01 - In a mixing bowl, combine cream cheese, cheddar, Monterey Jack, garlic powder, smoked paprika, and salt. Mix until smooth and well-blended.
02 - Fold in the chopped jalapeños and green onions until evenly distributed throughout the cheese mixture.
03 - Lay out the flour tortillas and spread a layer of the mixture over each, leaving a 1/2-inch border around the edges.
04 - Tightly roll up each tortilla into a log. Chill for 10 minutes to firm up for easier slicing, if time permits.
05 - Preheat oven to 375°F.
06 - Slice each roll into 1-inch pinwheels and place them cut side up on a baking sheet lined with parchment paper.
07 - Brush the tops lightly with melted butter using a pastry brush.
08 - Bake for 12 to 15 minutes, or 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.
