To brown the butter: Place butter in saucepan over medium heat and bring to a boil.
Boil, stirring constantly until lightly browned.
This may take five or ten minutes.
Once butter has browned, place browned butter in a mixing bowl.
Add brown sugar and mix thoroughly with an electric mixer.
Allow mixture to cool about five minutes.
Meanwhile, place bananas on a plate and mash with a fork; set aside.
If the mixture still has not cooled sufficiently, wait a few more minutes before adding eggs, almond extract, mashed bananas and salt.
(So the egg doesn’t scramble!).
Mix again with electric mixer until thoroughly mixed.
Stir in flour, raspberries, vanilla chips and almonds.
Stir mixture until well combined.
Pour mixture into a greased 9x13” glass baking dish.
Bake at 350° for about 45-50 minutes until a toothpick inserted in center comes out clean.
Allow blondies to cool completely before icing with Almond icing.
