Mix the liquid ingredients in one bowl (milk, egg, oil, vanilla) and the dry ones in another (flour, yeast, sugar, salt, chocolate chips, leaving a few drops of chocolate aside for decoration).
Pour the liquid ingredients over the dry ones and mix quickly, then also incorporate the peanut butter, always coarsely (in this way some veins will remain and the taste will be slightly more intense).
Spread the mixture into the cups, filling them 3/4 full, decorate with the leftover chocolate chips and bake for about 15-20 minutes at 200 ° C, in a pre-heated ventilated oven.
The peanut butter muffins are ready, let them cool before turning out and serving.
