This is like a homemade ice cream cake. From Odessa Simpson’s collection.
1/2 gallon vanilla ice cream, softened
1/2 C brown sugar
2 C flour
2 sticks of butter (1/2 lb), melted
1/2 C oatmeal
1/2 t salt
1 C chopped pecans
Combine all ingredients except ice cream, mix like cookie dough. Spread on large cookie sheet and bake 15 minutes at 400 F. Crumble with a fork while still hot. Spread half of the crumbs in large baking dish (9×12). Drizzle half a 12-oz jar of butterscotch or caramel over the crumbs. Spread ice cream over this and then the rest of the crumbs. Drizzle the remaining caramel over the top. Freeze several hours. Take out 10 minutes before serving.
