No Bake Kit Kat Squares

No Bake Kit Kat Squares are an easy recipe for a layered chocolate dessert that come together without baking. Kit Kats are a favorite or mine but you could easily try this with other candy bars too. The video shares a version made with an assortment of Halloween candy.

No bake Kit Kat Squares are the solution to summer baking. Summer heat is upon us and nothing makes a warm home hotter than turning on the oven. Since I can’t imagine a week in the kitchen without eating goodies, I was happy to learn that the theme for #CreativeCookieExchange in July was No-Bake Cookies. Hooray! This kit kat bars recipe was perfect!

Candy Inspiration– endless possibilities!

I found inspiration in these no-bake nutter butter butterfinger bars from The Domestic Rebel. I loved the idea of taking a candy bar and turning it into another type of treat all together. Kit kat bars are a favorite of mine– milk chocolate with layers of wafers– and that is the thought behind this kit kat bars recipe.

Let’s walk through the steps to make Kit Kat Bars.

These photos were updated in 2018 and I made a version with leftover Halloween candy. It’s fun to turn trick or treat goodies into a new dessert!

Start by preparing your 8 by 8 pan and covering it with foil. Brush it with melted butter.

Measure 8 ounces of cookies for your crust. If you’d like this to be a gluten free recipe, select a gluten free cookie.

Pulse the cookies in a food processor. Add the melted butter and pulse until combined. Press this mixture in the bottom of your pan.

Move on to the chocolate. Combine the chocolate chips and sweetened condensed milk. Melt in the microwave then stir until smooth. Poor the chocolate mixture on top of the cookie crumb layer. Spread evenly.

Move on to the candy. Use all Kit Kats or use a mixture of Halloween candy. Six ounces is about right. Pulse in the food processor.

Spread the candy crumbs on top of the chocolate layer. Cover and place the bars int he refrigerator for 1-2 hours at least. Overnight is great too.

Enjoy this no bake dessert made with Kit Kat. Switch up the candy to your favorite! If you wish to make this gluten free, use gluten free cookies for the base and gluten free candy for your topping!

Prep Time 15 minutes
Additional Time 4 hours
Total Time 4 hours 15 minutes


  • 8 tablespoons butter, melted
  • 8 ounces cookies (vanilla wafers or other plain wafer cookie)
  • 1 can sweetened condensed milk (14 oz)
  • 12 oz chocolate chips
  • 3 packages of 1.5 oz kit kat bars (4 kit kat fingers per package)


  1. Line an 8 x 8 glass baking dish with foil so that the edges are overhanging. This extra foil will act as handles when the dessert is taken out of the pan. Brush with 1 tablespoon of butter.
  2. Pulse the cookies in the food processor until crumbs are formed then add the remaining 7 tablespoons melted butter and process until combined. Press the wafer crust firmly into the bottom of the pan.
  3. Pour the sweetened condensed milk and the chocolate chips into a glass bowl. Microwave for one minute, stir, then microwave for 30 seconds more. Stir again. The mixture should be smooth but if not, microwave in additional 15 second increments then stir each time. *Note: milk chocolate chips can be used for the most authentic kit kat chocolate flavor but I chose to use dark chocolate chips to add a different chocolate layer than the topping. You pick your favorite. You can't go wrong.
  4. Pour this chocolate layer on top of the wafer crust.
  5. Next, pulse the kit kat bars in the food processor until the size of crumbs. Scatter on top of the chocolate layer then press lightly with a spatula.
  6. Cover with plastic wrap and refrigerate at least an hour or even overnight.
  7. Cut into 16 squares to serve.


Try this recipe with other candy such as heath bars or chocolate covered toffee.

Thanks fort our reply Holly. One more question. If using shortbread do I keep same amount of butter ?

Holly Baker

Thursday 17th of December 2020

I think I would because the butter is there to help hold the base layer together. Yes, this will be extremely decadent and loaded with butter and goodness...but as we are not aiming for a low-cal dessert in the first place, I'd say stick with the same amount of butter. Let me know how it goes!

CAN you use shortbread cookies. Cannot find Vanilla wafers similar to yours anywhere. Thank you

Holly Baker

Yes, of course! Shortbread will be a bit thicker but fine. Graham crackers might work too.

Are the chocolate chips milk chocolate or semisweet?

Use whatever kind you enjoy!

These sound amazing Holly! I can hardly wait to try them. I'm thinking of trying them with a Rice Krispie base as well! Thank You for the recipe!

Rice krispies would be really good on the bottom-- I'll have to try it! Glad you like these kit kat bars.

When I cut my squares after being refrigerated for more than 6 hours the base crumbled and fell apart. There didn’t seem to be enough melted butter to hold the crumbs together. Not sure what went wrong. The filling is quite rich but I love the Kit Kat flavour.

Oh no, Gloria, that doesn't sound right. I am really sorry to hear that the bars didn't stay together. Perhaps you could press the crust down more firmly next time? Or adding more butter might help too.
