Marshmallow Hot Chocolate Bundt Cake #bundtbakers

I joined a blogging group called the #BundtBakers recently. Each month we get to bake a Bundt cake along a theme. For my first outing, the theme is beverages, and what with it being chilly weather now, naturally the idea of Hot Chocolate comes up. And who doesn’t like their hot chocolate with a dollop of marshmallow creme or mini marshmallows? Would you like both? (Please!)

When I joined the group I thought it might help further my baking skills. I don’t bake cakes that often. I had a Bundt pan that was about thirty years old. Had? I still have it. But I did go buy a swirled Nordicware pan which is slightly smaller.

The recipe was inspired by a cake on Betty Crocker where I saw the photo with beautifully done drizzles of marshmallow creme and ganache. I did use the ganache, ended up having extra. You might be able to cut this part of the recipe in half. I looked at two cake recipes: one from Carol Bass of Recipezazz and another which was a Twinkie cake from Leite’s Culinaria. I liked the filling on the Twinkie cake. The cake itself had to be cut back due to the smaller size. It required changes in the amounts of ingredients (eggs, cocoa, etc.) and I declined the use of oil in my cake. I was going to use the marshmallow filling from David Leite verbatim, although a smaller amount. That didn’t work out for me and I compensated with additional marshmallow creme and confectioner’s sugar to stiffen it up. If I did this again I would start with about half of the butter and see how that went.

The cake turned out pretty good. I of course can’t eat much of it being diabetic but I did have a taste. Very chocolaty and I count it as a success. Bill liked it and said it reminded him of hot chocolate and said he didn’t think it was too sweet with all the topping, probably because of the bittersweet chocolate. Something like milk chocolate would probably be too much.

It’s a bit big for just two people but I have an adoring posse of fans who always looks for extra food from me. Feed the world, they say. And I do.

Marshmallow Hot Chocolate Bundt Cake

  • 1 1/2 cups all-purpose flour
  • 3/4 cup unsweetened cocoa
  • 2 teaspoons baking powder
  • 1/2 teaspoon salt
  • 3/4 cup unsalted butter, softened
  • 1 1/3 cups sugar
  • 1 teaspoon vanilla
  • 2 large pastured organic eggs plus one yolk
  • 1 cup whole buttermilk

Marshmallow Creme Filling

  • 1 (7 ounce) jar marshmallow creme
  • 6 tablespoons melted butter, cooled
  • 2 tablespoons powdered confectioner’s sugar
  • 1 teaspoon vanilla

Chocolate Ganache:

  • 1/3 cup whipping cream
  • 2 tablespoons unsalted butter, cut into small pieces
  • 4 ounces bittersweet chocolate, finely chopped

Garnish and Tools:

  • 1/2 cup dehydrated marshmallow bits
  • 1/4 cup bittersweet chocolate, in curls or finely chopped
  • 10 cup Bundt pan
  • apple corer
  • electric mixer


  1. Preheat oven to 325ºF.
  2. Spray a 10 cup Bundt pan with  baking  release spray, or grease and flour, shaking out excess.
  3. Sift together the flour, cocoa, baking powder and salt in a small bowl and set aside.
  4. Place the softened butter, sugar and vanilla into the bowl of a stand mixer and cream together with paddle attachment until smooth, then adding eggs one at a time, continuing to beat until smooth again.
  5. With the mixer on low, add amounts of buttermilk and sifted flour mix alternatively until it is all incorporated; continue beating a few minutes until smooth.
  6. Pour mixture into a prepared Bundt pan and bake at 325ºF.  for 45-55 minutes, or until a toothpick can be removed cleanly.
  7. Cool cake while preparing marshmallow creme and ganache, keeping the cake in the baking pan.
  8. To prepare the marshmallow filling, place whip attachment in the bowl of your electric mixer and whip the marshmallow creme, butter, powdered sugar and vanilla until thick and smooth but not runny. Add more sugar if you need to stiffen it up.
  9. Take the apple corer and bore holes in about 8 places around the top of the cake, going deep but not all the way through; reserve the cake bits to patch the holes later.
  10. Place marshmallow filling in a pastry bag or other filling tool and pipe the filling into the holes. You will have extra; use that for garnishing the cake.
  11. Turn cake out onto a cake plate.
    Prepare ganache by putting the chopped chocolate, cream, and the butter in a microwavable bowl and microwave on high for thirty seconds, stir, microwave an additional 15 seconds, and then stir until completely melted and smooth. 
  12. Drizzle remaining topping and ganache over the cake as a drizzle; you may not use it all if you don’t want to; sprinkle with dehydrated mini marshmallows and chocolate curls.
