  1. This cake was fantastic and well worth taking the time to make it

    1. Thanks so much! It’s one of our favorites! So glad you enjoyed it also.

  2. This cake was the highlight of my Thanksgiving; much better than the company at my table

    1. lol so happy you enjoyed the cake! 🙂

  3. Made this cake ABSOLUTELY following all direction. Batter divided into 2 x 8inch round pans as directed. The batter overflowed the pans, making a complete mess in my oven. And at 25 minutes, the pans still “jiggled” like they were full of water. Disaster…was making for a family Easter dessert…of course

    1. Sorry this didn’t work out for you. As you can see from the video and pictures the cake is made in 2 8 in pans. we have never had a problem or issues with the cake not being cooked
      or done after 25-30 minutes but you could have cooked it longer until cooked.

  4. 5 stars
    This cake is so delicious. I have made this 3 times now and it is a big favorite. Making it tomorrow for Easter Sunday too. Pure decadents and a family favorite.

    1. So happy to hear that everyone loved this cake Jackie. It’s one of our favorites too. It never disappoints.

    1. Look at all these delicious Peanut Butter and Chocolate Desserts! Where do we start?

    Made this for my mother’s birthday. It was delicious! Not sure if it is an altitude difference, but I made this in 2- 9 inch cake pans and it was perfect.(8inch would have been too small.) I made it the night before and stored it in the fridge, but forgot to remove it as soon as I got up in the morning. It was good when it was still a bit chilled but out of this world at room temp!

  6. 5 stars
    Omg what a decadent luscious cake The peanut butter filling is so fluffy and creamy and the chocolate cake is dreamy and the ganache on top makes it out of this world My only issue was having flour mixture popping out of kitchen aide mixer Id give this a thousand stars if I could 💕💕

    1. So happy you love this cake. It is one of our favorites!

  7. 5 stars
    I keep trying to give you a five star rating I adored this luscious sinful decadent cake with fluffy peanut butter filling and moist chocolate cake with heavenly ganache No issue with using 8” pie pans I’m making it again! Thank you!💕

    1. Thank you so much Cindy! We are so happy you loved this recipe 🙂

  8. I made this as directed in 8” pans. I think it should have said 9”. It took so long to bake, at least 15 more minutes than the 25 in the recipe. Also it made for a very thick filling and more ganache than needed for an 8” cake!

    1. We always make this in an 8-inch pan. If you would like to try it in a 9-inch pan I’m sure it would be fine just a shorter cake and the time always works for us. We never bake more than 2 minutes. 40 minutes in a8 or 9 inch pan sounds much to long
