    Does it have to be shortening or can it be oil for the peanut butter cake and apple cake.For the peanut butter frosting what is the tablespoons of mild

  3. Chassie

    If you don't have vegetable shortening can you substitute vegetable oil since you're melting it anyway?

  4. Joanne

    This looks delicious...and simple!! (Wonder what it would taste like if we made the icing chocolate????)

    This cake looks and sounds amazing! I have just tried baking it and it wasent a success :-(
    I followed the recpie to the letter, the batter was very runny and after 25mins it was nowhere near cooked I ended up having to leave it in for 60mins before the toothpick came out clean.
    Im wondering if I used more flour? maybe three cups instead of 2 might this help the issues I have had?

      Update: once cake was cooled and iced the cake had sunk, when I cut into it and it was dense, it almost looked uncooked😐, such a shame. Wish I could post a picture. Had to bin it!😟
      Reading the recpie again, maybe i should reduce the amount of water?

    My Mom made the best peanut butter cupcakes with the best peanut butter frosting. She died in 1973 and no one in my family has the recipe, so I'm hoping that this is the one that tastes like hers. There is one more thing that she baked for us, that I don't have a recipe for, is her Thumbprint Cookies. I was 8 years old when she died, and I will turn 51 years old next month, but when you spend a lot of time in the kitchen, while your mom is cooking, you remember a lot of things and these are the memories that you have for the rest of your life!

    Turned out great. Halved and put into square glass 8x8 used underfilled cups of whole wheat flour. Used vanilla bean and some almond in the frosting. Topped with dried blueberries :) cooked at 350 for around 25 min.
