When I was in high school, I worked for an Irish family...and they made these yummy treats each year for St. Patrick's Day. The sweet frosting and salty peanuts are an irresistible combination. The only complaint my husband has is that I make them just once a year! -Bridget Jones, Veyo, Utah

"I could only give this recipe a 1 star. Like a previous review stated, the cake fell in the middle. I bake a lot so I am not an amateur and I would say to move on and find a cake that is a little lighter and not so eggy."

"We were disappointed as the cake was too heavy and the frosting just not right. I was looking for something like I sometimes find in a bakery with an airy white cake and fluffy frosting."

"Grew up with these as a bake sale staple in my Dad's home town in MO. Today is his 81st BD, and I thought it would be fun to surprise him with a batch of these.

Followed the directions exactly and the end result was perfection! It makes sense to freeze the cake overnight as it is much easier to work with and the icing and peanuts adhere much better.
Definitely a keeper, and something to be passed down."

"I know its cheating but I just use white cake mix when making, for those having trouble with falling cake."

"I had made theses several years ago for st Patricks day and they were good. I wasn't 100% thrilled with the frosting and will try the suggestions to add some softened butter. To itsnotdew. Cakes usually fall in the center due to insufficient mixing of batter. It's happened to me also. I remember one time after mixing pouring the batter in the pan and you could tell it was not fully mixed and it fell in the center. Try mixing thoroughly good luck !"

"I have made these for the last 2 years. The cakes fell in the center last year. My oven was bad, temperture all messed up, so I figured that was why. I forgot to make a note of it on the recipe. Today, I made 2 more cakes, & the center fell on both of them. And I have a brand new stove, so it can't be that. I am so surprised no one else has said theirs fell too. The cake is really good, so I gave it 3 stars, but I sure don't like flat cakes in the whole center. Not even enough cake around the edges to cut out pieces. I will still frost & nut the cake, but the pieces will only be half as high. The recipe calls for 3 teas of baking powder,could that be too much? Does anyone know why cakes fall?"

"I liked the taste a lot, but they were a little difficult to put together. I think the frosting needs to be a little thinner to adhere to the frozen cakes. Will definitely make these again, though"
