Lime Bars Graham Crust

My grandmother kept lime trees in her backyard, and I spent countless summer afternoons squeezing fruit into mismatched bowls while she explained that patience was the secret to every dessert worth making.

I brought these to a potluck last summer and watched my usually stoic brother close his eyes while eating one, then immediately ask for the recipe before anyone else had even served themselves.

Ingredients

• Graham cracker crumbs: Fresh crumbs make a noticeable difference, but pulse whole crackers in a food processor if needed
• Unsalted butter: Melt it completely and let it cool slightly so it mixes evenly without clumping
• Granulated sugar: This amount balances the tartness perfectly without making the filling cloyingly sweet
• Large eggs: Room temperature eggs incorporate more smoothly into the filling mixture
• Lime juice: Fresh is absolutely essential here, nothing else gives that bright, floral citrus punch
• Lime zest: Zest your limes before juicing them to make life infinitely easier
• Whole milk: Adds just enough richness to temper the sharp acidity of the lime

Instructions

Prepare your pan:

Parchment paper with overhangs will save you so much frustration when it comes time to lift these out

Make the crust:

Mix everything until it resembles wet sand, then press it firmly into an even layer using the bottom of a measuring cup

Pre-bake the crust:

This step prevents soggy bottoms and gives the crust a head start on becoming crisp and golden

Whisk the filling:

Combine everything until no streaks remain, but do not overwhisk or you will incorporate too much air

Bake until set:

The center should still have a slight wobble, like gelatin, when you gently shake the pan

Let them cool completely:

This is the hardest part but absolutely necessary for clean slices that hold their shape

Something magical happens when the filling firms up in the refrigerator, transforming from jiggly uncertainty into something that holds its shape with quiet confidence.

Getting Clean Slices

Run a sharp knife under hot water and wipe it clean between cuts for those picture-perfect squares that make people think you have professional training.

Make Ahead Magic

These bars actually improve after a day in the refrigerator, as the flavors meld together and the crust becomes even more substantial and satisfying.

Serving Suggestions

A light dusting of powdered sugar right before serving makes these look like they came from a bakery window.

• Add a dollop of softly whipped cream if you want extra richness
• Fresh berries on the side add beautiful color and contrast
• These pair surprisingly well with a cup of Earl Grey tea

Save to Pinterest

There is something deeply satisfying about serving something so bright and cheerful on a plate, watching people's faces light up with that first unexpected bite of sunshine.
