01 - Combine softened cream cheese, shredded cheddar, Monterey Jack, garlic powder, smoked paprika, and salt in a mixing bowl. Beat until completely smooth and creamy, ensuring no lumps remain.
02 - Fold in chopped jalapeños and sliced green onions until evenly incorporated throughout the cheese mixture.
03 - Lay out each flour tortilla on a flat surface. Spread a generous layer of the cheese mixture over the entire surface, leaving a 1/2-inch border around the edges.
04 - Starting from one edge, roll each tortilla tightly into a compact cylinder. Refrigerate for 10 minutes to firm up 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 pinwheels using a sharp knife. Arrange pinwheels cut side up on the prepared baking sheet, leaving slight space between each.
07 - Lightly brush the tops of each pinwheel with melted butter. Bake for 12-15 minutes until golden brown and the cheese filling is bubbly and heated through.
08 - Remove from oven and let cool for 2-3 minutes on the baking sheet. Garnish with fresh chopped cilantro if desired. Serve warm or at room temperature.
