How to Store and Freeze

  • Store the blondies at room temperature in an airtight container for up to 3 days.
  • If you plan to freeze a whole pan of blondies, line the pan with a length of parchment paper, leaving some overhang. When cool, remove the brownie slab from the pan. Wrap the slab in plastic wrap and then wrap in foil. Freeze for up to 3 months.
  • To freeze individual blondies, layer them in a container divided by sheets of parchment paper. Cover the top layer of blondies with parchment as well. Seal the container and freeze them for up to 3 months.
  • Bring frozen blondies (whole slab or individual squares) to room temperature on the counter before serving.

Why Are They Called Blondies?

The rich, buttery brown sugar bars are similar in texture to chocolate brownies, but the color is blonde, hence the name blondies or blonde brownies. Blondies frequently include chocolate chips or chunks and chopped nuts.

Should Blondies Be Gooey?

Blondies should not be overbaked, but you don't want to underbake them either. Remove blondies from the oven when the center is still light and somewhat soft and the edges are browned. Blondies should be moist in the center. The blondies will firm up when cooled.
