Naughty or Nice?

Although nobody wants to get coal for Christmas, one bite of these glittering lump of coal brownies and you and all your family and friends will want more! Plus, they’re pretty easy to put together! 

These amusing brownies will most certainly put a smile on even the naughtiest! Perfect as a gift (find those little stockings at craft stores and fill!) or bring as a fun party dessert.

Or, I thought I’d have a little fun this Christmas and make some different sweet treats for my family! My little four-year-old is into the coal concept, naughty vs. nice, this year so I thought I’d have a little fun and make these naughty coal brownies! I’ll have to stick a few in his stocking and record his reaction! Aside from how they look, (although I personally think they’re quite stunning enrobed in the sparkling black sanding sugar) they’re extra delicious.

A note of caution: they are rolled in black sanding sugar, so get those toothbrushes ready. Aside from that, it’s a fun little treat and moment for Christmas!

Let’s Start Making Lump of Coal Brownies

They’re easy to make! Here are the components: 

  • Brownies
  • Chocolate Icing
  • Black Sanding Sugar

To make, just make a dark chocolate, dense brownie. Keep scrolling down and you’ll find my favorite brownie recipe (it’s pretty amazing!) or feel free to make your own recipe or even a box mix! Then ice with a chocolate icing made of butter, powdered sugar, a bit of milk and cocoa. OMG…what could be better? Sprinkle with the sanding sugar, cool and cut into “coal” looking pieces. Then to finish the look, completely coat all the other sides in the sanding sugar.

Note: the icing dries hard, so make sure to sprinkle the top of the brownies with the sanding sugar while the icing is still sticky. Then cool. 

Brownie Time

Step 1: To make the brownies, start by melting the butter.
Step 2: Once it’s melted, add the oil, eggs, granulated sugar, brown sugar and vanilla.
Step 3: To this add the dry ingredients, flour, cocoa and cornstarch. Mix just until everything is combined.
Step 4: Pour into a greased and parchment-lined 8×8 inch pan (I like thicker brownies, but a 9×13 inch pan will certainly work as well) and bake for 25 – 35 minutes. The middle will still be a bit sticky, but that’s how you’ll want them to be. Ooey, gooey, crazy delicious!

Icing Time

Step 5: Next make the icing. Start by melting butter.
Step 6: Then to that add the cocoa, milk and powdered sugar. Stir together until completely smooth.
Step 7: Immediately pour and spread on the brownies. Add a generous amount of black sanding sugar and cool completely. I placed mine in the refrigerator to speed the process up.

“Coal” Time 

Step 8: Once they’re cool, cut into “coal” shapes. There is no rhyme or reason, just make them look like rocks. Cut square pieces and misshapen them a bit.
Step 9: Then roll them into the black sanding sugar immediately. Don’t let them dry out or the sanding sugar won’t stick properly.
