Before You Bake

Do I need to toast the pecans first?
Toasting isn’t required, but it does bring out a deeper nutty flavor. If you have a few extra minutes, spread them on a baking sheet and toast at 350°F for about 5 minutes.

When should I add the royal icing decorations?
If you want them slightly baked in, press them gently into the batter before baking. 

Can I make these ahead of time?
Yes! These blondies keep well at room temperature for 2–3 days in an airtight container. They can also be frozen (without the glaze) for up to a month.

FAQ

How do I cut blondies cleanly?
Wait until they’re fully cooled, then use a sharp knife wiped clean between slices.

Can I double the recipe?
Yes, just use a 9×13-inch pan and adjust the baking time slightly. Check a few minutes early to avoid overbaking.

Can I swap the nuts?
Absolutely — walnuts, almonds, or even pumpkin seeds work if pecans aren’t your thing.

What’s the best way to store glazed blondies?
Keep them covered at room temperature. If your kitchen is warm, store in the fridge and let them come to room temp before serving.

Are these blondies chewy or cakey?
They’re soft and chewy thanks to the maple brown sugar mix and the toffee pieces that melt into the batter.

Sprinkle of Fun

Serve up your Autumn Crunch Blondies around a backyard fire pit with mugs of warm apple cider. Pass the bars on a platter while everyone takes turns sharing their favorite fall memories or telling spooky (but fun!) stories. It’s the kind of low-key hangout that makes the blondies feel like part of the tradition.
