In the bowl and an electric mixer, combine yeast, water, milk and sugar.
Stir to dissolve and let sit for about 5 minutes.
Add vegetable oil, salt and about 2 cups of flour.
Using the dough hook, mix at medium speed until the dough comes together.
Add the remaining flour a little at a time until the dough pulls away from the sides of the bowl.
Turn out onto a floured surface and knead for about 4 minutes (or let the mixer do it).
Place in a lightly greased bowl and cover with a towel. Let rise for 1 hour..
Once the dough has risen, turn it out onto a lightly floured surface and divide it into 6 equal portions.
Shape each into a ball and place on a parchment lined baking sheet.
Let rise while you prepare the topping.
Combine all topping ingredients in a bowl and mix very well. Let stand for 15 minutes.
Once the rolls have risen a bit, and the topping is ready, spread a generous layer on each roll, trying to use all the topping in a thick coat on the top and sides of the ball.
Start preheating your oven to 375º F.
Let the dough balls rise for another 20 minutes.
Bake for 25-30 minutes, until well browned. Let cool completely before eating.
