Load into the Thermomix or stand mixer, your butter and sugar and mix on speed 3 for 3 minutes.

Scrape the sides and add the vanilla and the eggs mix on speed 3 for a further 3 minutes.

Then add the flour and mix on speed 4 for 1 minutes. Then scrape the edges.

Load the cupcake batter into paper cases to ¼ full and then inside your small pudding dishes.

Load into the air fryer and cook for 12 minutes at 160c/320f. Allow to fully cool on a cooling tray. Whilst they are air frying clean the Thermomix and then make your buttercream.

Then once the cupcakes are cool, slice a circle around the tops and remove the centre, making sure you don’t go too low. Then slice these cake pieces in half lengthways.

Next load the nozzle into the piping bag and the piping bag over the drinking glass. Add the buttercream and use your hands to tightly twist the piping bag and add a peg to the top. Cut the bottom off the piping bag so that the nozzle comes through.

Pipe your butterfly bun holes.

Then place the two slices of bun over to form a butterfly.

Then sprinkle with icing sugar before serving.
