Make a miniature Black Forest cake from polymer clay

What you'll make

Coco's miniature Black Forest cake tutorial makes a tiny cake that looks edible but is polymer clay from the base to the cherries: a baked clay base, glossy cherries on wire stems, chocolate crumbs and piped clay cream. Below are the step times, the products from the video and the numbers Coco gives for each step.

The Amazon links are paid links (see the disclosure above). The 3D printable cake stand shown at the end of the video is Coco's own file: an instant download from this shop that you print yourself.

You'll make: a tiny 1/12 scale Black Forest cake, about 3 cm (1.2 in) across, made entirely from polymer clay and shown on a 3D printed cake stand.

1. Tiny cake, all clay0:00 in the video on YouTubeA first look at the finished miniature cake. Every part of it is polymer clay.
2. Let's get started: what you need0:39 in the video on YouTubeCoco shows the supplies before the first step.
3. Step 1: The cake base1:01 in the video on YouTubeRoll white FIMO Soft clay as thick as your 3 cm cutter is tall (2 cm) and cut the base. Bake it at 230°F (110°C) for 30 minutes under a foil archway that does not touch the clay.
4. Step 2: The cherries2:03 in the video on YouTubeMix 6 parts red, 2 parts dark red and 3 parts translucent clay. Roll a 2 mm stick, cut 7 mm pieces, roll them into balls and poke a deep hole in each. Pre-bake the cherries for 10 minutes under foil.
5. Step 3: The wire stems2:52 in the video on YouTubeCut thin, flexible beading wire (0.46 mm) into 8 mm pieces and curve the tip. Paint the stems green with a touch of brown and let them dry for at least 30 minutes.
6. Step 4: Chocolate crumbs3:39 in the video on YouTubeRoll a 1 mm brown stick, press it onto paper and scrape it with a knife. Keep the crumbs under 2 mm, in mixed sizes.
7. Step 5: The piping cream4:22 in the video on YouTubeMix 1 teaspoon of FIMO Soft with 25 drops of clay softener, adding 5 drops at a time. Too hard to push? Add softener. No shape? Add more clay.
8. Step 6: Piping practice5:07 in the video on YouTubePractise the piping before you decorate the cake. Coco suggests doubling the cream recipe so you have enough to practise with.
9. Step 7: The base cream6:06 in the video on YouTubeThe base cream is about 1 mm thick, thinner and more flexible than the piping cream.
10. Step 8: Cover the cake6:33 in the video on YouTubeCover the baked cake base with the base cream.
11. Step 9: Roll in the crumbs7:14 in the video on YouTubeRoll the cake in the chocolate crumbs so they stick to the cream.
12. Step 10: Pipe and fill7:45 in the video on YouTubePipe the cream onto the cake.
13. Step 11: Cherries on and bake8:34 in the video on YouTubePlace the cherries on the cake and bake the finished cake for 10 minutes under a foil archway. Do not overbake it, or the cream turns yellow.
14. Step 12: Glaze the cherries8:57 in the video on YouTubePut a small drop of glaze on the brush, not on the cherry.
15. Step 13: The stems9:33 in the video on YouTubeFix the wire stems with instant glue in a well ventilated room. It sets in 30 seconds.
