture becomes the delightful crust and topping for your Mango Crumb Bars.
Step 4: Assemble
Press two-thirds of the crumb mixture firmly into the bottom of your prepared pan, creating a sturdy base. Carefully spread the prepared mango filling evenly over this crust, ensuring every bite is infused with that juicy mango goodness. Then crumble the remaining crumb mixture on top for a delicious, textural contrast.
Step 5: Bake
Once assembled, place the pan in the preheated oven and bake for 30-42 minutes. Keep an eye on the bars, looking for a golden top and bubbling filling at the edges as a sign they’re ready. The delightful aroma of mango and buttery crumbs will fill your kitchen as they bake.
Step 6: Cool & Slice
Allow your Mango Crumb Bars to cool in the pan for at least 1 hour after baking. For cleaner slices, chill the bars in the refrigerator for another 30-60 minutes. Once cool, use the parchment paper to lift them out of the pan and slice them into squares, revealing the beautiful layers of crust and filling.

Storage Tips for Mango Crumb Bars

Mango Crumb Bars Variations & Substitutions

- Fruit Variation: Substitute some mango with diced peaches or pineapple, keeping the total amount of fruit at 3 cups. This variety adds different textures and flavors, making every bite exciting.
- Sweetener Adjustments: Use maple syrup or honey to replace part of the sugar for a natural sweetness; reduce the butter slightly to balance moisture. Your bars will retain that lovely sweetness while being a tad healthier.
- Dairy-Free Option: Swap out the unsalted butter for coconut oil or vegan butter to make these bars dairy-free. This simple adjustment allows everyone to enjoy the fruity goodness.

Mango Crumb Bars Recipe FAQs
What type of mango should I use for the filling?
Choose ripe, juicy mangoes that yield slightly to pressure for the best sweetness and flavor. If using frozen or canned mango, drain it well to avoid excess moisture which can make the filling runny.
How should I store leftover Mango Crumb Bars?
Store your Mango Crumb Bars in a covered container at room temperature for up to 2 days. If you have leftovers beyond that, refrigerate them in an airtight container for up to 5 days to keep them fresh and tasty.
Can I freeze Mango Crumb Bars, and if so, how?
Absolutely! To freeze, cut the bars into squares and place them in a single layer on a baking sheet. Freeze until solid, about 2 hours, then transfer them to a freezer bag for up to 2 months. To enjoy, thaw in the refrigerator overnight or warm briefly in the microwave.
Why did my crumb topping turn out soggy?
If your crumb topping turned out soggy, it may be due to too much moisture from the mango filling. Make sure to use ripe mangoes, and if using canned mango, drain it thoroughly. Also, ensure your crumb mixture resembles damp sand, not wet dough.
Can I make these bars gluten-free?
Yes! You can easily make Mango Crumb Bars gluten-free by using a 1:1 gluten-free flour blend instead of all-purpose flour. This swap will help maintain the texture while accommodating gluten sensitivities.
What should I do if I have allergies to certain ingredients?
If you have dietary restrictions, consider alternative ingredients: use coconut oil instead of butter for a dairy-free version, or replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water) for a vegan option. Always consult with your doctor for specific allergies.
