To make the cupcakes - pre-heat your oven to 160C/320F. Line your cupcake tin with cupcake liners or grease your cupcake tin with non-stick cooking spray. Set aside.
In a medium-sized bowl, sift together the flour, cocoa powder, baking soda and salt. Add the sugar to the sifted ingredients, and mix well with a whisk. You want the mixture to be uniform in colour, without any white or dark brown streaks. Finally add in your chocolate chips, then set aside.
In a large-sized bowl, mix together the cooled coffee, oil, buttermilk and 3 eggs. Whisk together until well combined.
Now that you have one dry mixture, and one wet, you will need to combine them. The best way to do this to ensure your cupcakes aren’t tough, is to add the dry mixture to the wet and slowly whisk it together to combine.
Once everything is mixed together, pour the batter equally into the cupcake lined tin and bake for 22-24 minutes. The cupcakes are baked with a toothpick placed in the center of one of the cupcakes comes out clean.
Allow the cupcakes to remain in the tin and cool on a baking rack for about 10 minutes before removing them from the tin. Allow them to cool completely before piping with frosting.
To make the frosting - unwrap the Kvik Lunsj and add them to a large zip top freezer bag. Roll and smash the candy bars until they resemble sand. Set aside.
Add the butter to the bowl of standing mixer fitted with the K or paddle attachment. Whip on medium-high speed until light and creamy, about 2 minutes. Add the powdered sugar to the bowl and mix until fully incorporated. Scrape down the sides of the bowl as necessary, to ensure all the butter and powdered sugar is incorporated.
Add the vanilla pod seeds and salt into the bowl. Mix until combined. Next, add the cream and vanilla extract. Mix again until combined.
Increase the mixer speed and whip the frosting on high speed until light and fluffy, about 5 minutes. Add the crushed Kvik Lunsj and mix until just combined.
Pipe frosting onto cooled cupcakes and add decorate cupcakes with smaller pieces of Kvik lunch as garnish.
