If you love brown butter rice krispie treats, but are looking for something with a bit more flavor then it’s time to make these scotcheroos! A delicious blend of brown butter, melted gooey marshmallows, rice cereal and melted butterscotch. Plus a rich topping of peanut butter chocolate ganache, for the ultimate rice krispie treat experience.

Butterscotch Rice Krispie Treats
Scotcheroos are a basically a rice krispie treat recipe made with butterscotch, peanut butter, and chocolate. A simple, but rich dessert created in the 1960’s and printed on the Rice Krispie boxes sold in stores. A childhood favorite that never gets old!
This recipe has the perfect ratio of extra melted marshmallows to cereal for a gooey, chewy not dry scotcheroo. And with the addition of brown butter, there’s a toasted nuttiness that just brings it all together.
Browning the Butter
Brown butter is made by cooking unsalted butter until the milk solids turn a medium brown color. This process cooks out any of the water in the butter resulting in a rich nutty or toasty flavor. A great technique for adding more depth to your baked goods.
To make brown butter, beurre noisette in French, simply place your butter in a light colored skillet so you can see the color change and cook on medium heat. First the butter will start to foam as it melts, then it will slowly change from a golden hue to a darker more toasty brown color. It should start to give off a nutty aroma as it browns. It’s important to continue to stir the butter as it cooks to evenly toast and distribute the browning milk solids.

Peanut Butter Chocolate Ganache
Don’t even think about having a Scotcheroo without a thick layer of peanut butter ganache! The trick to not making this simple dessert too rich, is the choice of chocolate.
I prefer to use a semi-sweet chocolate with 50-60 % Cocoa. This seems to be the sweet spot for a perfectly blended ganache to balance the butterscotch and marshmallows.

Leftovers and Storage
Room Temp: After the ganache has set, I slice my chocolate rice krispie treats into squares. Place the squares in an air tight container layered with parchment paper. If you need to stack them, place some parchment paper or wax paper between the treats. Store at room temperature for 3-4 days for maximum freshness.
Freezing: Place the scotcheroos in a freezer safe container for up to 3 months. Thaw at room temperature for 2 hours before cutting and serving.
