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 chopped jalapeños and green onions until evenly distributed throughout the cheese mixture.
03 - Lay out flour tortillas on a clean surface. Spread a layer of the cheese mixture over each tortilla, leaving a 1/2-inch border around edges.
04 - Tightly roll up each tortilla into a compact cylinder. Chill 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. Place cut side up on a baking sheet lined with parchment paper, spacing evenly.
07 - Lightly brush the tops of each pinwheel with melted butter using a pastry brush.
08 - Bake for 12–15 minutes until golden brown and heated through.
09 - Remove from oven and cool slightly. Garnish with chopped cilantro if desired. Serve warm or at room temperature.
