Pre-heat the oven to 350 ºF – 180 ºC. And line a muffin pan with cupcakes liners.
In a large bowl, beat the eggs in a stand mixer until foamy and start adding little by little the sugar. Incorporate the orange zest. The amazing scent is SO delicious.
In a small bowl mix four and baking powder.
Now start adding the flour, oil and orange juice in small batches. First a few spoons of flour then a bit of oil and then a bit of orange juice until you have added all. Mix for about 1 more minute and turn the mixer off. The batter will be thin, so don’t worry.
Now pour the batter evenly for 12 cupcakes and add some chocolate chips to each cupcake batter.
Bake it for 30 minutes {sometimes it takes a bit longer so keep an eye on it}. The cake will rise a lot, sometimes it’s scary, we may think it will come out of the pan but it’s ok, once done and out of the oven it will shrink a bit.
Make sure you don’t open the oven before 30 minutes, this batter is very sensitive LOL. After that time you can insert a tooth stick and check if it comes clean or not. If it comes clean they are done!
Once done let it cool completely in a cooling rack..
For the frosting
With a stand mixer and a whisk attachment, whip the butter for 3 minutes over medium-high speed and add the cream cheese. Whip for 2 more minutes. Scrap the bowl at least one time during those 5 minutes. Add the powdered sugar little by little on slow speed and add the vanilla and salt scraping the bowl once. Add the Nutella and whip it again at medium high speed for 2 more minutes on slow speed. The mixture should be light and fluffy. Let it set for a few minutes on the fridge.
Decorate the cupcakes as you like. I also used a little bit of chocolate sauce as topping.
Serve and enjoy!
