1-First, preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper for easy cleanup, which helps keep things neat for busy parents or students multitasking in the kitchen.

2-Next, in a large bowl, cream together the softened butter and brown sugar until light and fluffy, giving that base a rich, irresistible flavor. Then, beat in the egg and vanilla extract, adjusting to vegan options if needed, to bind everything together nicely. In a separate bowl, whisk together the rolled oats, all-purpose flour (or gluten-free alternative), baking soda, and salt, ensuring even distribution for that signature chewy texture.

3-Gradually incorporate the dry ingredients into the wet mixture, mixing until well combined, and don’t forget to add the cinnamon for a warm spice that makes these pies extra special. Scoop tablespoon-sized portions onto the prepared baking sheet, spacing them evenly to allow for spreading during baking. Bake for 10-12 minutes or until edges turn golden brown, then allow the cookies to cool completely on a wire rack before assembling to keep them from getting soggy.

4-once cooled, prepare the cream filling by mixing the softened butter, powdered sugar, and vanilla extract until smooth, and stir in the milk or half and half for the right consistency. Spread the filling on the flat side of one cookie and sandwich with another, then chill the assembled oatmeal cream pies in the refrigerator for 30 minutes before serving to set the filling.
