There is nothing lazy about this cake.  

No box cake mix is involved.  Nor, a tub of frosting.

The Lazy Daisy Peanut Butter Cake is considered a vintage cake.  

All made from scratch.

Long before cake mixes were even invented.

My great grandmother would make this cake for special occasions.  I specifically remember having this when I was so little.  Before kindergarten age.  

Sitting in the sun lit kitchen and eating a piece of cake with her, all awhile the other cousins were running around outside.  I some how felt very special sharing my piece of cake with her.

Now, I’ve been making this cake for my boys for the past 20 years… with a few of my own adjustments.

Eating this naked cake is just as good…

But, smothering it with the cooked brown sugar frosting is the best!

      Marcie, I love the taste of a homemade cake over any box mix. I remember when they were soooo trendy to use… as cakes. Now, there’s so much more to do with a cake mix!

      Thank you, Chelsea! I’m surprised my heart plate is still hanging around… it’s over 20 years old and have been my boys’ favorite plate all through the years. (And, that’s a lot of years!)

      Julianne, that was a lot of fun! Did you hear (or see) on the news how much snow we got while you were down in the valley… where it was raining?! It was crazy! Looks like you got a lot of info down there at the conference. Wish I could have kept my ticket…. 🙂

      Funny thing is, Elizabeth, is that the oatmeal totally disappears! At least that are the words when my son helped me bake this. I’m a frosting kind of girl, too! So, you would really dig this frosting!

    This cake looks fantastic! I can’t wait to try it out. Stopping by from SITS Girls Comment Love Tribe. Your photos are beautiful – what type of camera are you using? I’m in the market for a new one, and I’m taking all kinds of recommendations. Between the photos and the recipes … new follower! Have a great day.

      Thank you so much, Gailyc! I’m using the Canon T3i with the 50mm lens. I’ve been just winging it. I purchased the same camera for my oldest son 3 years ago when it came out. And, since I have no patience to read the manual… he has been giving me the low down. I bought mine off Amazon… they usually always have a great package deal! Let me know what kind you get… 😉
      Hope you’re having a great weekend!

      Laura, my sister is the same way when it comes to chocolate. In fact, when it comes to migraines, have you had your son use Past Tense Essential Oil (I use “do TERRA”)? I’m just letting you know that it has been the best thing EVER for me. My bro-in-law swears by this, too. We’d both go in to get botox(!) to help with the migraines… but this really works.
      Have a great weekend!

      You’re so funny, Heather! You are not the only one that is behind… I’m playing catch up today! So happy you stopped by to come say hi to little me! 😉
