01 - Combine cream cheese, cheddar, Monterey Jack, garlic powder, smoked paprika, and salt in a mixing bowl. Mix until completely smooth and well-blended.
02 - Fold in the chopped jalapeños and green onions until evenly distributed throughout the cheese mixture.
03 - Lay out flour tortillas and spread a layer of the filling over each, leaving a 1/2-inch border around the edges.
04 - Tightly roll up each tortilla and refrigerate for 10 minutes to firm up the filling for easier slicing.
05 - Preheat oven to 375°F.
06 - Cut each chilled roll into 1-inch pinwheels and arrange cut side up on a parchment-lined baking sheet.
07 - Lightly brush the tops of each pinwheel with melted butter for golden browning.
08 - Bake for 12 to 15 minutes until golden brown and heated through.
09 - Remove from oven, cool slightly, and garnish with chopped cilantro if desired. Serve warm or at room temperature.
