My only variations from the original recipe:
1.) Individual servings: I wondered how this recipe would hold up if there were made into individual cakes (I worry that the cake would come out too dry). For the individual servings I used 6 flat bottom baking cups (they look like mini panetone liners), and adjusted the baking time (325F for ~25 minutes):
2.) Pecans: I usually go for the toasted chopped pecans instead of the peanuts. I prefer the taste and texture of pecans: 3.) Caramel sauce recipe quantity: As the caramel sauce recipe makes WAY more that you would need for a single cake, I cut that recipe in half.
I loved these little cakes!!! The cake itself was very moist (whew!), and they were a perfectly sized individual portions. This caramel sauce is wonderfully gooey and it makes for a terrific presentation if you pour the sauce over the cake as you serve it to your guests. The bonus on the the caramel --- it doesn't turn to a hard brittle when it cools.
