01 - Combine cream cheese and sour cream in a medium bowl. Beat until completely smooth and creamy.
02 - Add cheddar cheese, red bell pepper, green onions, black olives, garlic powder, salt, and black pepper. Stir until all ingredients are evenly distributed.
03 - Place a tortilla on a clean work surface. Spread one-quarter of the filling mixture evenly across the entire surface, extending to the edges.
04 - Roll the tortilla tightly from one end to the other, creating a compact cylinder. Repeat with remaining tortillas and filling.
05 - Wrap each rolled tortilla individually in plastic wrap. Refrigerate for at least 1 hour to firm up for clean slicing.
06 - Remove plastic wrap and slice each roll into 6 equal pinwheels. Arrange on a serving platter and serve immediately.
