How to make 5 Ingredient Lemon Bars
Ingredients:
- 1 cup salted butter, sliced
- 2 cups all-purpose flour
- 1/2 cup granulated sugar
- 1 1/2 cups granulated sugar
- 1/4 cup all-purpose flour
- 4 large eggs
- 1 cup lemon juice
Directions:
- Preheat and Prepare: Preheat your oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper, letting the edges hang over the sides for easy removal later.
- Make the Crust: In a mixing bowl, combine 1 cup of sliced butter, 2 cups flour, and 1/2 cup sugar. Use a pastry cutter or food processor to mix until the texture resembles coarse crumbs. Press this mixture evenly into the bottom of your prepared pan.
- Bake the Crust: Bake for about 15 minutes or until the edges turn lightly golden.
- Prepare the Lemon Layer: While the crust bakes, whisk together 1 1/2 cups sugar and 1/4 cup flour in another bowl. Add 4 eggs and 1 cup lemon juice, whisking until smooth and completely combined.
- Combine and Bake: Pour the lemon mixture over the hot crust, spreading it evenly. Return to the oven and bake for 40–50 minutes, or until the center is set and no longer jiggles.
- Cool and Serve: Let the bars cool completely at room temperature. Dust with powdered sugar before serving for a classic finish.
How to serve 5 Ingredient Lemon Bars
- Slice into neat squares using a sharp knife wiped clean between cuts for crisp edges.
- Serve chilled or at room temperature. A light dusting of powdered sugar or a few lemon zest curls adds an elegant note.
- Pair with a cup of Earl Grey, a tall glass of iced tea, or a dollop of whipped cream for extra decadence.
How to store 5 Ingredient Lemon Bars
- At room temperature: Keep in an airtight container for up to 2 days.
- In the refrigerator: Store covered for up to 5 days — chilling helps the lemon custard firm up and makes slicing tidier.
- For longer storage: Freeze individual bars wrapped tightly in plastic and foil for up to 2 months. Thaw in the refrigerator before serving.
Tips to make 5 Ingredient Lemon Bars
- Use fresh lemon juice when possible for the brightest flavor; bottled juice works in a pinch but tastes flatter.
- Let the lemon layer settle for a minute after pouring over the hot crust so bubbles rise and pop — this keeps the surface smooth.
- If the center browns before setting, tent lightly with foil and continue baking until set.
- For cleaner slices, chill the pan for an hour before slicing and warm the knife under hot water between cuts.
Variations (if any)
- Lemony Blueberry: Scatter a handful of fresh or frozen blueberries over the lemon layer before baking for jewel-like pops of sweetness.
- Almond Shortbread: Swap 1/4 cup of the crust flour for finely ground almonds for a nutty depth.
- Lighter Tart: Replace 1/2 cup sugar in the filling with a natural sweetener like honey, adjusting to taste.
FAQs
Q: My lemon filling wobbles in the center after baking — is it ruined?
A: Not necessarily. A slight wobble is normal and it will continue to set as it cools. If it’s very liquidy, return the pan to the oven for 5–10 minutes and recheck.
Q: Can I use unsalted butter instead of salted?
A: Yes. If using unsalted butter, add a pinch of salt to the crust to balance the sweetness and brighten the flavors.
Q: How tart will these be with 1 cup lemon juice?
A: They’re bright and pleasantly tart but balanced by the 1 1/2 cups sugar in the filling. Adjust by adding a tablespoon or two less sugar if you prefer extra zip.
Q: Can I halve the recipe or use a different pan size?
A: You can halve it and bake in an 8×8-inch pan, adjusting bake time slightly — keep an eye on the set of the center.
Q: Do I need to sift powdered sugar on top?
A: Sifting is optional but creates that classic, delicate finish that looks irresistible.
