Made by Manu: A Warm Hug for a (Cookie) Mug


Even though I am now living in Thailand where it is currently 85°F (29°C), I haven't forgotten the cold of winter, which many of you are now experiencing. So, I thought, what better way to get cozy than with felt warmers on hot cocoa (cookie) mugs?! I used colored icing sugar (aka confectioner's or powdered sugar) for the felt effect. But right before coating the dried royal icing surface with the sugar, I used a paint brush to apply random dabs of flooding-consistency royal icing. I wanted some underlying texture because felt isn't as smooth as velvet or suede. And, just in case that texture wasn't enough to convey "felt", I added other little details typically used in felt crafts, like the icing blanket stitch along the warmer's edge.

I designed and hand-cut the mug cookies, but any mug cookie cutter can be used. I then designed the felt warmer, but it only took a click online to later find out that very similar designs had already been used in the “felt world” and the “knit world” . . . at any rate, I hope you enjoy this edible cookie rendition!

What you’ll need for this project:
  • Icing sugar, aka confectioner's or powdered sugar (A couple of tablespoons is more than enough to cover two mugs of the size shown here.)
  • Red and black gel food coloring (I used Colorgel by Modecor, but any gel coloring should do. Avoid liquid colorings.)
  • Food-grade plastic bags
  • 2 (3 1/2 x 2 1/2-in/9 x 6.5-cm) mug-shaped cookies (one a mirror image of the other), flooded with white royal icing and completely dry (You’ll find my mug cookie template and all measurements in "Attachments" under "Files" at the end of this post. But, again, you could use any mug cutter. A dark cookie dough is preferred for reasons you'll see in Step 2.)
  • Royal icing and pastry tips:
    • Red and grey piping-consistency with PME #1 tip or equivalent
    • Red and grey flooding-consistency with Wilton #2 tip or equivalent (Keep this icing on the thick side. A thicker icing will lend more texture to the warmer in Step 2c and also help prevent craters in the transfers made in Step 3.)
    • White very thick consistency in parchment cones (@Julia M. Usher calls it “glue” in her video, and I like to call it “Julia’s glue”.)
  • Large round paint brush(es)
  • Parchment paper
  • Tea strainer or fine-mesh sieve
  • Heart templates (Also under "Attachments", in the same file noted earlier.)
  • Scribe tool


Step 1: Tint icing sugar

Both red and grey icing sugar are needed for this project. If you can't find tinted icing sugar [EDITOR'S NOTE: I've never seen it! ], you can easily tint it yourself:

a. Put a tablespoon of icing sugar and a drop of red gel food coloring in a food-grade plastic bag. Get another bag, and repeat this process, this time using a drop of black gel food coloring.

b. Massage the bags until the icing sugar has absorbed all of the food coloring. Add more coloring if necessary - however, not too much, or your icing sugar will become kind of pasty. Also, be patient, because the icing color will "develop" and get a bit darker as it sits. To allow the color to fully develop, you can tint the icing sugar the day before you intend to use it, just as you might do with royal icing. (Note: It will take longer to get a deep red; the black coloring will make grey sugar almost immediately.)

c. The tinted icing sugar is ready.


Step 2: Decorate mug warmer

a. Set one of the iced (and completely dry) mug-shaped cookies on your work surface. (I left a section naked at the top in order to give perspective and dimension to the mug, and to resemble the hot cocoa inside.) Using red piping-consistency royal icing and a PME #1 tip (or equivalent), outline a band across the midsection of the mug. Give the upper and lower edges a curve to suggest the contour of a mug.

b. Flood the band with red flooding-consistency royal icing using the equivalent of a Wilton #2 tip. Let the icing dry completely.


c. Dip a large round paint brush in the red flooding-consistency royal icing, and apply the icing randomly to the red band with up-and-down motions of the brush.

d. The outcome is already nice, and we could stop here, but I prefer the more felty/woolly look imparted by the added coating of icing sugar. Now, mask the upper part of the mug with a piece of parchment paper (see arrow below), and quickly move on to the next step before the icing dries! (Note: I didn’t want the icing sugar, applied in the next step, to get stuck in the un-iced part of the cookie, which is why I masked it. In retrospect, it would have been better to mask all of the white areas before applying the red royal icing. Otherwise, there is risk of smearing the red on the white, as I did in the lower part of the mug!)


e. Use a tea strainer (or fine-mesh sieve) to sift the tinted red sugar onto the wet icing.

f. Let the sugar sit for a couple of minutes, and then shake off the excess. Let the icing dry.


