Grease a muffin tin well with olive oil or line with cupcake liners. Set aside.
Roll out the dough
Roll your sourdough pizza dough into a large rectangle, about ¼ inch thick. Try to keep the thickness fairly even so the roses bake evenly.
Cut into strips
Use a pizza cutter to cut the dough into long strips, about 1½ inch wide. The length will depend on how big your rectangle is.
Add the fillings to each strip
Spread a thin layer of pizza sauce down the center of the strip. Don’t use too much or it will squeeze out while rolling.
Sprinkle shredded mozzarella over the sauce.
Lay pepperoni slices along the top edge of the strip, overlapping them slightly like shingles. Let about half of each pepperoni hang over the edge of the dough. This overhang is what creates the rose petal look.
Roll into a rose
Starting at one end, roll the strip up gently into a spiral. Keep it snug enough to hold its shape, but not so tight that the pepperoni can’t flare out at the top.
Place in the muffin tin and adjust
Set the rose into a muffin cup with the pepperoni side up. If any pepperoni petals are tucked in, gently fan them outward with your fingers so the top looks more like a rose.
Bake
Bake at 375°F for 20 to 25 minutes, or until the dough is cooked through and the tops are lightly golden brown.
Let them cool for 5 minutes in the pan before removing.
Notes
TipsUse a thin layer of sauce; too much can make the dough soggy or spill out while rolling.Roll gently but snugly; too tight and the dough won’t rise properly, too loose and the rose will fall apart.Serve warm for the best flavor.
