Here's how to make them!
Ingredients:
Directions: Preheat oven to 350 degrees Fahrenheit. In a stand mixer, cream butter sugars. Add the eggs. Mix the flour, baking soda, and oats, then slowly combine with egg mixture. Spread ¾ of the oat dough into a 9-inch-by-13-inch rectangular baking pan, using a spoon to spread to the edges.
In a pot on medium-low heat, melt together the sweetened condensed milk, chocolate chips, butter, and vanilla. Pour and spread this over the layer of oat dough. Top with the remaining oats, dropping in clumps over the chocolate. Bake for 25 minutes, then cool and freeze before cutting into squares.
