Preheat oven to 350 degrees.

Spray an 8 or 9-inch pan with butter flavored cooking spray.
Tip: Line the pan first with foil and spray. This trick makes clean up easier.

Pour the sugars and sake into a saucepan. Add cubes of butter. Over medium-low heat, combine the sugars, sake and butter. To avoid burning the mix – keep stirring. Once the mixture is boiling, take the saucepan off the stove.

Sprinkle in the chocolate chips and stir vigorously. Once the chocolate is incorporated, pour in the teaspoon of vanilla. Add the eggs.

Stir in the flours, baking powder and salt. Combine well. Sprinkle in the sesame seeds and stir again.

Pour the batter into the prepared pan. Smooth the top with an offset spatula. (The kind used for frosting.)

Bake for 25 minutes or until a toothpick inserted in the center comes out clean.

Eat plain or drizzle melted white chocolate on top. Either way the brownie is scrumptious!
