Thank you for the heads up. I would probably add some instant coffee granules to fortify the chocolate flavor in the chocolate in the mousse, and reduce the peanut butter to about 1 tsp.
We made these for my husband's BD. While they were good, the peanut butter completely overpowered the chocolate and it didn't really have a rich chocolate flavor. I would make these again, but I would omit the peanut butter and add a little more cream.
