Peanut Butter Cup – Add a layer of chocolate ganache or frosting, add chocolate chips to the cake mix, drizzle chocolate over the top. Crush up peanut butter cups and sprinkle across the top.

Nut Topping – From peanuts to pecans, or anything in between – crush up nuts and sprinkle across the top of the cake.

  1. Love this idea & love the peanut butter cake recipe! Thank you for sharing. I hope I did the linky correct. It was my first time!

  2. Looks amazing can you send me a piece? My daughter refuses to eat anything with peanut butter in it so if I made it I would for sure it the whole thing myself.

    1. I can definitely try to send you a piece, but you don’t want to eat this whole cake yourself (even though it is terribly tempting). LOL It’s actually super filling so I had to cut my kids the thinnest slices or they were moaning on the couch 20 minutes later… “Oh I ate too much.” So funny, but it’s true. Super amazing and delicious you don’t WANT to stop eating!

    1. Tina I am so thrilled to be a co-host with the rest of you amazing, talented foodies. You’re awesome, I love everything you do and I’m really excited for 2012. Like, really excited. 🙂 I get to see you! Right here, in my hometown. I’m giddy!

  3. When you send Sara her piece, include like half the cake for me too, ok? Seriously, girl, peanut butter? The one thing I would take with me to that deserted island…

  4. Looks absolutely wonderful, Nicole! I have always been to scared to cook a fancy two layer cake. That and my family never eats the sweets I make so they end up at the office! Peanut butter desserts are our favorite, though!

  5. Thank you so much for posting an all peanut butter cake. My husband is allergic to chocolate but loves PB and most PB cakes/desserts all have a chocolate ingredient. I’m excited to have him try this!
