No-Bake Lemon Icebox Pie

---

No-Bake Lemon Icebox Pie is for lemon lovers and summer days. A puckery citrus mousse is chilled in a wafer crust and topped with mounds of sweet whipped cream.

Growing up Mom made this awesome summer dessert called Lemon Fluff. According to the wise world of Google its origins may have come from a 1951 issue of Better Homes and Gardens!

You can still find recipes similar to Mom's all over! They are ever so slightly different with the amounts, but the classic layers a fluffy mousse between vanilla wafer crumbs. That's it! But it was genius.

Lemon Fluff

I loved Lemon Fluff as a kid. I'm pretty sure my little brother had named it as his favorite dessert, so for years it was "Taylor's favorite dessert," instead of Lemon Fluff.

The name alone says 50's dessert. The main ingredients and method say 50's as well. By then Jello had been around for quite some time. Convenience foods had a grand introduction in the decades before. By the 50s it was felt that using convenience food was cheating, and housewives were better than that!

I made a no-bake lemon icebox pie by creating a fluffy, tangy filling in a cookie crust. This will be your go-to summer mousse pie.

Housewives would use convenience foods within a more complicated recipe to feel like they were cooking from scratch. There was no just making jello and serving it. You had to add to it and create a process using the convenience food!

The women's magazines jumped on board and Lemon Fluff heralded from that exact philosophy. Take convenience foods like lemon jello, canned milk, and boxed cookies and make a more elaborate treat!

As summer approaches I knew I needed to up my game on the no-bake treat category. My Easy Cheesecake In A Jar ranks as one of my favorite no-bakes. As does Coconut Key Lime Bars and No Bake Cheesecake Tart (but both of those cheat a bit and the crust gets baked for about 10 minutes!).

Updating a classic dessert:

I took to re-creating the old 50s dessert into a mousse pie. No prepared jello for me, I wanted a brighter flavor rather than just citric acid and lemon flavoring. I swapped the jello for lemonade concentrate and plain gelatin. I swapped the canned milk for fresh heavy cream and added butter to the wafer crumbs so I could get a slightly sturdy pie crust without baking.

Oh you better believe I kept those Vanilla Wafers as the crust. That classic flavor couldn't be swapped out! You can garnish the top with lemon zest curls or extra crumbled cookies. The crumbled cookies are more reminiscent of the classic dessert, but the lemon curls are just so pretty!

What is mousse pie?

A mousse pie filling has the texture of a lemon chiffon pie. Light, airy and still tangy and tart. A classic chiffon has egg whites folded into a curd or thickened filling to make it fluffy. A mousse is similar in texture and often made with chocolate. But mousse pie is what most of us think about when we make icebox pies in the summer. Whipped cream is folded into the thickened base instead of egg whites and the mixture thickens in the fridge.

I made this mousse pie with a lemonade gelatin as the thick base, and folded pillows of whipped cream in to make it have a chiffon texture. It's seriously dreamy in your mouth.

Give yourself some time to make and chill the homemade jello. The secret to perfection is making sure the plain gelatin is completely dissolved in the lemonade before chilling in the fridge. This ensures the gelatin activates all of the lemonade evenly and you get a sturdy base for the mousse.

 Mousse Pie Tips

I took to re-creating the old 50s dessert into a mousse pie. This no-bake lemon icebox pie is what memories are made of!

You want to set the lemonade gelatin only partially, so keep checking. It should just be starting to jiggle and solidify. Blend it until it's fluffed quite a bit (incorporating air is key for this dessert), and then fold in your whipped cream.

I've never promised this dessert is a one-bowl creation! You'll use quite a few of your mixing bowls! But really, how hard is it to wash a few bowls? Not hard at all. There is lemonade gelatin to make, cream to whip and butter to melt! You won't regret it.

Your cookie crust will have been chilling in the fridge or freezer while your jello sets, so it's ready for the filling. That crust isn't baked, so it's pretty fragile. It's not your typical sturdy, cookie pie crust. But that's one of my favorite parts of this no-bake lemon icebox pie, it is completely reminiscent of it's origin dessert, Lemon Fluff. Crumbly cookie crumbs holding up a light, airy, tangy filling. Enjoy!
