Martha Stewart's Peanut Butter Jelly Cupcake

If you've always loved a good peanut butter jelly sandwich and if you are not averse to a luxuriously rich buttery cake, I suggest you bookmark this and bake it at the first opportunity you have. This cupcake is gloriously addictive and beats Magnolia Bakery's Cupcake hands down effortlessly!

So far, I've had pretty good results with the recipes from Martha Stewart's Cupcakes. I only wish I have the time to bake every single one of them. (See here , here and here for the recipes I have tried...)
The recipes are in general not too sweet though I normally still try to tune down the amount of sugar used. I like it that Martha Stewart's book features a good collection of more adult and classic cupcake flavours and design.


This cupcake is moist and delicious enough to eat on its own. The incorporation of coarsely chopped roasted salted peanuts adds lovely texture to every bite but the creamy peanut butter frosting is one icing on the cake that takes you to the realm of cake-bliss. I would gladly lick the frosting from a spoon.

However, be warned, the deliciousness is the result of copious use of sour cream, thick cream,cream cheese and of course, creamy peanut butter! However, your inhibition gets lost at first bite. So enjoy and worry later!
