These oatmeal cream pie cookies are incredibly chewy with a hint of cinnamon, brown sugar and vanilla. The filling is deliciously creamy and not too sweet either. They're the homemade version of the classic Lil' Debbie cookies, but so much better!
Preheat the oven to 350F (180C or 170C fan forced). Line cookie sheets with silicone baking mats or baking paper.
In a large bowl, beat the butter until fluffy.
Take 1 cooled cookie and frost the bottom with about 1 to 1.5 tablespoons of frosting.
