Undertale Temmie |

Henri is going to be 13(!!) on Saturday, so between now and then I’m going to share some of his past birthday cakes that haven’t hit the blog yet, with full tutorials for the ones that are possible. First up is this Tem Shop cake from his 8th birthday, back in 2017

The kids (and I, if I’m being honest) were bit hard by the huge phenomena that was Toby Fox’s Undertale. The name “Flowey” instantly evokes a bigger horrorscape than the trippy sequence in Fantasia, we use “determination” in more sentences than appropriate and often have Megalovania and the rest of the incredible soundtrack on repeat. For a while Henri’s favorite character was Temmie and in addition to adding “Hoi!” to nearly everything he said, he was determined to have a Tem Shop birthday cake.

A few days before his party I baked up 2 cakes in my usual way and set them aside so I could work on the fondant toppers.

I found a reference image from the game online:

Then I resized it to the scale of my cakes, using the baking dish as a guide.

The bottom third of the cake would be the black text box that’s always present on screen, so I scaled my reference image to fit 2/3 of the cake and printed it out.

I rolled out some white fondant onto my Wilton measuring mat, using my roller with spacers to get an even thickness. Then I used the blade tool from my gum paste tool set to carefully cut out each piece.

I set the pieces aside for a few days, flipping them over about twice per day, so they would harden. The more moisture that gets removed from the fondant prior to painting the better, since painting will add moisture and I don’t want the sugar to melt down.

Anytime I do fondant painting (ex: Minecraft cake, Charlie & Lola cake, Skylanders cookies, Montreal Canadiens cake) I always like to assemble all my supplies within reach. This includes the paintbrushes and palette I use exclusively for food, Wilton and AmeriColor gel colors, a small jar of vodka for diluting icing gels, toothpicks for getting the gels out of the tubs, plus icing sugar for thickening my homemade edible “paints”.

Gel colors dilute super easily, so a tiny dab on a palette is often all you’ll need for beautiful, rich colors.

I painted each piece to match its in-game counterpart. Most are easy enough to eyeball but if ever you’re not sure of dimensions you can sketch lightly over the reference with the tip of a pin and emboss guide lines into the fondant.

Once the pieces were touch-dry I prepared the cake itself. First I gave it a crumb coat.

Then I tinted some icing to match the wood background of the shop and applied it over the shop section of the cake, making sure to apply it thick enough to lightly carve into without reaching the cake below.

I used a toothpick to score lines for the wood wall then diluted some brown gel color and carefully flooded it into the grooves.

The final touch was to add some nail heads, and the wall portion was done.

After that I tinted icing black for the text box.

Pro tip: if you start with chocolate icing (instead of white vanilla) you’ll use much less black coloring, which will avoid any bitter taste in the icing.

I covered the remaining part of the cake in black, and then added the figures, and then finished up the outside and edges of the cake with white icing to clean everything up.

If you add the fondant toppers while the icing is still moist, they’ll stick in place without issue. If your icing has already started to crust over then you can paint a little bit of water on the back of the fondant and that will adhere it in place. Try to avoid getting too close to the edges with the water, so it doesn’t leak out around the edges and cause bleeding onto the base icing.
