PEANUT BUTTER SHEET CAKE
My older sister Susan and her husband had a tough time getting pregnant. That’s saying it mildly. They did in vitro fertilizationfive times! FIVE!
Can you just see the dollar signs when I say that? The fifth time it finally worked. They had a beautiful daughter that they named Jewels. They probably should have named her Mercedes after all that money.
In the early stages of her pregnancy the doctorstold her that in order to increase her chances ofthe embryo implantingsuccessfully she needed to consume a lot of calories.
She did exactly that.
Oh how I was secretly jealous of herfree hall pass to eat anything and everything.But the secret, in my opinion, wasin the peanut butter. She ate a jar of peanut butter a week…just by the spoonfuls.
This recipe comes from Nina Jones, a reader of this blog, who said after reading my blog she immediately thought of this recipe to send me. Thank you!
These are definitely for peanut butter lovers or those trying to conceive (ha-ha).
It’s surprisingly lighter than I thought (I was expecting a heavy bar for some reason)and not too sweet. Don’t laugh…I know my sweet scale is a little higher notched than most but I really enjoyed it.
EASY BUTTERMILK SUBSTITUTION
For every cup of buttermilk needed, add one tablespoon lemon juiceor white vinegar to a liquid measuring cup, and add enough milk until it measures 1 cup. Stir, and let sit for five minutes before using.
The key to this cake is to NOT overbake it! It’s moist unless you cook it too long.

Everything about this is delicious and came together perfectly. The cake reminds me of the cake the Lunch Ladies would prepare for lunchtime at school – my favorite day to eat in the cafeteria when this was on the plate. 🙂 So glad to come across your recipe. I love that this bakes up in 15ms! Perfect for the get-together I was running late for. 🙂 Thank you for sharing!
