Fall is here! Fall is here! Fall is here!

And I can’t believe it, but I’m actually pretty excited. I’d been holding onto summer like something fierce, but I think I’m finally ready to embrace it all— changing leaves, chilly weather, and all things cinnamon.

Last weekend we took a drive up into the mountains to see if the leaves had turned yet, and they had! It made me so happy. You know something else that makes me happy? These white chocolate macadamia nut snickerdoodle cookie bars.

A few weeks ago I had a thought— white chocolate and macadamia nuts are a classic combination, and snickerdoodles and white chocolate go really well together, so why not combine it all into one?

I must be a genius, because these bars are brilliant! They’re soft, scented heavily with cinnamon, and packed with pockets of white chocolate and chunks of macadamia nuts. You’re going to fall in love with them just like I did.

Happy fall, everyone!

baking tip:Choosing the right white chocolate for melting

Look carefully at the labels of the “white chocolate” that you find in the baking aisle at the grocery store. While many bars and chips will be true white chocolate— consisting of cocoa butter, sugar, and milk solids— some are not. Synthetic white chocolate substitutes are made with palm oil or something similar and do not contain any cocoa butter. While they may be okay to use in baking, these substitutes will not melt well.

Make sure that what you buy is labeled as “white chocolate” and has “cocoa butter” listed in the ingredients. USDA regulations require that only true white chocolate can be labeled as such.
