Place the peanut butter, butter, sugar, maple syrup, chocolate chips and nutmeg in a saucepan. Heat over low heat until smooth and melted, stirring constantly. Remove from the heat and stir in the vanilla extract.
Place the corn flakes and Sesame seeds in a large bowl.
Pour the peanut butter mixture over the corn flakes and seeds; mix well (crush the corn flakes while combining with the mixture).
Lightly spray an 11x8-inch baking dish with cooking spray. Spoon evenly the corn flakes mixture into the dish, pressing down to flatten the top.
Chill until firm, about 4-5 hours. Then cut into squares.
Store them covered in the fridge.
