First cut each cookie into 4 pieces. Grab 3 or 3 cookies and just snap them in half with your fingers and snap each half again. Place into a bowl. Snap the freeze dried mango in half and place that in a bowl. You can place it in the same bowl as the cookie pieces.
In a large pot dump in the bag of marshmallows, 1 stick of butter, ¼ of Ube Halayaand 2 Tablespoons of Ube Cookie Butter. Turn the heat to medium and wait for the marshmallow and butter to melt. Keep mixing so that nothing sticks to the bottom of the pan. After about 2 minutes everything should be melted. Turn down the heat to your lowest setting. Add in the milk powder. Mix well until it's fully combined.
With the heat still on low so that the marshmallow mix stays soft, dump in all the cookies, dried mangoes and banana chips.
Mix until everything is coated in the Ube marshmallow mixture making sure the bottom of the pan has also been scrapped.
Transfer everything to a pan that has been lined with parchment paper.
Using the flat part of a spatula press down so that the top is as flat as you can get it.
Dust 2 tablespoons of milk powder all over the top. Then top with another piece of parchment paper and use something small and flat like a cutting board to flatten it some more.
Take off the parchment and small cutting board and place a large cutting board over the pan and invert the Ube Snowflake Crisp on the cutting board.
Dust more milk powder on the other side and cut into small squares. You can get between 30-60 squares depending on how big or small you cut them.
