Dark chocolate cupcakes with cherry frosting

Hello there! Some days ago I decided to make a cupcake I previously couldn't find in any book. The result was this dark chocolate cupcake with cherry frosting. I think the end result turned out really delicious and now I'm sharing the recipe with all of you :)

Dark chocolate muffins (12st)

 Ingredients
125g unsalted butter
100g dark chocolate
a pinch of salt
2 eggs
1½ cup flour
1 teaspoon baking soda
½ cup sugar

Do this
1. Preheat your oven to 175°C.
2. Using a saucepan, melt your butter and dark chocolate and stir slowly. When both ingredients are fully mixed and melted you can take your saucepan of the heat and let it cool.
3. Mix salt, flour and baking soda in a bowl.
4. Beat the egg and sugar until they are white and fluffy in another bowl.
5. Mix the beaten eggs and sugar with the dry ingredients.
6. Add the chocolate and butter mix, stir until everything is well mixed and put the mixture into cupcake tins.
7. Bake for 20min and then let them cool while you make the frosting.

Cherry frosting

Ingredients
150g butter
100g cherry jam
2 cups icing sugar
1-2 drops cherry essence (optional but adds more taste)

Do this 
1. Beat the butter until it's smooth.
2. Add cherry essence and half of the icing sugar, then mix well.
3. Add in the rest of the icing sugar and the jam, mix well.
4. If your frosting is too hard, add a teaspoon of milk, if not you are done.
