Expert Tip

For best results, use a metal pan for this blondie recipe. Using a metal pan will allow the cookie bars to cook more evenly, keeping them soft and fudgy while allowing them to bake all the way.

FAQs

How do you know when blondies are done baking?

When the cookie loses its glossy sheen and is very light golden around the edges.

Why is using a metal pan important?

The metal pan is a heat conductor so it’ll help bake the cookie out evenly. 

Where can I find the Valentine’s day sprinkles?

At your local grocery store in the baking isle, look for baking decorations.

Can I freeze blondies for Valentine’s Day?

Yes you can! I usually freeze them in an airtight container up to 2 weeks in advanced. I love having this recipe ready to enjoy instantly on valentines day. These blondies can be frozen and remain fresh for up to 3 months.

  1. Hi, if I wanted to double this (would be great for Valentine’s treats for school) would a 13″ by 18″ sheet pan be big enough? If not what would you suggest or just make 2 batches?
