Preheat your 325°F (165°C) fan assist. Line 2 baking sheets with parchment paper and set aside.
In a small bowl, combine the flour, baking soda, baking powder and salt together until combined. Set aside.
Using a hand whisk, cream the butter and peanut butter together until soft, about 1 minute.
Mix in sugars and beat until light and fluffy, about 2 minutes.
Add in egg, milk, and vanilla and mix well until combined.
Lastly, stir in the dry ingredients and peanuts.
Scoop out a heaped tablespoon of dough, roll into a smooth ball, flatten into a 2-inch (5 cm) disc and arrange 3 inches (7 ½ cm) apart on the baking sheets.
Press your thumb into the center of each disc of dough and spoon a ½ teaspoon of jam into the divot.
Bake for 20-22 minutes, until the cookies are set the edges are beginning brown.
While the cookies are still hot, spoon an additional ½ teaspoon of jam onto the cookies. Let cool completely.
Store in an airtight container at room temperature for up to 2 days. These cookies are soft, and a little sticky so place parchment in between layers if stacking.
