Kit Kat

My cookie bars are topped with my favorite candy bar, the Kit Kat Bar! Buttery cookie bars around the edges while chewy sweet in the center.

Be sure to try my Malted Chocolate Chip Cookie Bars recipe too! Follow Picky Palate on Instagram for daily recipe inspiration.

What You’ll Need

butter– For most of my recipes I use salted butter. Unsalted works too.
brown sugar, dark– Dark brown sugar is deeper in color and has more molasses in it. It is located by the light brown sugar.
granulated sugar– This fine white sugar adds sweetness to the bars.
2 large eggs– For consistency, I use large eggs in my cooking and baking.
pure vanilla extract– For best tasting results use pure vanilla.
all-purpose flour– Flour is the main dry ingredient in the bars.
vanilla instant pudding mix– Find the pudding mixes near the cake mixes in the baking isle of the grocery store.
baking soda– Baking soda helps the cookie bars rise during baking.
kosher salt– Kosher salt is a course salt commonly used in cooking and baking. I prefer it over table salt.
mini chocolate chips– Find mini chocolate chips near the regular chocolate chips in the baking isle.
mini Kit Kat Bars– Find mini or regular size Kit Kat bars down the candy isle of your grocery store.

How To Make Kit Kat Bars

Preheat oven to 350 degrees F. and line a 9 x 13 inch baking dish with parchment paper.
Place butter and sugars into a large mixing bowl or stand mixer.
Beat until creamy and well combined. Add eggs and vanilla stirring well to combine.
Slowly add flour, pudding mix, salt, and baking soda. Stir until dough forms then add chocolate chips to combine.
Transfer dough to baking dish and press evenly into dish.
Top with Kit Kat bars and bake for 35-38 minutes or until baked through. Remove from oven and let cool completely before cutting into squares. Serve warmed or at room temperature.

Tips For Making The Best Cookie Bars

Don’t alter the recipe, use all ingredients as listed.
Always use butter, not margarine. ALWAYS. I prefer salted butter for my chocolate chip cookies. Try it!
Don’t skip creaming your butter and sugars for a good 1-2 minutes. Helps create a fluffy, chewy cookie bar.
Try sprinkling dough with just a touch of salt for a perfect sweet and salty combination.
Don’t overtake your cookie bars. Bars will continue to cook on hot cookie sheet when removed from oven.
Let cookies cool completely before cutting into squares and storing in containers. This will keep their crispness.
Store leftover cookies in an airtight container for 3 days room temperature.

How To Serve

Serve Kit Cat Bars for any occasion that dessert is needed. Room temperature is best.

How To Store Leftovers

Store any leftovers in an airtight container for up to 3 days. Does not need refrigerated.
