Make DIY Cookie Paint with Marshmallows

Another week of quarantine, another week of trying to figure out ways to entertain these kids. Don’t they know mommy is tired????

I made and flooded cookies this week, but I must have been having an off day, because I had several that came out wonky. Runny icing, air bubbles, cratering. The trifecta.

If you’re a cookier, I’m sure you’ve know what I’m talking about. If you’re not a cookier....well, you probably wouldn’t have noticed anything, but I did, and that’s what mattered here.

My kids are always asking to help me decorate cookies, so I thought this would be an easy way to throw them a bone while also using up my mistake cookies.

I had read a while back about a simple way to use marshmallows to make edible paints, so we decided to try our hand at it. It was so easy (and delicious!), and the kids wanted to keep painting long after my cookie catastrophes were gone. So I popped open the tub of plain sugar cookies I had bought at the store last week (sacrilege, I know, but a momma’s gotta do what a momma’s gotta do), and we painted on those as well.

  • 15 regular-sized marshmallows (not minis)
  • 1/4 cup water
  • 3 Tablespoons light corn syrup
  • Food coloring
  • Mini paintbrushes (or something to “paint” with—Maddie was using her fingers at one point 🤷🏻‍♀️)
  • Cookies, iced or plain (it works better if there’s not a lot of loose sugar on top, though)



  • Place marshmallows in a microwave-safe bowl and microwave for 30 seconds.
  • Add water to the melty marshmallows and stir. Pop the bowl back in the microwave for another 30 seconds, and stir again for a minute or two. If you still have chunks of unmelted marshmallow, microwave for another 15 seconds or so.
  • Stir in the corn syrup until everything is nice and smooth. Separate into bowls and add a drop of food coloring to each bowl. Stir, then paint cookies!

Sophie was more precise with her painting, while Maddie went full-on finger paints. Soph also decided to try a pour technique towards the end, when the paints were running a little low.

The kids were really only restrained by their level of imagination and how sticky exactly I was willing to let my kitchen (and them) become 😂


Storing this Icing:

This paint will remain sticky for a couple of days! So it's best eaten right away.

You can store this paint in the fridge, in an airtight container, for a couple of days. You may need to microwave it again for 5 seconds at a time, stirring in between.
