How to make Lemon Crumb Bars

Ingredients:

1 cup all-purpose flour
1/2 cup unsalted butter, softened
1/4 cup granulated sugar
1/2 teaspoon salt
1/2 cup granulated sugar
2 large eggs
1/4 cup fresh lemon juice
1 tablespoon lemon zest
1/2 teaspoon baking powder
Powdered sugar for dusting

Directions:

Preheat your oven to 350°F (175°C) and grease an 8×8 inch baking dish.
In a bowl, mix the flour, softened butter, 1/4 cup sugar, and salt until crumbly. Press half of this mixture into the bottom of the prepared dish.
In another bowl, whisk together the eggs, 1/2 cup sugar, lemon juice, lemon zest, and baking powder. Pour this mixture over the crust in the baking dish.
Sprinkle the remaining crumb mixture on top of the lemon filling.
Bake for 20-25 minutes until the top is golden and the filling is set.
Allow to cool completely before dusting with powdered sugar and slicing into bars.

How to serve Lemon Crumb Bars

You can cut them into squares or rectangles, depending on your preference. These bars pair well with a cup of tea or coffee, making them great for afternoon gatherings.

How to store Lemon Crumb Bars

To store Lemon Crumb Bars, place them in an airtight container. They can last in the refrigerator for up to a week. If you want to store them longer, you can freeze the bars.

When you’re ready to enjoy them again, thaw them in the refrigerator overnight.

Tips to make Lemon Crumb Bars

Make sure the butter is at room temperature for easy mixing.
Use fresh lemon juice and zest for the best flavor. Bottled lemon juice can taste different and less flavorful.
Don’t skip the cooling step before dusting with powdered sugar; this helps the bars set properly and makes them easier to cut.

Variation

You can add a layer of fresh fruit like blueberries or raspberries on top of the lemon filling before adding the crumb mixture for an extra fruity twist. Another option is to add a teaspoon of vanilla extract to the egg mixture for a touch of added flavor.
