In a medium bowl, combine flour, baking soda, baking powder and salt. Set aside.
In the bowl of an electric mixer, beat shortening, butter, both sugars and peanut butter until smooth.
Continue beating and add egg and vanilla extract.
Add dry ingredients to wet ingredients and beat at low speed until well combined.
Stir in oats.
Scoop the dough onto cookie sheets using a small cookie scoop, placing about 2” apart. Do not press down as they will flatten slightly as they bake.
Bake for 13-15 minutes or until set and slightly browned around the edges.
Let cool on cookie sheet for 3 minutes then remove to wire rack to cool completely.
Once cool, pair cookies together with like size. Spread a bit of strawberry jam, or your family’s favorite jam, on to one of the cookies. Place another cookie on top to create the perfect peanut butter & jelly treat.
Only make as many sandwich cookies as you will need right away as the cookies tend to soften when sitting with the jam on them. By the way, they’re also terrific eaten all by themselves!
