1) Preheat the oven to 325 ⁰ F.
2) In a large bowl, stir the flour and powdered sugar together.
3) Add the softened butter and vanilla and mix with a hand mixer until fully blended. The dough will be crumbly, but when you mix it with your hands, it will form together.
4) Place a piece of parchment paper with some sprinkled flour and form dough into a ball.
5) Roll the dough until it's about 1/2 inch thick and cut into desired shapes. (I used a heart shaped cookie cutter
6) Bake in the oven for 12-15 minutes, until the bottom is just slightly golden.
7) Let cool for 10 minutes and transfer to a cooling rack.
8) In the meantime, melt your chocolate on the stovetop in a small saucepan, stirring occasionally so it doesn't stick. Alternatively, microwave in 30 second increments. Mix in the peanut butter.
9) When cookies are cooled, dip them in the peanut butter chocolate.
