Notes

1. Use jimmies style sprinkles for best color hold; Avoid overmixing after adding flour to keep blondies chewy; For thicker bars use an 8 inch pan and bake toward the longer end of the range; Swap white chips for chopped white chocolate or omit; Store airtight up to 4 days or freeze sliced bars up to 2 months
