Poro Biscuit | League of Legends | Cosplay Prop Tutorial


Poros are wondrous little creatures from the League of Legends universe who LOVE biscuits! In this tutorial, I’ll show you how to create your very own Poro Biscuit using insulation foam.


  • Paper
  • Pencil
  • Scissors
  • Insulation Foam
  • Box Cutters (4-5 on hand)
  • Sandpaper (low grit & high grit)
  • Mod Podge
  • Paint Brushes
  • Acrylic Paints (Dark Brown, Light Brown, Black, White)

Step 1: Create a template


Create a template using any scrap paper you have on hand that will fit your design. For reference, my biscuit is about 3 inches wide.

After you have drawn your desired swirl, cut the template out. Cut along the edge of each swirl, so your template is line a wound up snake.

Step 2: Trace template onto insulation foam


Trace your template onto insulation foam. I used a pencil to indent my template into the insulation foam.

Steph 3: Carve, carve, carve!


It’s now time to start carving! Using your box cutter, carve away pieces of your insulation foam until you’ve achieved the desired shape. The outer layer should be the shortest layer, while the inner swirl should be the highest point.

Take your time. Every now and then take a step back and look at your work to make sure you are not carving away too much.

It’s also much easier to carve with a sharp blade. So have several box cutters with fresh blades or a sharpener on hand.

This is a messy process, so have a trash bag near by to throw away your scraps.

Step 4: Sandimg_0320

Use a low grit and high grit sandpaper to create a smooth working surface.

Step 5: Prime with Mod Podge


Prepare the biscuit for painting, by coating the biscuit with 2-3 coats of Mod Podge.

Step 6: Paint, paint, paint!

Using a light brown paint, give your my biscuit a base coat. I did 2 coats, letting the paint dry between each coat.

Next, mix the light brown with white paint,  and paint over the center portion of each ring. This will add dimension to the high points of the biscuit, making those portions look more raised.

Paint over the inner crevices with dark brown and black paint to mimic shadows and give your biscuit more dimension.

Add more white paint to the high points, and feather out the paint. Adding this additional white layer looks like a sugar glaze!

Finally, it’s time to add signature chocolate swirl. Using a very dark brown paint (mix dark brown and black paint together), paint a thin line along the curves of the biscuit.

Clean up any edges if necessary.

Step 7: Seal with Mod Podge

After the paint has dried, paint 1-2 coats of Mod Podge over the biscuit to protect the paint job.



With that, you have a super delicious looking but probably not very delicious tasting Poro Biscuit! If you end up using this tutorial, I’d love to see the results. 🙂
