Today is a National holiday. Well, not really, but it’s my birthday. I actually declare this my “birthday week” and celebrating with Spice Cake with Peanut Butter Frosting!
I am not one of those people that don’t tell anyone about my birthday or lie about my age. Half the time I have to ask John how old we are.
He’s 11 days older than me, a fact that I never let him forget.
John came home for lunch and I told him I was making a buttermilk spice cake with peanut butter frosting for my birthday. It was my favorite birthday cake when I was young, and I haven’t had it in over 35 years.
He said had he known, he would have made me one every year. How can you not love a boy that says stuff like that?
I’m not sure what recipe my mother used but I found this recipe in my MIL recipe box. It’s actually called a New Duchess Spice Cake. I knew it would be good when I saw all of the spices and buttermilk listed in the ingredients.
This recipe required me to sift the dry ingredients together and then add the wet ingredients and lastly the eggs. I generally make a cake in the opposite order but went with the instructions.
The only change that I made was to replace the shortening with butter…insert singing here.
Don’t forget to pin this recipe to your favorite dessert board!
I don’t know where my MIL got this recipe, but it isn’t unique. I was able to find this cake and variations for it so not sure who the initial creator was but I’m applauding them whoever they are.
Eating this cake made me feel like a Happy Duchess, and I will definitely make it again!
- You can bake this cake in a 9×13 pan if you don’t want to make a layered cake.
- This cake would also be delicious with cream cheese or buttercream frosting if you aren’t feeling adventuresome.
- Anytime you use an icing with milk, butter or cream cheese the cake should be covered and stored in the refrigerator.
