Cover and run at high speed until all the ingredients are thoroughly blended and smooth.
Add about ¾ of the peanut butter and carob mixture to the flour mixture and mix thoroughly with a stiff spatula or spoon.
Gradually add a little more of the fudge mixture until desired consistency is reached.
If the cookie dough is too stiff, you may add more of the fudge mixture or water, if there is no fudge mixture remaining.
A thinner dough will make a flatter cookie.
A stiff dough will make irregular thick cookies like the ones shown in the photo (to test for dough stiffness, we stick a soup spoon upright into the dough. If the dough is stiff enough, the spoon will remain upright) on a non-stick or lightly oiled baking sheet, place the cookie dough in twelve equal sized "mounds" smooth and shape each cookie with a spoon or spatula, as desired.
Place the baking sheet in the preheated oven and bake at 350°F for 30 minutes.
Various ovens bake differently, so we suggest that you begin checking the cookies after 20 minutes of baking.
The cookies should be firm, but not hard.
Be careful not to over-bake.
When the peanut butter fudge cookies are baked, remove from the oven, cool, and enjoy.
