Preheat your oven to 400°F (200°C) and lightly grease a muffin tin.
Roll out the pizza dough and slice into six long horizontal strips.
Spread a light layer of marinara sauce on each dough strip.
Place mozzarella cheese slices on top of the sauce.
Line each strip with pepperoni slices, allowing half of each slice to hang over the dough edge.
Carefully roll up each strip to form a rose shape.
Place each rose in the greased muffin tin cups.
Bake in the preheated oven for 15 minutes until golden and bubbly.
Remove from the oven and let cool slightly before serving.
