Dessert in Under an Hour

I came up with this version the afternoon unexpected guests texted that they were ten minutes away, and somehow it saved the day.

Learn more about DanyRecipes and why I always keep a speedy recipe up my sleeve. These easy lemon bars go from pantry to plate faster than you would believe.

Why These Bars Feel Like Magic

This easy lemon bars recipe skips the long chill by using a thinner layer in a quick-setting pan, and a blender does the work of whisking in seconds. A cold bar is still best, but a quick freezer rest gets you clean slices in just 20 minutes.

These lemon bars recipe easy staples fit a standard 8×8 pan, and the whole thing takes about 15 minutes of work. They are one of my favorite lemon desserts for last minute plans, and they sit nicely beside my chewy thumbprint lemon curd cookies on a dessert plate.

Fast Pantry Ingredients

For the crust:

  • 1 1/4 cups all purpose flour
  • 1/4 cup powdered sugar, plus extra for dusting
  • 1/8 teaspoon fine salt
  • 1/2 cup (1 stick) unsalted butter, melted

For the lemon filling:

  • 3/4 cup granulated sugar
  • 2 large eggs
  • 1/4 cup fresh lemon juice, strained
  • 2 teaspoons lemon zest, finely grated
  • 2 tablespoons all purpose flour
  • Pinch of salt

Fast Steps to Sweet Success

STEP 1

Heat the oven to 375°F and line an 8×8 pan with parchment, leaving an overhang on two sides.

STEP 2

Stir the flour, powdered sugar, salt, and melted butter until a soft dough forms, then press it into the pan.

STEP 3

Bake the crust for 12 minutes until lightly golden while you prepare the filling.

STEP 4

Blend the sugar, eggs, lemon juice, zest, flour, and salt for 10 seconds until smooth, or whisk by hand for one minute.

STEP 5

Pour the filling over the hot crust and bake for 15 to 18 minutes until the center barely wobbles.

STEP 6

Cool on a rack for 15 minutes, freeze for 20 minutes, then dust with powdered sugar and slice into squares.

Serving Ideas and Easy Twists

  • Serve straight from the fridge with fresh berries on top.
  • Add a spoonful of whipped cream for a creamy finish.
  • Pair with my crispy shortbread lemon curd cookies for a buttery crunch beside the soft bars.
  • Cut into small squares and set them on a platter with mint leaves.
  • Stir a pinch of poppy seeds into the crust for a pretty speckled look.

Ingredients
  

Shortbread Crust
  • 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
Lemon Filling
  • 3/4 cup granulated sugar
  • 2 large eggs
  • 1/4 cup fresh lemon juice strained
  • 2 teaspoons lemon zest finely grated
  • 2 tablespoons all-purpose flour
  • 1 pinch salt

Equipment

  • 8×8-inch baking pan
  • Parchment paper
  • Mixing bowl
  • Blender
  • Whisk
  • Measuring Cups and Spoons
  • Fine Grater or Zester
  • Cooling Rack

Method
 

  1. Preheat the oven to 375°F (190°C). Line an 8×8-inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
  2. In a mixing bowl, combine the all-purpose flour, powdered sugar, and salt. Add the melted butter and stir until a soft dough forms. Press the dough evenly into the bottom of the prepared pan.
  3. Bake the crust for 12 minutes, until lightly golden. While the crust bakes, prepare the lemon filling.
  4. Add the granulated sugar, eggs, strained lemon juice, lemon zest, all-purpose flour, and salt to a blender. Blend for approximately 10 seconds until smooth. Alternatively, whisk by hand for about 1 minute, just until combined.
  5. Pour the lemon filling over the hot crust. Return the pan to the oven and bake for 15 to 18 minutes, until the edges are set and the center barely wobbles when gently nudged.
  6. Remove the pan from the oven and cool on a rack for 15 minutes. Transfer to the freezer for 20 minutes to help the filling set quickly. Dust with powdered sugar, lift out using the parchment overhang, and slice into squares. For an alternative, refrigerate for at least 2 hours instead of using the freezer.

Pro Tips

  • Pour the filling onto the hot crust so the layers bond and the bake time stays short.
  • Strain the lemon juice so no seeds slow you down or spoil the smooth filling.
  • Use the freezer rest only briefly, and never leave the pan in longer than 30 minutes.
  • Pull the pan when the center still wobbles, since it firms up as it cools.
  • Wipe your knife between cuts for clean, tidy squares.
  • Dust with powdered sugar right before serving so it stays bright white.

FAQs

Can I skip the freezer rest?
Yes, but the bars need at least 2 hours in the fridge to slice cleanly. The freezer simply speeds things up when you are short on time.

Can I use a blender for the filling?
Yes, a quick 10 second blend makes the filling smooth. Avoid blending longer, since extra air can create foam on top.

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 did my bars brown too fast?
Ovens vary, especially at 375°F. Move the pan to the center rack and tent loosely with foil if the top darkens early.

Fast, Sweet, and Magical

A speedy dessert that still tastes homemade is one of the best tricks in any kitchen. I hope these bars rescue your next last minute plan. For more citrus treats, try my melt in your mouth lemon curd cookies, the 5 ingredient glazed lemon curd cookies, or the zesty drop lemon curd cookies.
