I’ll be honest. I used to do a lot more from-scratch baking, especially for special occasions. But now I’m more than happy to outsource cakes (@mothermillscakes in Utah is my latest fave) and cheesecakes (trying @pies_the_limiut this week). But when someone asks for my famous easy key lime pie, I’ve gotta make that myself!

Granted, I’m happy to make chocolate brownie trifle or peach cobbler dump cake (SO good with ice cream) if they ask, but key lime pie with homemade whipped cream is probably my favorite because it receives such rave reviews.

You can totally make this recipe even easier if you buy a graham cracker crust from the store, but there’s something about smashing up those graham crackers that’s good for the soul (especially if it’s been a frustrating day).

If you prefer a little less work and finer crumbs, use a food processor or blender to grind the graham crackers. I like my crust a little more coarse, so I use my wooden rolling pin. While my old middle school woodshop class rolling pin works well, I’m dying to try this French rolling pin!

Plus, homemade graham cracker crust tastes way better than storebought any day.

And guess what? If you can’t find key lime juice, you can use regular lime juice. Last time I made this recipe, I doubled it so Nathan could have his very own birthday pie but discovered partway through, I didn’t have enough key lime juice.

I substituted regular ol’ lime juice and the pies still tasted fantastic. Whew!

Of course, nothing beats the homemade whipped cream on top, not even the extra creamy canned stuff. Don’t get me wrong, the canned stuff is good to have on hand when you need a quick shot of somethign sweet.

But making it yourself means you can make it as sweet as you’d like! With key lime pie, I do a little extra sugar since the pie is on the tart side. But if I’m using it to top something like brookies or applesauce crunch cake, I’ll cut back a bit on the sugar.
