Lemon icebox bars

Summer is not over yet. And that means, bring on all the lemon desserts!

No-bake desserts can either be surprisingly delicious or expectantly disappointing. Am I right? I feel like there are so many times where I’ve experienced both. To put this to the test, last year I tried a no-bake lemon pie. It turned out to be the former – surprisingly delicious. I liked the idea of not using the oven and trying something new.

This year, I decided to develop my own recipe. I knew I wanted to try three things specifically – make homemade lemon curd, crust, and incorporate mascarpone.

Homemade lemon curd is not as intimidating as it sounds! With just four ingredients, you can whip up a fresh (preservative-free) curd in less than 10 minutes! More on this below.

The last recipe I followed called for Golden Oreos to make the crust – which truthfully, was very delicious. However, there’s already so much sugar involved in the recipe, and I wanted to find a cookie minus the filling. The answer: shortbread cookies.

After recently making tiramisu for the first time (another no-bake recipe), I was inspired to use mascarpone. It’s basically cream cheese’s sexy Italian cousin with all the soft moves.

The layers of these lemon bars from bottom to top:

The crust.

It consists of crumbled up shortbread cookies and which are bound together by melted butter. Simply put the cookies in a food processor, mix in some melted butter and combine until you get a course-like sand texture.

The pudding.

Kicking it old school with instant pudding. I prefer the cheesecake flavor, but you could also use vanilla. Add milk to the pudding and let it set for a few minutes. Then mix in some of the Cool Whip for a silky-smooth texture.

The lemon curd.

You can use store-bought (I’ve seen some at Trader Joe’s), but I prefer to make my own. Tastes 100% better. Here’s how:

  1. In a small saucepan, combine 3 whole eggs, ½ cup sugar, ¼ teaspoon salt, ½ cup fresh lemon juice and zest of 1 lemon. Whisk until there’s a smooth consistency.
  2. Turn on the heat. Set to low. Whisk constantly until the mixture thickens 5-10 minutes. Make sure to do this on low heat and whisk slowly so eggs don’t scramble.
  3. Add 4 tablespoons cubed butter. Stir until the curd forms and coats the back of a spoon.
  4. Remove from heat and pour into a jar or small bowl. If needed, strain out any egg white pieces. Allow to cool completely. (Can put in fridge to expedite the process, but don’t let it harden!)

After lemon curd cools, add mascarpone and mix until smooth and the spoon creates silky ribbons.

The Cool Whip.

The final layer is straight up Cool Whip from the carton. You’re welcome to use whipped cream (even homemade), but it won’t last as long if you’re storing leftovers. Feel free to garnish with more lemon zest for an extra zing!

Note: *After each layer is added, allow 10-15 minutes to set in the freezer and then an additional 2 hours in the fridge once complete.

You Might Be Wondering:

What does “icebox” mean?

  • According to history, icebox referred to the non-mechanical form of refrigeration that was used commonly before the 1950s. Icebox cakes and pies are popular no-bake recipes and frequently fruit forward.

How do you get such clean and precise cuts of the lemon bars?

  • Run a knife under super cold water for 15-20 seconds. Divide the bars into even rows cleaning the knife with a paper towel in between cuts.

What occasions is this good for?

  • Memorial Day and Labor Day BBQ’s and parties! TBH though, any excuse you have to gather with friends and family, especially during the hot summer days, yields this as the perfect dessert.

Equipment Needed

  1. 8 X 8 baking dish
  2. Parchment paper
  3. Food processor or blender
  4. Medium and small bowl
  5. Small sauce pan* (If making homemade lemon curd)

Ingredients

  • One box shortbread cookies
  • 3 tablespoons butter, melted and cooled
  • 1 box instant pudding – Cheesecake flavor
  • 1.5 cups milk*, cold
  • 8-12 oz Cool Whip, room temperature
  • 1 1/3 cup lemon curd*
  • 6 oz mascarpone, room temperature
  • Optional: lemon zest for garnish

Notes: 

*Milk – whole or reduced-fat work, but no milk alternatives like almond or oat milk.

*Lemon curd – can be store-bought or homemade. Look at blog post above for cooking instructions.

Instructions

  1. Line a 8X8 pan with parchment paper.
  2. Using a food processor or blender, pulse cookies until they form course-like crumbs. Mix with 3 tbsp melted butter until bound together. Form and press the crust into an even layer inside the pan. Set in the freezer for 15 minutes.
  3. In a medium bowl, whisk the contents of the pudding with 1.5 cups of cold milk for 2 minutes. Let it sit for 5 minutes undisturbed.
  4. Gently fold 1.5 cups of Cool Whip into pudding. Spread half of mixture into an even layer on top of the shortbread cookie crust. Set in the freezer for 5-10 minutes. Reserve other half of pudding for another dessert!
  5. In a small bowl, mix 1 1/3 cup lemon curd with 6 oz mascarpone until silky smooth. Gently spread on top of the pudding layer (without disturbing the layers below). Set in freezer for 5-10 minutes.
  6. Spread 1-2 cups Cool Whip on top of the lemon curd layer. This is the final layer. Set in fridge and cover for at least 2 hours. 
  7. Run a knife under very cold water and dry it. Use to cut clean slices of the bars to serve and enjoy! Garnish with lemon zest if you desire an extra zing.

Recipe Notes:

  • Store bars in an airtight container or tightly cover pan with Saran Wrap in fridge for up to 5 days. Or, my preference is to keep in the freezer for up to 2 weeks. Allow to “defrost” for a few minutes before serving.

I'm admittedly not a baker (or a no-baker), but these were easy enough to make — yes, even the lemon curd — and they were a hit with my coworkers. I even won some brownie points with our CEO (or lemon bar points? whatever). Word to the wise: Keep them in the freezer them for longer than you think you should.

What a refreshing treat on a hot day! Each layer uniquely complimented the next. Take these zingy, light bars to your next gathering and you'll instantly make friends.

Are these bars heaven in four layers? I think so. The flavors are perfectly balanced: cool, sweet, salty, and crumbly. Do yourself a favor and whip these up before summer is over.

These were such a pleasant treat! We had them as a follow up to a dinner of baked feta with chili and honey and roasted whitefish with Mediterranean topping of olives and tomatoes. Highly recommend these as a sweet finish to the waning days of summer.
