Begin With a Crumb Crust

Beneath you’ll discover my fundamental graham cracker crust recipe. It suits right into a 9-inch sq. baking pan completely, in addition to many 8-inch and 10-inch pans, and pie dishes. I really like this specific crust as a result of it’s altogether crunchy, buttery, thick, and never overly candy like many crumb crusts of its type.

Key limes may be tough to trace down out of season, which is almost all of the yr. They’re smaller, extra yellow, and slightly sweeter than normal limes. You’ll be able to substitute common limes for key limes on this recipe, or use half lime juice and half lemon juice.

Sure, completely. The model I sometimes purchase is known as Nellie & Joe’s Key West Lime Juice, and it’s bought in most main grocery shops subsequent to the bottled lemon juice. Not solely does this make it attainable for year-round key lime pie squares, however it’s additionally lots simpler than juicing all these tiny key limes by hand!

You additionally want the next components:

  1. Cream Cheese: I don’t use it in my key lime pie recipe, however I needed as we speak’s filling to lean slightly extra in direction of key lime cheesecake. The flavour is delicate—we’re solely utilizing 4 ounces of cream cheese within the filling (1/2 of a block), and that small quantity manages to supply the creamiest key lime pie bars on the earth. Keep away from the fat-free type.
  2. Egg Yolks: Egg yolks stabilize and arrange the important thing lime filling.
  3. Sweetened Condensed Milk: One 14-ounce can of full-fat sweetened condensed milk sweetens the dessert and offers a easy texture. I additionally use this in my oatmeal lemon crumble bars.
  4. Lime Zest: Lime zest provides the filling some colourful speckles, to not point out much more lime taste. Zest both 1 common lime or 2 key limes.

Unfold the filling over the crust whereas the crust continues to be heat. Why? This can assist the filling adhere to the crust slightly higher.

Learn how to Lower Neat Squares

Cool baked key lime pie bars at room temperature for about 1 hour, after which refrigerate them for two hours or till the underside of the pan feels chilly. If you happen to minimize the bars into squares too early, they’ll disintegrate. If I’m serving these at a celebration or occasion, I put together them the night time earlier than simply so I do know they’ll cool and chill lengthy sufficient to yield neat squares.

Slice them with a pointy knife and wipe the knife clear between every minimize.

You want simply 7 components to make these easy key lime pie bars, a handheld model of my key lime pie recipe. Immediately’s bars are creamy and tangy with a easy graham cracker crust. Be sure you cool and chill the bars earlier than chopping into squares.


  1. Preheat oven to 350°F (177°C). Line a 9-inch sq. baking pan (I really like this one and this one) with parchment paper, leaving an overhang on the edges to simply raise the bars out of the pan. Put aside.
  2. Make the crust: If you happen to’re beginning out with full graham crackers, use a food processor or blender to grind them into nice crumbs. It’s also possible to place them in a zip-top bag and crush them into nice crumbs with slightly arm muscle and a rolling pin. Stir the graham cracker crumbs and granulated sugar collectively in a medium bowl, after which stir within the melted butter. The combination shall be thick, coarse, and sandy. Attempt to smash/break up any giant chunks. Press into the underside of the lined pan.
  3. Prebake crust: Bake the crust for 10 minutes. Cool for a couple of minutes as you put together the filling within the subsequent step.
  4. Make the filling: Utilizing a handheld or stand mixer fitted with a paddle or whisk attachment, beat the cream cheese on medium-high pace till easy, about 1 minute. Beat within the egg yolks. Scrape down the edges of the bowl as wanted. Beat within the sweetened condensed milk, key lime juice, and lime zest till mixed. After mixing the filling along with your mixer, give it a closing whisk by hand to ensure there are not any cream cheese lumps on the backside of the bowl. Pour/spoon filling evenly onto the nice and cozy crust.
  5. Bake for about 18-20 minutes, or till the perimeters of the bars seem set and the middle is simply *barely* jiggly.
  6. Take away from the oven and permit to chill for half-hour at room temperature on a wire rack after which chill within the fridge for a minimum of 2-3 hours.

Use 200g floor digestive biscuit crumbs as an alternative (about 13–14 biscuits), the identical quantity of butter, and add a bit extra sugar (about 1/3 cup, or 67g). You might want so as to add just a few further minutes to the pre-baking time, as digestive biscuits should not fairly as crispy-crunchy as graham crackers. And from what I perceive, spreadable cream cheese bought in a bath in nations exterior of the US is slightly totally different from the spreadable cream cheese within the US. It’s thicker, sturdier, and extra strong and ought to be OK to make cheesecake. I’ve no expertise with it, however that is what I’ve heard from different non-US readers.
