Preheat oven to 425°F. Line a large sheet pan with parchment paper and set aside.

In a large bowl, combine one cup of flour, yeast, sugar, salt, water, and oil. Stir to combine. Add more flour until the dough is slightly sticky but forms a ball.

Place dough on a floured surface and knead for 4 minutes until smooth and elastic.

Divide dough into 4 equal portions. Pat or roll each into a 4-inch circle for the large base, 3-inch for the torso, and 2-inch for the head. Arrange to resemble snowmen with overlapping circles.

Pinch edges of each circle to form small edges to hold sauce.

Spread Alfredo sauce onto each piece of dough.

Decorate snowmen with black olives for eyes and buttons, pepperoni for scarves, and yellow bell pepper for noses.

Bake for 15 minutes until crust is golden and cheese is melted.

Sprinkle with Parmesan cheese and serve warm.
