- 1/2 cup (135g) smooth peanut butter
- 1 cup (125g) powdered sugar
- 2–4 tbsp milk or cream
- Preheat oven to 325F. Line 2 baking sheets with parchment paper or silicone baking mat.
- In a large bowl, toss together the quick oats, flour, baking soda and cinnamon. Set aside.
- In a medium bowl, whisk together the melted butter, brown sugar, eggs, maple syrup and vanilla.
- Add the wet into the dry ingredients and mix together until just combined. Fold in the diced apples.
- Using a medium cookie scoop or tablespoons, drop rounded cookie batter about 2″ apart onto prepared baking sheet.
- Bake for 10-12 minutes or until the edges are golden brown. Let cookies cool completely before filling.
To make the filling:
- Using an electric mixer, combine the peanut butter and powdered sugar. Add the milk or cream, 1 tablespoon at a time until you have a spreadable consistency.
The cookies are best enjoyed the day of. Due to the natural juices from the apples, the cookies tend to get moist the day after.
