Prepare pizza crust according to package directions. Divide dough into 8 portions.
On lightly floured work surface, roll out each portion into large round, about 1/4-inch (5 mm) thick.
Using large maple leaf cookie cutter, cut out 8 maple leaves, rerolling dough as needed. Transfer maple leaf pizzas to 2 large parchment paper–lined baking sheets, about 2 inches (5 cm) apart.
Top each pizza with pizza sauce and mozzarella. Garnish with pepperoni, bacon, sausages and mushrooms.
Bake according to package directions, about 12 to 16 minutes, or until crust is golden brown. Drizzle with maple syrup before serving (if using). Let cool for 5 minutes before serving.
