Preheat the oven to 180 degrees.
Sift the baking powder and flour into a bowl so that there are no air holes in the dough.
In a second bowl, mix the eggs, vanilla sugar, sugar and salt.
Melt the butter and stir it in.
Finally, mix in the Bailey’s.
Mix the two mixtures together in quick puffs, by no means mixing together until fluffy.
Place muffin paper cups in a muffin pan, fill 2/3 full with the mixture and press a caramel into each cup.
Bake for about 20 minutes and then let cool slightly and remove from the molds.
