Recipe FAQs: Galaxy Chocolate Cupcakes

I live in the US, is Dove the same as Galaxy?

Yes it is. Apparently they taste identical. A bit of trivia for you, Dove was introduced to the UK as Galaxy in 196O. Don’t ask me why they changed the name though 😅

What size cupcake cases should I use?

Cupcakes come in three sizes; fairy cake, standard and muffin. The baking time will vary depending on the size you use. This Galaxy chocolate cupcakes recipe will give you 12 muffin-sized cupcakes. The cases I used measured 2″ base and 1.5″ deep.

How do I know when the cupcakes are baked?

These Galaxy chocolate cupcakes will take 18-20 minutes in the oven at 180°C. The cupcakes should have a nice rise to them, be dark brown in colour and if you insert a toothpick into the centre of a cupcake, it should come out crumb-free.

What can I use to scoop out the middle of the cupcake?

The easiest way is using a cupcake corer like the one in the photo below from Joie. You can also use the round base of a large piping nozzle or a teaspoon to scoop out the middle.

My Galaxy chocolate ganache is too thick, what should I do?

This can be due to a number of reasons. Either the cream was too hot or too cold, you over-stirred the ganache or the chocolate wasn’t chopped small enough. Ganache can be very temperamental 🙄 But don’t worry, your Galaxy ganache can be saved!

Place the bowl over a pan of simmering water, making sure the bottom of the bowl isn’t touching the water. Gently stir until the ganache warms up and starts to melt. Remove from the heat once you’re happy with the consistency.

How do I pipe buttercream swirls?

  1. Fit a large piping bag with a large open star nozzle and fill with Galaxy chocolate buttercream.
  2. Hold the piping bag upright at the outer edge of the cupcake.
  3. Apply pressure to the top of the piping bag and pipe in a circular motion spiralling inwards and upwards at the same time.
  4. To finish the swirl, release pressure and gently lift the piping bag up.

Make the Galaxy chocolate ganache and fill the cupcakes

  • Finely chop the Galaxy chocolate (the smaller the chunks the better) and place in a glass bowl.
  • Heat the cream in a small saucepan set over low heat until it's piping hot, but not yet boiling.
  • Pour the hot cream over the chocolate and leave to sit for 20 seconds. Now slowly stir until the chocolate melts and the ganache is smooth.
