Line a 9x13" pan with parchment paper so it hangs over the edges. Preheat the oven to 350 degrees Fahrenheit.
Place all ingredients, except white chocolate chips, in the bowl of an electric mixer and mix until combined, scraping down the sides as you go. Quickly mix in white chocolate chips.
Press/spread dough into prepare pan, press additional white chocolate chips on the top (if desired) and bake for approximately 18-20 minutes or just until set. Allow it to cool completely on a cooling rack, then use the parchment paper to carefully lift it from the pan. Slice into bars and enjoy.
