I have never made whoopies before (or eaten any as far as I know) and the recipes look easy enough to follow. So this morning I browsed through - looking for the perfect recipe (the one I had ingredients for in my pantry)
And there it was on pg 62 : chocolate brownie whoopies
They are VERY VERY good, crispy and chewy at the same time. Just like a real brownie.
My only adjustment was in the filling, I didn't have cream cheese, so I used my regular butter icing recipe instead.
The recipe only makes 8 whoopies. But the first picture shows them on a dinner plate so you can see they are quite large.
