Preheat over to 350*F.

In a large bowl, mix flour, baking powder and cocoa powder.

Using a hand mixer, cream together butter, brown sugar and sugar. Add 1/2 tsp of salt.

Once creamy, add in peanut butter, egg, heavy cream and vanilla extract. Beat until fluffy.

Slowly add in flour mixture until well incorporated.

Roll 1-in dough balls and place on a baking sheet lined with parchment paper.

Place in oven for 2 minutes. (Remove after 2 minutes and flatten cookies with a fork, making a criss-cross pattern. Allowing the cooking a few moments to cook will keep them from cracking).

Return cookies to the oven and bake for 8-10 minutes or until golden brown.

Allow cookies time to cool on baking sheet (10 minutes), then transfer to a cooling rack.
