Cookies: Rainbow S’moreo Cookies

Original recipe:

I was in the mood to try something different, and I wanted something related to summer. I came across this recipe, and thought I would give it a try.

I tried making this once before, but I forgot the crucial step of flattening the cookies before baking them. I left them in balls, and wondered why they didn’t flatten, and then I realized my mistake. Plus, I didn’t photograph anything that I did, so I had to make it a second time, and correctly.

Let’s start off with the usual first step: combine butter and sugar.

Make sure your butter is softened.

After mixing them up for about a minute, drop in your egg and vanilla.

Happy cyclops?

After those are mixed up, add your cocoa powder and mix.

I almost ate this part, lol.

In a separate bowl, whisk together the graham cracker crumbs, flour, baking powder, and salt.

The usual fun of whisking the dry ingredients together.

Slowly pour in the dry ingredients into the stand mixer as it is running.

Raw Oreo cookie mix…

Next, you should refrigerate the dough for a while, about 30 minutes. This is actually necessary as you will need the dough to be scoopable, and be able to flatten it. If the dough hasn’t been refrigerated, this becomes very tedious.

It’s actually pretty chunky.

At this point, you will want to preheat the oven to 350F. Line two cookie sheets with parchment paper. Using your 1tbsp scoop that actually works, make some 1″ balls with it.

Something like that.

Next, using some small glass, dip the bottom in sugar and squish the balls of dough.

As it turns out, these cookies don’t flatten on their own…
They’re not perfectly pretty, but they’re going to be tasty!

Bake these in the oven for 10 minutes if you’re using an aluminum cookie sheet.

Baked and ready!

Let them cool for about 5 minutes before transferring them to your cooling rack.

Cooled down and ready for spreading!

Using marshmallow cream, spread it on the bottoms of half of the cookies.

This gets really messy…
It ain’t pretty…
Honestly, you could just stop here and make your own oreo cookies from here…

Make your cookie sandwiches with them. Using a bowl of sprinkles, roll the cookie sandwiches in it.

Don’t eat the sprinkles yet…
They definitely look homemade!
The utter magnificence!

There’s just one problem with using marshmallow cream…

It expands and gets really messy very quickly…

I think the cookies in this recipe are meant to be enjoyed right away, like an actually s’more.

Overall, this is a good recipe that requires some extra ingredients to make it happen. You’ll need some graham cracker crumbs as something extra to make this happen. Also, the marshmallow cream is extremely messy.

If I was to make this again, I probably would use a frosting for the filling, or make my own because the marshmallow cream is tasty, but extremely messy. Plus, it seems to continue to expand like crazy.
