Lime Crumble Tart

Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

1½ cups all-purpose flour

½ cup granulated sugar

½ cup unsalted butter, cold and cubed

1 egg yolk

1 teaspoon vanilla extract

¼ teaspoon salt

½ cup fresh lime juice

1 tablespoon lime zest

1 can (14 oz) sweetened condensed milk

1 cup rolled oats

¼ cup light brown sugar

¼ cup unsalted butter, melted

Directions

I preheat the oven to 350°F (175°C).

In a large bowl, I combine 1¼ cups of the flour, granulated sugar, salt, and cold cubed butter. I mix until the texture looks like coarse crumbs.

I add the egg yolk and vanilla extract, then mix until just combined.

I press the mixture evenly into the bottom of a 9-inch tart pan.

I bake the crust for 15 minutes, or until it is lightly golden.

In another bowl, I whisk together the lime juice, lime zest, and sweetened condensed milk until smooth.

I pour the lime filling over the pre-baked crust.

In a separate bowl, I combine the rolled oats, remaining ¼ cup flour, brown sugar, and melted butter. I mix until crumbly.

I sprinkle the crumble topping evenly over the lime filling.

I return the tart to the oven and bake for 20 to 25 minutes, or until the top is golden brown.

I let the tart cool to room temperature before serving.

Variations

I like using lemon juice instead of lime juice when I want a softer citrus flavor.

I sometimes add shredded coconut to the crumble topping for a tropical twist.

I can also add a small pinch of cinnamon to the oat crumble when I want a warmer flavor.

For a sweeter finish, I like serving each slice with whipped cream or a dusting of powdered sugar.

Storage/Reheating

I store leftover Lime Crumble Tart in an airtight container in the refrigerator for up to 4 days.

I like serving it chilled or at room temperature. When I want the crumble slightly warm, I reheat a slice in a low oven for a few minutes until just warmed through.

I do not usually microwave it for too long because the filling can soften too much and the crumble may lose its texture.

FAQs

Can I make this tart ahead of time?

Yes, I can make this tart ahead of time. I like baking it the day before and chilling it in the refrigerator until I am ready to serve.

Can I use bottled lime juice?

I prefer fresh lime juice because it gives the tart a brighter flavor. Bottled lime juice works in a pinch, but the taste may be less fresh.

Do I need a tart pan?

I like using a 9-inch tart pan, but I can also use a similar-sized pie dish. The shape may look different, but the tart will still taste delicious.

Can I freeze Lime Crumble Tart?

Yes, I can freeze it after it cools completely. I wrap it well and freeze it for up to 2 months, then thaw it in the refrigerator before serving.

How do I know when the tart is done?

I know the tart is done when the crumble topping is golden brown and the filling looks set. I let it cool before slicing so the filling can firm up.

Conclusion

This Lime Crumble Tart is creamy, buttery, tangy, and sweet with a golden oat topping that makes every bite comforting. I love making it when I want an easy homemade dessert that feels fresh, bright, and special.
