How to Make a Graham Cracker Crust (+Gluten Free Option)

  • Pulse your graham crackers in a food processor into fine crumbs. Alternately, you can place your grahams in a zip lock baggie and smash with a rolling pin (which can be quite satisfying sometimes, especially on those heavy bickering days), then roll (on top of the baggie) until you get fine crumbs.

NOTE | Transform this torte easily into a gluten free dessert, simply replace regular graham crackers with GF grahams.

  • Add sugar and pulse to combine.

  • Slowly drizzle in melted butter while pulsing on low to combine. Pat crumbs evenly into a 9 or 10″ springform pan.
  • CHILL in the refrigerator for at least an hour before adding your batter.

Kathleen’s Pro TIP: Use a piece of wax paper or plastic wrap to press crumbs evenly and firmly.

Next you’ll make the “fluffy-limey part” of the torte.

How to make key lime tart filling

  • Separate the eggs, I still do it the old fashioned way, back and forth between the shells. Don’t throw those whites or yolks out though, you’ll need them both.
  • Add yolks to large mixing bowl, whisk until they lighten slightly in color. Pour in sweetened condensed milk and whisk until combined with egg yolks.

  • Next pour in lime and lemon juice…whisking well.
  • Then add lime zest, whisking it all together. Oh how I love lime zest, it’s so bright and pretty and packed with flavor.
  • If your crust is done chilling, now would be a great time to preheat your oven to 325°.

Kathleen’s Pro TIP | Zest your limes BEFORE you juice them!

  • In a separate, clean bowl; using a hand mixer, whip the egg whites until they are frothy. Then add your sugar and continue whipping until stiff peaks form.
  • You’ll know they are ready when you lift your mixers beaters; if ready there will literally be little peaks that stay standing and don’t floomp over. If they sag or droop too much, just whip a bit longer. They should get nice and glossy and grow in volume.

Fold the egg whites into the lime batter using a large spatula literally “fold” the mixtures together. Don’t stir! Gently, scoop to the bottom, pull the batter up and turn over onto the egg whites, continue doing so until the egg whites are incorporated into the batter.

Be patient, this part takes a bit of time, but resist from stirring to get it done, it doesn’t take longer than a couple of minutes and this will leave you with a lighter than air filling.

When it’s all incorporated, pour it onto the chilled graham cracker crust.

Bake at 325° for 15-20 minutes until edges start to brown ever so slightly and the middle looks a bit dry. It might even crack as it cools. That’s okay, you’ll cover up those cracks with whipped cream!

Cool completely on a cooling rack, refrigerate for 6-8 hours. I only chilled this one 4, I rushed it, it’s better if it goes a bit longer, this is a great make ahead dessert.

When ready to serve, using a butter knife, run it between the edge of the pan and the torte, then carefully “spring” your pan and gently lift off the collar from the pan. Slice into pie sized servings.

  1. Purchase real heavy whipping cream and pour into bowl and whip until thickened slightly.
  2. About half way through whipping, add powdered sugar and a touch of vanilla, continue whipping until you have stiff peaks and the whipping cream is firm. Be careful you don’t accidentally make make sweet butter! It’s easy to do.
  3. Spoon whipped cream into a baggie or a piping bag, if desired, snip off about ¾ – 1 ” of the baggie corner and “pipe” onto the torte slice. Garnish with a little more lime zest and a slice of lime if desired. Or, just scoop a dollop onto each piece.
