Robby’s Winterfest Baking #16

  The “baking therapy” discussed on this blog refers to my personal experience using baking as a self-help and relaxation tool.”

Hey, Everybirdy! Welcome back to the nest.

Today, we are making a batch of Oreo Cookie Coal. I thought this would be such a fun “prank” gift to give my family on Christmas Eve—a playful way to tell your loved ones they’re on the “naughty list” until they take a bite and realize it’s actually a delicious, chocolatey treat!

Beyond the laughs, there is something deeply therapeutic about this recipe: taking out a whole package of cookies and crushing them into pieces is the ultimate physical stress release after a long day. It’s a gentle reminder that baking therapy doesn’t always have to be serious or formal—sometimes the best comfort comes from a lighthearted, no-bake treat that clears your mind and brings a smile to everyone’s face.

Before we jump in, you can read my personal updates, deep dives, and exclusive sneak peeks of my upcoming book over on Substack.


The Essentials

You only need three basic pantry staples to make this “coal”:

  • 1 Package (20 oz) Chocolate Sandwich Cookies (like Oreos): Crushed into coarse, coal-like chunks.
  • 1/4 Cup Butter or Margarine: Melted to create that silky marshmallow base.
  • 1 Package (10 oz) Mini Marshmallows: Binds the cookie crumbs together into soft, chewy shapes.

Let’s Get Baking

  1. Crush the Cookies: Place your chocolate sandwich cookies in a large sealable bag. Use a rolling pin or meat mallet to crush them into a mix of small crumbs and rough chunks so they resemble real pieces of coal.
  2. Melt the Base: In a large pot or saucepan over low heat, melt your butter or margarine. Add the mini marshmallows and stir continuously until smooth and completely melted.
  3. Combine: Remove the pot from the heat and immediately fold in your crushed cookies. Stir gently until every piece is coated in the sticky marshmallow mixture.
  4. Shape the Coal: Line an 8×8 baking dish with parchment paper (or grease lightly). Press the mixture evenly into the pan, or use greased hands to shape individual, jagged “coal lumps” on a baking sheet.
  5. Set & Serve: Let the treats cool completely at room temperature for about 20 to 30 minutes to set before slicing or breaking into chunks.

Questions & Answers

How do I get the “coal” look without turning it into mush?

Keep some larger cookie chunks intact when crushing! Having a mix of fine crumbs and jagged 1/2-inch pieces gives the treats an authentic, rough coal texture once coated in marshmallow.

Can I make these in advance?

Yes! Cookie coal keeps wonderfully at room temperature in an airtight container for up to a week. They make great make-ahead holiday party treats or stocking stuffers.
