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 want to make this recipe so badly but I looked everyone (even online!) and they don’t sell malted milk powder by Carnation anywhere here! Is there anything I can use instead? Would plain old milk powder do?

  2. northern cottage

    serious yum factor!! can’t wait to whip some of these babies up…thanks so much for sharing!

    I made these for some friends today, and I can report they are as amazing as they look. Probably the best brownies I have ever eaten. Although the servings say 9, better cut them a little smaller. They are very rich. You can always go back for seconds. 🙂

  4. Emma

    Ever since someone posted these on my tumblr a few days ago I swear I’ve dreamt of them. Tomorrow is my last exam and I will celebrate by going to the grocery store and getting whatever I need to bake these ASAP! They look so amazing!

  5. Melissa @ Treats With a Twist

    I’ve just developed a love for malt over the last two years, and I’ve been playing precious catch-up ever since 🙂 These look amazing. Do you get your mini white chips from King Arthur Flour?

  6. Natasha

    I just made these but I changed the recipe slightly as I didn’t have any malt milk powder. I used Milo, a malt chocolate instead so they were even richer. So so so good! Your ideas are incredible!

    Hi Jenny! I want to make these this weekend but I’m having trouble finding the Marshmallow bits and the malted milk powder. I went to our local Tom Thumb but either I was looking in the wrong place or they didn’t have it. Any suggestions?

  8. Jen @ Jen's Favorite Cookies

    Beautiful! I have a feeling these are going to be a hit with the family.

    The next time I want to buy something and I think the hubs is going to say no, I’m seducing him with these malted bars. Malted anything is a huge weakness for him!

    I had to laugh when I saw the stationary blob of dough sitting in the baking pan. It looks like the dough is merely a vehicle to hold all the goodies together. 😉

    How do you achieve the perfectly cut bars? The only time I got bars that looked that good was when I froze the finished product for about 20 minutes. Yours look like they are still slightly warm and gooey from the oven.

    These look insanely delicious! I love anything malted. I’ve still never seen those little marshmallows in the store. I’ll have to look closer new time. Nice one, Jenny!!

  12. Cookin' Canuck

    These look irresistible. My kids would be giving me multiple hugs and kisses if I made these.
