Let’s start by making the cookie dough! In a bowl mix together the butter, brown sugar, salt and vanilla extract. Add the milk and flour then mix again. Then mix in the chocolate chips.
We recommend waiting for the dough to come to room temperature before starting. Roll out your pizza dough on a floured surface to 1/8 inch thickness.
Cut 2-inch rounds using a cookie cutter or water glass. Remove excess dough, roll into a ball and repeat with the rest of the dough.
Spoon a heaping teaspoon of cookie dough into the center of each round. Fold up the ends and pinch at the top. Make sure all the sides are sealed well. Roll each ball to bring it back to an even shape.
Place each doughnut on a floured baking tray and let them rest for 15 minutes.
Fill a pot with vegetable oil and bring to 375℉. Carefully place a few doughnuts at a time into the oil. You can test the oil by adding a tiny ball of dough to the oil. It should bubble a bit, but not like crazy (yes, that’s a bit hard to explain if you don’t have a thermometer). Flip after 60-90 seconds and fry until browned on both sides.
Remove from oil and place on paper towels. Sprinkle with powdered sugar. Serve hot and fresh.
