Warm milk to 110°F-115°F then whisk in sugar in the bowl of your stand mixer until dissolved
Sprinkle yeast over the top of milk mixture, cover the bowl with a kitchen towel and let stand in a warm spot for 10-15 minutes until yeast is frothy
Add butter, egg, salt and flour then knead in the bowl of your stand mixer fitted with the dough hook attachment on low speed for 3 minutes
The dough should have formed a ball, be soft but not too sticky. If it's too sticky add a little flour
Place the dough in a lightly greased bowl, cover it with a kitchen towel and let rise in a warm spot for 60-90 minutes
Once the dough has risen, turn it out onto a lightly floured surface and punch the dough down once to get the air out
Divide the dough into 4 equal parts and roll them into balls
Roll 1 section of dough into a 10-12 circle and place it on a baking sheet lined with parchment paper
Spread ⅓ of the pesto, artichoke and cheese over the dough. Roll out the next ball of dough, layer it on top of the first and repeat this process until all the dough is layered on top of each other. Do not put filling on top of the last layer of dough
Using a pizza cutter, trim the outer edges of the circle to for a round shape
Place the 3 inch diameter object directly in the center of the dough and press down firmly but do not press all the way through
Using a pizza cutter cut the dough in half directly down the center one way then directly down the center in the opposite direction being careful NOT TO CUT THROUGH THE CENTER WHERE THE 3 INCH DIAMETER IS. Leave the center circle intact the entire time
You should have 4 equal sections of dough. Cut each of those in half to have 8 sections of dough. Cut each of those in half to end up with 16 strips of dough
Grab 2 strips of dough next to each other, slightly lift them then twist outwards 3 times and press the ends together to form a point
Repeat with remaining dough strips
