On the nights I want dessert but dread a sink full of dishes, this is the recipe I reach for.

Learn more about DanyRecipes and why I love cozy baking with minimal cleanup. These easy lemon bars come together in a single bowl and bake into a tangy, buttery treat.

Why One Bowl Makes Everything Easier

This easy lemon bars recipe uses melted butter, so there is no cutting in, no mixer, and no chilling the dough. The crust and the filling are both stirred by hand, and you can even use the same bowl for both if you give it a quick wipe in between.

These lemon bars recipe easy staples fit a standard 8×8 pan and need nothing fancy. They are one of my favorite lemon desserts for lazy afternoons, and they sit nicely beside my chewy thumbprint lemon curd cookies on a dessert plate.

Ingredients

1 1/4 cups all-purpose flour
1/4 cup powdered sugar plus extra for dusting
1/8 teaspoon fine salt
1/2 cup unsalted butter 1 stick, melted and slightly cooled
1/2 teaspoon vanilla extract

Lemon Filling

1 cup granulated sugar
2 large eggs at room temperature
1/3 cup fresh lemon juice strained
1 tablespoon lemon zest finely grated
2 tablespoons all-purpose flour
1 pinch salt

Equipment

8×8-inch baking pan
Parchment paper
Large Mixing Bowl
Whisk
Measuring Cups and Spoons
Spatula
Fine Grater or Zester
Cooling Rack

Method

Preheat the oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving an overhang on two sides to make removing the bars easier.
In a large mixing bowl, stir together the all-purpose flour, powdered sugar, and salt. Add the melted, slightly cooled butter and vanilla extract. Mix until a soft dough forms.
Transfer the dough to the prepared baking pan. Press it evenly across the bottom using your fingers or a spatula. Bake for 15 to 18 minutes, until lightly golden. Remove the pan from the oven and carefully wipe the mixing bowl clean.
In the same bowl, whisk together the granulated sugar, eggs, strained lemon juice, lemon zest, all-purpose flour, and salt until smooth and fully combined.
Pour the lemon filling evenly over the warm baked crust. Return the pan to the oven and bake for 18 to 22 minutes, until the edges are set and the center has only a slight wobble when gently nudged.
Remove the pan from the oven and cool completely on a cooling rack. Refrigerate for at least 2 hours until firm. Lift the bars out using the parchment overhang, dust with powdered sugar, and slice into squares.

Notes

Pro Tips:

Let the melted butter cool slightly before mixing to avoid cooking the eggs when preparing the filling.
Wipe the mixing bowl thoroughly between preparing the crust and filling to keep the lemon mixture smooth.
Press the crust firmly and evenly into the pan so it holds together when sliced.
Remove the bars when the center still has a slight wobble, as the filling will continue to set while cooling.
Chill completely before cutting for neat, clean squares.
Dust with powdered sugar just before serving to keep the topping fresh and bright.

Serving Suggestions: Serve chilled with fresh berries, whipped cream, or vanilla yogurt. Add a pinch of poppy seeds to the crust for extra texture. For a larger gathering, double the ingredients and bake in a 9×13-inch pan, adding approximately 3 to 5 minutes to the filling bake time while checking for a gentle wobble.

Storage: Cover and refrigerate for up to 4 days, placing parchment paper between layers. Freeze undusted bars for up to 2 months.

Troubleshooting: If the crust turns greasy, the butter may have been too warm or the dough insufficiently pressed. Allow the butter to cool slightly and press the crust firmly into the pan. If the bars are difficult to slice, chill them longer before cutting.

Freshly squeezed lemon juice is recommended for the brightest flavor. If necessary, use pure bottled lemon juice that is not from concentrate.

Pro Tips

Let the melted butter cool slightly so it does not cook the eggs in the filling.
Wipe the bowl well between the crust and the filling to keep the filling smooth.
Press the crust firmly so it holds together when sliced.
Pull the pan when the center still wobbles slightly, since it sets as it cools.
Chill fully before cutting for neat, tidy squares.
Dust with powdered sugar right before serving so it stays bright white.

FAQs

Can I really use just one bowl?
Yes, mix the crust first, press it into the pan, and wipe the bowl before whisking the filling. You can also use a second bowl if you prefer.

Can I double this recipe?
Yes, double everything for a 9×13 pan and add 3 to 5 minutes to the filling bake time. Watch for that gentle wobble in the center.

How should I store the bars?
Cover and refrigerate for up to 4 days, with parchment between layers. Freeze undusted bars for up to 2 months.

Can I use bottled lemon juice?
Fresh juice tastes brighter, so I recommend it. If you must use bottled, choose a pure, not from concentrate variety.

Why is my crust greasy?
The butter was likely too warm or the dough was not pressed firmly. Let the butter cool slightly and press the dough tightly into the pan.

Easy, Cozy, and Done

A great dessert does not have to mean a messy kitchen, and these bars prove it. I hope they make your next baking day a little lighter and a lot sweeter.
