This sunny, tangy lemon layered dessert brings summer vibes to your table any time of year. The mix of zesty lemon, smooth filling, and crispy cookie foundation makes an eye-catching no-bake treat that gets gobbled up quickly at any gathering.
I whipped up this lemon treat for our street party last summer when it was blazing hot. Everyone wanted to know how I made it, and now my friends expect me to show up with it at every warm-weather potluck.
What You'll Need
- Lemon sandwich cookies: these form your base and can top your dessert with real lemon taste
- Salted butter: holds the base together and balances the sweetness with a hint of richness
- Cream cheese: makes a silky middle section that works well with the zingy lemon
- Granulated white sugar: adds just enough sweetness to the cream cheese without going overboard
- Sour cream: brings a lovely zing and helps the cream cheese layer feel extra smooth
- Whipped topping: adds fluffiness throughout - try real whipped cream for something special
- Lemon pie filling: packs a punch of lemon flavor without extra work
- Heavy cream: gets the lemon layer just right for easy spreading
- Lemon juice: adds fresh zip - always squeeze it yourself for the best flavor
- Vanilla pudding mix: helps everything stay put and adds creaminess without stealing the lemon spotlight
- Lemon zest: sprinkle on top if you want - it looks pretty and boosts the lemon kick
Easy Assembly Steps
- Get Your Pan Ready:
- Put parchment paper in a 9x13 inch pan with extra hanging over the sides so you can lift it out later. If you don't have parchment, just give the pan a light spray so nothing sticks, especially in the corners.
- Make Your Cookie Bottom:
- Crush the lemon cookies in a food processor until you've got fine crumbs with no chunks left. It shouldn't take more than 30 seconds of pulsing. Pour melted butter in while the machine runs until everything looks like wet sand. No dry spots should remain. Press this mix firmly into your pan, using a measuring cup bottom to make it nice and flat.
- Whip Up The Cream Cheese Mix:
- In a big bowl, beat cream cheese until it's totally smooth. Getting all the lumps out is super important. Add sugar and keep beating until it's light and fluffy, about 2 minutes. Mix in room-temp sour cream until everything blends perfectly. The mix should look smooth with a slight shine. Carefully fold in 2 cups of whipped topping with a spatula, using gentle strokes to keep it airy. Spread this over your cookie base, making sure to reach all the edges.
- Fix The Lemon Layer:
- In another bowl, mix lemon pie filling, heavy cream, and fresh lemon juice until smooth. You'll need to put some muscle into it to get rid of all lumps. Add 2½ tablespoons of vanilla pudding mix and keep whisking until it gets a bit thicker. The pudding mix helps this layer stay put. Gently pour and spread this bright yellow mix over your cream cheese layer, trying not to mess up what's underneath.
- Add The Final Touch:
- Take what's left of your whipped topping and mix in the last tablespoon of vanilla pudding. This helps your top layer keep its shape when cut. Spread this on top of everything, making pretty swirls if you want. The white top looks great against the yellow lemon underneath.
- Let It Set:
- Cover everything with plastic wrap, making sure it doesn't touch the top. Chill for at least 4 hours, but leaving it overnight works even better. This sitting time lets all the flavors mingle and helps everything firm up so you can get clean slices.
- Dress It Up And Dig In:
- Right before you serve it, sprinkle lemon zest and some crushed lemon cookies on top for extra crunch and eye appeal. Cut into squares using a sharp knife, wiping it clean between cuts for the neatest edges.

This sweet treat always reminds me of hanging out at my grandma's screened porch in the summer, enjoying her lemon desserts. The bright yellow filling makes me think of sunshine even when it's pouring outside, and I find myself making it whenever I need a mood boost.
Delightful Do-Ahead Option
This lemon treat actually tastes better when you make it a day early, giving everything time to meld and set up nicely. You can even prep it two days ahead if needed. Just keep it covered in your fridge and add the toppings right before you serve it so they look fresh. The cookie bottom will soften a bit over time, which many folks actually prefer since it makes cutting and serving much easier.
Clever Swaps
Can't find lemon sandwich cookies? Graham crackers work great for the base - just add 2 tablespoons of sugar and 1 teaspoon of lemon zest to keep that lemony kick. Want something lighter? Try low-fat cream cheese and light sour cream, though it won't be quite as rich. In a pinch, you can mix lemon curd with whipped cream instead of using store-bought lemon pie filling. Just remember that homemade switches might need extra time in the fridge to firm up properly.

Ways To Serve
This bright dessert goes wonderfully with fresh berries, especially blueberries or raspberries that really complement the lemon flavor. For fancy occasions, put each slice over a little pool of raspberry sauce with a small scoop of vanilla ice cream on the side. At summer get-togethers, I like to make this the star of a dessert table with fresh fruit and mint sprigs around it. Want to show off those pretty layers? Serve in clear glass dishes so everyone can see them.
