Preheat oven to 350 degrees Fahrenheit. Line or grease a 9×13-inch baking pan. NOTE: You can mix all the ingredients in the same bowl you use to melt the butter if you’re using a large-enough bowl.

In a bowl, combine butter, oil and brown sugar. Mix to combine. Add eggs and vanilla and mix. Add flour and salt and mix until combined. Fold in white chocolate.

Meanwhile, add pretzels to a Ziploc bag and give them a few good bangs with a mallet, the bottom of a pot, or anything you have in the kitchen that’s nice and strong. You should end up with a variety of sizes of pretzel crumbs and pretzel pieces. Fold pretzels into batter.

Add batter to prepared baking pan. Bake for 30 minutes. (Note: In my oven, 30 minutes was perfect in a disposable. It would be shorter in a Pyrex…plus all ovens are different.)
