These Lemon Crumb Bars are sunshine in dessert form buttery, sweet, tangy, and beautifully soft with a golden crumb topping. They’re wonderfully simple to make, yet taste like something from a charming little bakery. Perfect for spring gatherings, afternoon treats, or whenever you’re craving bright lemon flavor.
Ingredients
For the crust & crumb topping:
- 1 cup unsalted butter, melted
- 1 cup granulated sugar
- 2 cups all-purpose flour
- 1/2 tsp salt
- 1 tsp vanilla extract
For the lemon filling:
- 1 can (14 oz) sweetened condensed milk
- 1/2 cup fresh lemon juice
- 1 tbsp lemon zest
- 2 large egg yolks
Optional: Add an extra tablespoon of zest for a bolder lemon flavor.
Steps
- Make the crumb base. Mix melted butter, sugar, flour, salt, and vanilla until sandy and soft. Don’t worry it’s supposed to resemble crumbs.
- Press into a pan. Add 2/3 of the mixture to a parchment-lined 8×8 pan and press firmly.
- Bake the crust at 350°F for 10 minutes to give it a head start.
- Mix the filling. Whisk condensed milk, lemon juice, zest, and egg yolks until smooth and creamy.
- Pour over the warm crust. Spread evenly, then sprinkle the remaining crumb mixture on top.
- Bake for 20–25 minutes, until the edges are lightly golden and the center looks set.
- Cool completely. Chill for at least 1 hour for clean, beautiful slices.
Chef’s Tips
- Use fresh lemon juice: It makes the filling brighter and more vibrant.
- Press the crust firmly: A tight base helps the bars hold together.
- Chill before slicing: It keeps the layers neat and the texture perfect.
Variations
- Lemon blueberry bars: Add 1/2 cup fresh blueberries to the filling.
- Coconut lemon bars: Mix 1/4 cup shredded coconut into the crumb topping.
- Lime twist: Swap lemons for limes for a refreshing citrus change.
