Brown Butter Rice Krispie Squares 

Fall is just starting to poke its head out, which means it’s the official start of baking season! Don’t get me wrong, I bake all year round, but during the fall months I really kick it into high gear. This past weekend my four-year-old and I decided to make these treats and they turned out great. The secret ingredient is brown butter!

What is brown butter?

Brown butter will change your life. Brown butter adds a deeper, more nutty flavour to the butter which totally enhances your baking. Making brown butter is really easy. All you need is to put your butter in a saucepan over medium heat. Allow the butter to melt and begin to froth and bubble. After about 5-8 minutes you will notice the butter turning from a light yellow to a rich brown. This is the milk solids inside the butter browning. You will smell the amazing aroma! Once you see the butter is brown, remove from the heat. Boom! You just made brown butter! Well done, Chef!