Step 3: Prepare royal icing transfers

a. Place the heart templates under a piece of parchment paper. (Again, you’ll find both big and small heart templates in the attachment at the end of this post.) Trace the outline of the big heart and the three little heart buttons with icing. Use grey piping-consistency royal icing and a PME #1 tip (or equivalent) for the big heart and two of the buttons. Use red piping-consistency royal icing and a PME #1 tip for the remaining button. Make sure to pipe two small holes in each of the button transfers.

b. Flood the heart shapes using grey and red flooding-consistency royal icing and Wilton #2 tips (or equivalents). Use a scribe tool to work the icing into the tiny corners. Let the transfers dry completely.


c. Use the grey piping-consistency royal icing to pipe a stitch on the red heart button (to connect the button holes), and do the same for the two grey buttons with the red piping-consistency royal icing. Again, use PME #1 tips (or equivalents) for this step.

d. Using a clean round paint brush, dab the grey flooding-consistency icing on the big grey heart, and coat it with grey icing sugar, just as we coated the mug warmer band in Steps 2c to 2f.


Step 4: Add details to mug warmer

a. Use grey piping-consistency royal icing and a PME #1 tip (or equivalent) to pipe a blanket stitch along the upper and lower edges of the warmer. Basically, a blanket stitch looks like a series of right angles: _|_|_|. So just pipe a string of horizontal and vertical dashes.

b. Use a dot of “Julia’s glue” to attach the grey buttons close to the mug handle. (In real life, these buttons would hold the warmer in place.) Glue the red button on top of the big grey heart transfer, and then attach the entire piece to the center of the warmer.


Repeat Steps 2 to 4 for the second mirror-image cookie mug, but invert all of the colors.

Our two Valentine’s mug cookies are now ready, hugged in warm felt and displayed on a felt place mat. [EDITOR'S NOTE: Wow! I can hardly distinguish the real McCoy from the faux-sugar felt!]


Add some mini marshmallows to the mugs, and some letter cookies decorated with the same felt technique, and you've got a cute Valentine’s-themed cookie platter!


Happy Valentine’s Day!

Speaking of Felt in the Cookie World

Joss Lewis of @Former Member took another approach to making "felt". He simply used tinted cookie dough, and the effect is quite realistic, as you can see in his set of carrot cookies here.

Rocio Cuenca, known as @Little Wonderland, left the cookie world one year ago to learn sewing. I miss her beautiful cookies, but she keeps being creative with her new medium. Here’s a bunny cookie that she made as a cookier, and here is the new version of that bunny in felt form (hand-sewn).

Manuela Pezzopane, affectionately called Manu by her friends and family, is a fan of everything handmade, and professes to have tried every possible hobby. However, it wasn’t until the end of 2014, when an American friend invited her to a Christmas cookie exchange, that she first discovered decorated cookies. In 2015, after watching Julia M. Usher's videos and signing up on Cookie Connection, Manu finally attempted her own. Since then, cookie decorating has become Manu’s passion. You can follow Manu on Facebook and Instagram, or email her at

Fabulous tutorial @Manu biscotti decorati!!! I just love the idea of creating something "warm" for winter. And these mugs couldn't be more perfect dear Manu ❤❤❤. As always you've taken a very unique,  creative way to make these mugs 😊. The look of felt is wonderful!! I also love how you've made buttons out of the heart transfers that can be "stitched" onto the mug.  I'll have to give this a try,  with your permission,  of course!! 

Every tutorial of yours is my fav tutorial of yours 😂 I am in awe with this set, so brilliant and perfect for winter time. I am sure this great felt technique on cookies is going to become a new trend! Fantastic ❤️

Thank you so much, Carol @Cookies Fantastique.

Of course! You don’t need my permission ! What I share here is for free fruition... I would just really appreciate a shout out ☺️☺️☺️: tag and a link to the tutorial here on Cookie Connection when someone gives a try to my tutorials. I know very well all of your posts though and I know that you’re the one who never fails to give credit or to cite your sources of inspiration 💕

I like the buttons as well. I designed this project as if I was designing the real felt warmers. So the buttons were a way to hold the warmer in place and to decorate it. And of course the heart shape was the cutest.  But I also found out that Evelin @Evelindecora also used buttons in her cookies a few years ago. So a shout out to her would be appropriate!
