Storage/Reheating

Store blondies in an airtight container at room temperature for up to 4 days. For longer storage, refrigerate for up to 1 week or freeze for up to 2 months. Thaw at room temperature before serving. If you prefer them slightly warm, microwave individual blondies for 10–15 seconds.

FAQs

Can I use nonpareils instead of jimmies?

It’s not recommended. Nonpareils tend to bleed color into the batter. Jimmies hold their shape better when baked.

How do I know when they’re done?

The edges should be golden, and the center should look set. A toothpick should come out with moist crumbs, not raw batter.

Can I double the recipe?

Yes, double the ingredients and use a 9×13-inch pan. Adjust the baking time to about 35–40 minutes.

Do they need frosting?

Not at all! They’re flavorful on their own, but you can add frosting if you want extra sweetness or decoration.

Can I add nuts?

Yes, chopped walnuts or pecans add a nice crunch and balance the sweetness.

What makes blondies different from brownies?

Blondies are vanilla-based and made with brown sugar, while brownies are chocolate-based.

Can I use oil instead of butter?

Butter provides the best flavor, but you can substitute an equal amount of vegetable oil in a pinch.

Should I chill the dough?

No chilling is necessary—this is a quick and easy one-bowl recipe.

What kind of pan should I use?

An 8×8-inch metal or glass baking dish works well. Metal tends to give crispier edges.

Can I make these egg-free?

Yes, use a store-bought egg replacer or try flax eggs, though texture may vary slightly.
