Preheat the oven to 325º
To make blondie cake, whip the egg whites until they are stiff and form peaks.
Add softened butter, ½ c packed brown sugar, ¼ c granulated sugar, and vanilla and mix with an electric mixer until smooth.
In a separate bowl sift together flour, baking soda, baking powder and ¼ tsp salt.
Add the dry ingredients to the wet ingredients and mix well until smooth. Mix in milk, white chocolate chunks, and walnuts.
Pour ingredients into a greased 9×13 inch baking pan and bake for 40 to 45 min. or until the cake is golden brown on top.
Slice the cake into 8 equal slices when cool.
While cake bakes, combine all ingredients for the sauce in a medium bowl with an electric mixer.
To prepare dessert, heat a small skillet on your stove over high heat for about 5 minutes. A cast-iron skillet is the best. Arrange the cake in the center of skillet or plate.
Heat up the sauce for 30-60 seconds in the microwave until hot. Place a scoop of vanilla ice cream on the cake, then drizzle some of the sauce over the top, followed by a Tablespoon of chopped walnuts.
Serve immediately. (serves about 8)
