Malted Chocolate Chip Cookie Bars

I always have so much fun creating new desserts, this bar was no exception. I LOVE malt flavor in my desserts so I knew this bar would be a huge hit. I used my Malt powder AND some crushed chocolate malt balls. Wait until you take your first bite, between the marshmallow bits and the malt balls, the texture is chewy and perfect.

Hope you enjoy!!

Here’s your line up!

How to Make The Best Chocolate Chip Cookie Bars

The stars of the show here! I had some Harry and David malt balls which are my favorite, but if you have just the good ol’ box of Whoppers, those will work too.

Break out your basic cookie ingredients.

I used some mini white chips, but regular white chips will work too!

Let’s cream the butter and sugars.

Add your egg.

…and some vanilla.

Slowly add your dry ingredients.

Add your chips and marshmallow bits!

Add some white chips

Crush your malt balls with a rolling pin, makes it nice and easy.

Add them right to the mix.

Time to mix!


Transfer to your baking dish.

Press nice and even.

Top with crushed malt balls and white chips.

Bake until deep golden brown and baked through.

 Let cool, cut into squares and eat!

    I made these yesterday (they looked so great) and the edges puffed up and were very hard, the middle was great!! Not sure what I did wrong πŸ™

    1. Jenny

      Hi Jane, I cut off about 1/4 inch of all sides because I don’t love the crispy edges. I had to save them though because my family loves them. If you cut them off the rest of the bars are fantastic!

    Would love to know if you use Picnik for photo collages?
    Have no idea how I’m going to create photo collages after Picnik shuts down.
