In a medium-size bowl, prepare the pretzel dough according to the directions on the box.

Allow the dough to rise 25 minutes as directed.

Preheat the oven to 400 degrees.

Put a pot of water (about 3 quarts) on the stove to boil.

Split the dough in two pieces.

On a lightly greased or non-stick surface, roll each piece of dough into a snake about 1-1 1/2" in diameter. Using a knife or pizza cutter, cut the snack into 1-1 1/2" pieces, making about 15 pieces of dough.

Flatten each dough ball with the palm of your hand until it is about 1/4" thick.

Spoon the Nutella into a disposable frosting bag or Ziploc bag. Cut about 1/2" of the tip of one the bag (or one of the corners of the Ziploc bag).

Squeeze a dollop of Nutella into the center of each flattened piece of dough, The Nutella dollop should be about the size of a quarter.

Fold each dough ball together, completely covering and enclosing the Nutella. Roll it into a ball and pinch any seams closed.

Place each dough ball in the boiling water for 10 seconds, then remove them and place them on greased baking sheet.

Bake at 400 degrees for 12 minutes, or until golden brown.

Melt 1 stick of butter in a small dish.

Place the 1 cup of sugar in a separate small dish.

Once the pretzel doughnuts are cool enough to touch, dip each ball in the butter and turn to coat it, then place it immediately in the bowl of sugar and turn to coat.

These are best served warm, but are good later, too!
