Ingredients in Kit Kat Cookies

There are only a few ingredients in these Kit Kat Brownie Cookies, here they are:

• Fudge Brownie Mix-with so many ingredients you need to make cookies, this mix is the perfect place to start.
• Eggs-help add structure by binding the ingredients together.
• Vegetable Oil-adding the oil to the cookie dough adds moisture which keeps the cookies super soft once baked.
• All Purpose Flour-putting a small amount of flour to the dough adds a little more body which gives you cookies that don’t flatten out too much.
• Mini Chocolate Chips-I love semi-sweet chocolate chips in the mini version but any kind of chocolate chips would be delicious.
• Kit Kat Candy Bars-chopped down into smaller chunks and added to both the dough and to the top of the baked cookie, Kit Kats give a great crunch factor.

How to make Kit Kat Cookies with a Brownie Mix

Making Kit Cat Cookies with a Brownie Mix doesn’t get any simpler.  A few easy steps and you will have warm and wonderful cookies.

1. Unwrap all of your Kit Kat bars.
2. Chop each Kit Kat bar down into smaller pieces {I got 4-5 pieces per stick}.
3. Combine the cookie dough ingredients and mix together using a hand held mixer.  Add the mini chocolate chips and 2/3 of the Kit Kat bar pieces to the dough.
4. Stir the chocolate chips and Kit Kat pieces into the dough by hand until they are evenly distributed.

Use a medium cookie scoop to scoop mounds of cookie dough onto a silicone mat {or parchment} lined baking sheet.

Bake the cookies in a 350 degree oven for 9-11 minutes or until the cookies are set.  Take the remaining 1/3 of chopped Kit Kat pieces and place 3-4 pieces into the top of each cookie.

Remove from the oven and allow the cookies to cool on the cookie sheet for 10 minutes.

4 Tips for Making Kit Kat Cookies

• If your brownie mix has lumps then be sure to whisk it before adding the other cookie dough ingredients.
• Stir the chocolate chips and Kit Kat pieces into the dough by hand so that they don’t break down too much into the dough.
• Use a cookie scoop to ensure that all of the cookies are the same size and bake evenly.
• Don’t over bake the cookies and allow them to cool for at least 10 minutes on the baking sheet.  The residual heat from the baking sheet will continue to bake the cookies slightly and set them up perfectly.

Frequently asked questions about this Candy Bar Cookie

Can I make this recipe with other candy?

Yes!  Almost any kind of chocolate candy would work wonderfully.  Reese’s Peanut Butter Cups, Crunch Bars and Twix would all be extra awesome.

Just raid your Halloween candy bucket and make some cookies.  If cookies aren’t your thing then maybe this Halloween Candy No Bake Cheesecake is something you would like.

How do I store these cookies?

The best way to store these cookies is in an airtight container at room temperature for 3-4 days.

They can also be frozen for up to 3 months, just like these White Chocolate Macadamia Nut Cookies.

Can I make larger cookies?

Absolutely!  Just know that they can be a little rich.  If you would like a bigger cookie then use a 1/4 cup for the scoop and bake them for 13-15 minutes.

What makes a cookie chewy vs. cakey?

When using a brownie or cake mix this can get a bit tricky.  For a soft and chewy cookie make sure that you aren’t adding too much flour to the mix.  The less flour you add in addition to what is already in the mix will give you a much chewier cookie.  

The other important thing is to not over bake the cookies.  Pull the cookies from the oven when they are set up and then allow the cookies to cool on the baking sheet.  The residual heat from the baking sheet will set the cookie up perfectly without over baking them.

For a more cake like cookie, add additional flour and a bit of cornstarch to the cookie dough.  The flour is going to give a bit of a thicker cookie dough and the cornstarch will help lighten the cookies as you bake them.  Giving them more of a cakey texture.
