4: Knead again on medium speed just until evenly mixed. Preheat oven to 180°C (360°F).
5: Divide the mixture between small moulds, preferably in paper cake cases. Do not over fill as the cakes will expand during cooking. You can divide out the mixture with a spoon, but it's much quicker and easier to use a forcing bag.
6: Put in the oven and bake for around 35 minutes (watch for colouring). Leave to cool on a wire rack.
8: Melt 150 g fondant icing in a bain-marie. Note: if you don't have fondant icing, make up a quick glacé icing using 100g icing sugar mixed with 1 tablespoon water, or just a little more.
9: Spread icing over the cupcakes...
10: ... and place a cactus on top immediately.
11: Decorate all the cupcakes like this.
Remarks
You can start with the basic cupcake mix and let your imagination run wild! A quick variation: replace the marzipan decorations with pistachio paste, which gives a more realistic saguaro cactus colour. For that real Arizona touch, the sun should make an appearance on the cupcakes, maybe as a small circle of yellow marzipan at the top to left or right of the cactus? Oh, well - for next time.
