Peanut Butter Sauce and Chocolate Marshmallow Cupcakes

February 17, 2010

This peanut butter sauce recipe comes from my grandmother’s recipe box.  I don’t remember it which must mean she never made it, at least not while I was around, because there’s no way I could’ve forgotten such deliciousness.  This made a pretty big batch and that’s perfect for our house, since my husband is completely addicted to mixing ice cream and peanut butter for a midnight snack.

The cupcakes were an experiment, an idea that needs further experimentation.  The melted marshmallows make them more brownie-like, which isn’t a bad thing.  Just not what I was aiming for.  I don’t think I’ll have problem rounding up volunteer taste-testers for my next attempt.

For the Cupcakes:

  • Your favorite chocolate cake batter.  I used my standby Chocolate Cake because I could probably make it in my sleep without missing a thing.
  • Large Marshmallows

Line the muffin tin with paper or foil muffin cups and put a  marshmallow in each one.  Cover with cake batter.  I overfilled them and they spilled over and stuck to the pan. The marshmallows floated to the top.  Bake at 350.  I lost track of exactly how long they were in the oven, but at least 30 minutes.  Bake them until they spring back when you poke them.Let them cool on a rack and then take them out of the pans.For the Peanut Butter Ice Cream Sauce:

  • Light Brown Sugar, 1 cup, packed
  • Milk, 1/3 cup
  • Butter, 1 tablespoon
  • Corn Syrup, 3/4 cup
  • Smooth Peanut Butter, 1 cup

Combine everything but the peanut butter in a small, heavy saucepan.Cook over medium heat, stirring occasionally, just until the sugar is dissolved.

Ignore my dirty, dirty stove. Add the peanut butter and whisk until it’s smooth.  Make a little hole in the middle of a the cupcake and fill it with the sauce.  We used a spoon for this one but our thumbs worked just as well for the next ones.They’re a little messy to eat but they’re totally addicting!

don’t you know that when you write “Ignore my dirty ___”, more people will look for the dirty object haha! At first, I didn’t notice a dirty stove b/c I was too focused on what was in the pot, then I had to backtrack b/c of your comment haha.

Anyway, I love the idea of pouring the filling into the cupcake. These cupcakes look intensely good.

LOL! We’re in the middle of a “who’s going to clean the stove this time” standoff right now and I’m insisting it’s NOT my turn so I really don’t mind who notices. It might motivate someone else to finally clean it?!

Well, well, well. I think I might have a problem. I can see that I am going to make this peanut butter sauce a lot – probably way too much. I should thank you for the recipe, but this may start an unfortunate addiction…..

We’re already addicted here. I found the kids dunking Oreos in it the other day. Warm and drizzled over ice cream. Straight out of the bowl. So many ways to enjoy…

Karen, wish I would have had this recipe last week when I was snowbound at home. We could have plowed through a batch of these in no time. I can’t wait to give these a try.

i think this is my favorite ice cream sauce EVER! I’m doing make-your-own sundae bar for my mom’s birthday dessert and this is the perfect addition. Thank you for sharing your grandmother’s recipe with us!
