01 - Combine cream cheese, shredded cheddar, Monterey Jack, garlic powder, smoked paprika, and salt in a mixing bowl. Beat until completely smooth and evenly blended.
02 - Gently fold chopped jalapeños and sliced green onions into the cheese mixture until uniformly distributed throughout.
03 - Layout flour tortillas on a clean surface. Spread an even layer of filling over each tortilla, maintaining a 1/2-inch border around edges to prevent overflow during rolling.
04 - Roll each tortilla tightly into a compact cylinder. Refrigerate for 10 minutes to firm the filling for cleaner slicing.
05 - Heat oven to 375°F and line a baking sheet with parchment paper.
06 - Cut each chilled roll into 1-inch thick rounds. Arrange pinwheels cut side up on prepared baking sheet, spacing 1/2 inch apart.
07 - Lightly brush tops of pinwheels with melted butter using a pastry brush for even coverage.
08 - Bake for 12–15 minutes until tops are golden brown and filling is bubbling. Watch closely to prevent over-browning.
09 - Remove from oven and let cool for 5 minutes. Sprinkle with fresh cilantro if using. Serve warm or at room temperature.
