Want to take a quick trip back to your childhood? We grew up eating this Crumbled Butter Brickle Ice Cream Dessert at Grandma's house. A crunchy crumble topping, butterscotch, and vanilla ice cream come together to create a wonderful summer time treat.
In a large mixing bowl, prepare the crumble topping by combining the flour, oats, brown sugar, pecans and almonds; stir in the melted butter and mix thoroughly; spread the prepared mixture evenly over a baking sheet and bake for 15-20 minutes, stirring halfway through the baking time. Remove from the oven and cool completely.
To assemble the dessert, spread half of the baked and cooled crumble topping over the bottom of a 9 x 13 pan; drizzle with half of the butterscotch sauce.
Remove the softened ice cream from the container, cutting it into fat slices, placing them on top of the butterscotch topping in the 9 x 13 pan. (You may need to cut a few of the slices to fit, filling the pan.) Or, if the ice cream is super soft, you can just drop it by the spoonful over the crumble topping, gently spreading it together and towards the edges of the pan.
Sprinkle the remaining crumble topping over the ice cream slices, then drizzle with the remaining half of the butterscotch sauce. Place the dessert into the freezer until partially frozen, then cover with foil or plastic wrap and continue to freezer for 6-8 hours before serving. Let dessert soften a bit before you cut it into squares to serve.
