Found the recipe for these cupcakes at Call Me cupcake. It's a very inspiring swedish blog with lots of beautiful pictures and great recipes. On the site it's listed in cups, so here ir is in grams.
Banana cupcakes
- 28 cupcakes
•270 g siftet all purpose flour
•1 1/2 teaspoon baking soda
•3/4 teaspoon baking powder
•3/4 teaspoon salt
•1 teaspoon powdered cinnamon
•170 g soft, unsalted butter
•300 g brown sugar
•3 large eggs
•4 very ripe, large bananas, mashed
•180 ml buttermilk
•1/2 teaspoon vanilla extracts
•120 g chopped pecan nuts (optional)
Notes: If you use salted butter, then leave out the salt, you otherwise need to add. If you don't have buttermilk you can make a good substitution by adding lemon juice to the milk. The mixture proportion is 1 tablespoon to 250 ml milk.
1. Preheat the oven to 175°C (350°F) and prepare the muffin tins with liners.
2. Mix the dry ingredients in a bowl.
3. Mix bananas, buttermilk and vanilla in another bowl.
4. Beat together butter and sugar, after which eggs are added one at a time.
5. Add the dry and the wet ingredients to the butter in 3 round, starting and ending with the dry.
6. Fill the liners and bake for 15-20 min. Let them cool completely before frosting them.
These cupcakes are really moist and stay this way for several days. I didn't add the nuts, but I think they would only make the cakes better.
Caramel frosting
This frosting is a Swiss meringue buttercream and it can be a bit heavy but has a incredibly delicious consistency and taste.
•6 egg whites
•240 g granulated sugar
•270 g soft, diced butter
Salted caramel to your liking.
1. Pour egg whites and sugar in a clean and heat proof bowl. Put the bowl in a double boiler, the water should be simmering. Whisk the sugar end eggs constantly so they don't curdle until the sugar is melted. Rub some of the mixture between your fingers to see if it's done.
2. Remove from heat, whip until white, fluffy and cool. This step can take up to 10 minutes.
3. Start adding the butter, very slowly. One dice at a time and wait with the next until the other one is fully incorporated. At some point it will look curdled, put just keep whipping - it will get smooth. If it is a bit runny, put it in the fridge for at little while and continue whipping.
4. Add caramel to the buttercream and whip until smooth.
