Pre-heat your oven to 160C Fan/350F/Gas Mark 4 and line a cupcake tin with paper cases
To make the chocolate sponge mix together the butter and the caster sugar, ideally using an electric mixer, until fluffy
Add the eggs and milk, and mix them in
Mix in the self raising flour, cocoa powder and baking powder gently with a hand whisk
Divide the cupcakes between the cases and bake them for 20-25 minutes
When they are fully cool use a cupcake corer or a knife to remove a section from the middle of each cupcake
Fill each hole with the caramel sauce, you can use a piping bag to do this, or simply spoon it in
Make the buttercream by mixing together the butter, icing sugar, cocoa powder, milk and vanilla extract. Use an electric mixer for the best results. Then add the melted Galaxy chocolate and mix until smooth. If the buttercream is too stiff, you can add a little extra milk
Pipe the buttercream onto each cupcake to resemble a nest (pipe a flat rosette, then pipe a ring on top of it with space in the middle for the chocolate eggs) then place 3 Galaxy Enchanted Eggs into the middle
Store in an airtight container in a cool place, eat leftovers within 3 days
Notes
Make sure all your ingredients (particularly the butter and eggs) are at room temperature before you start baking.
I used a baking spread for the cupcakes and unsalted butter for the buttercream.
For the filling, my favourite caramel sauce to use is my Homemade Caramel Sauce. But you can also use a shop bought sauce.
I've decorated the cupcakes with Galaxy Enchanted Eggs - they are very widely available in the UK but you can use any chocolate eggs and spray them with an edible metallic spray instead if you can't find them.
If you don't want to use Galaxy chocolate for the buttercream you can use another type of chocolate.
Although I provide cup measurements, I highly recommend weighing your ingredients out using digital kitchen scales*. It is the most accurate way to measure ingredients and will ensure the best results. Digital scales are very low cost and can be purchased for around £12 ($16.50) .
For teaspoon (tsp) and tablespoon (tbsp) measurements, please use measuring spoons* and not the type of spoons you eat with. Again this will ensure accuracy and provide the best results.
