Prepare the filling mixture by combining the softened cream cheese with the jalapenos, bacon, shredded cheese, salt + pepper and garlic powder.
Divide the mixture among the tortillas and spread it out in an even layer edge to edge and roll them up. Slice into 2" wide pieces (discarding the end pieces if desired).
Heat butter in a skillet over medium low. Add the pinwheels cut side down and toast about 2-3 minutes or until golden brown. Flip and repeat. Optionally, toast the sides for 1 minute. Serve warm.
