I know that peanut butter and chocolate is the best together, but I am a complete peanut butter fan. You know the chocolate and peanut butter Buckeye candy? My favorite part of the Buckeye is the peanut butter. I eat peanut butter with apples, pretzels, and crackers of any kind. My dog, Josie, is the same way. Keep an eye on her when peanut butter is around.  She tries to get her paws on it any way she can.  Unfortunately for her, she doesn’t get to eat as much as she’d like.

Although I love homemade cookies, there is a store-bought cookie that I can’t resist. Can you guess what it is?

Nutter Butters.  I mean, really. There’s not much better than a cold glass of milk and a pile of Nutter Butters.Nutter Butter Peanut Butter Cake - Tastes of Lizzy T

Last weekend, I was cake deprived. After I made the Reese’s Peanut Butter Cake,  it seemed useless to try and beat it. Then I had an idea. What would be better than to make just a plain peanut butter cake and decorate it with my favorite Nutter Butter cookies? Using the awesome peanut butter icing recipe, I made this delicious monster of a cake.

Before I made this Nutter Butter Peanut Butter Cake, I looked up on the computer for a good from-scratch recipe for peanut butter cake. I found one that looked good, but when I made it, I realized it just wasn’t the cake I was looking for.  But how can you just throw away a homemade cake? This is the best kind of failure: Stuck at home with a peanut butter cake that is up for grabs!

I ended up using a yellow boxed cake mix and altered it using the Peanut Butter Silk Cake recipe found at Betty Crocker. I love making cake from scratch, but I also love doctoring up a boxed cake mix.  So easy!

My adventure that started with a disaster ended with a wonderfully simple cake all based on my favorite food: peanut butter.
