S’mores Blondies
Please watch marshmallows when you broil them as they will toast very quickly.
The blondies can be a little tough to cut due to the stickiness of the marshmallows— my tip is to lightly spray your knife with nonstick spray before cutting for cleaner slices.
You can prep the bars a day in advance and then broil them the day you want to serve them. Store baked bars at room temperature with the lid, or in an airtight container.
