Chocolate Whoopie Pie Cake is a delicious spin on the classic whoopie pie! A dense chocolate cake filled with a soft and pillowy marshmallow filling and drizzled in a chocolate ganache.
Hi, it’s Jenn, from Eat Cake For Dinner. Let me introduce you to one of the BEST cakes you will ever have. Seriously, I love this cake. Every layer of flavor is out of control delicious. A dense fudgy cake with a soft and pillowy marshmallow filling and creamy chocolate ganache. OMG!!!
It’s a cake version of a Whoopie Pie. Instead of a dense chocolate cookie with marshmallow filling, it’s a dense chocolate cake with marshmallow filling. I don’t know about you, but I would pick cake over a cookie any day of the week.
After my first bite of this DIVINE cake, I decided this would have to be my birthday cake this year and I did in fact make it for myself on my birthday :). It starts out with the easiest semi-homemade cake. I use this cake recipe all the time and switch up the cake mix and pudding flavor depending on my mood. This is the perfect go-to recipe to have on hand. Then, you will make an extremely creamy and fluffy marshmallow creme filling that is spread between the two layers of cake. Top it all off with a silky smooth chocolate ganache.
This is a really rich cake, so a small slice is plenty, but that won’t stop you from going back for multiple slices throughout the day!

- ¾ cup water
- ¾ cup vegetable or canola oil
- 4 large large eggs
- 1 cup sour cream, or Greek yogurt
- 1 teaspoon vanilla extract
Marshmallow Creme Filling
- 10 tablespoons unsalted butter, room temperature
- 1 (7-ounce) jar marshmallow creme

- 1 ½ teaspoon vanilla extract
- 2 cups powdered sugar, divided
Chocolate Ganache
- ½ cup chocolate chips, I used milk chocolate
- 3 tablespoons whipping cream
Instructions
Cake
- Preheat the oven to 350 degrees Fahrenheit. Generously spray a 12-cup bundt pan with non-stick cooking spray. Dust the inside with flour and set aside.
- In a large bowl combine 1 (15.25-ounce) box chocolate fudge cake mix,1 (3.9-ounce) box instant chocolate fudge pudding mix, ¾ cup water, ¾ cup vegetable or canola oil, 4 large large eggs, 1 cup sour cream, and 1 teaspoon vanilla extract. Mix until combined using an electric hand mixer.
- Pour batter into the prepared bundt pan and spread out evenly. It is a very thick batter. Bake for 45 minutes or until a toothpick inserted in the center comes out clean.
- Remove from oven and cool in pan for 10 minutes, then invert to a wire rack and cool completely. Once the cake is cool, slice it in half horizontally.
Cream Filling
- In a large bowl, combine the 10 tablespoons unsalted butter, 1 (7-ounce) jar marshmallow creme, pinch salt, and 1 ½ teaspoon vanilla extract. Mix until well combined using an electric hand mixer. Add one cup of powdered sugar and mix until combined. Add the remaining one cup of powdered sugar and mix until smooth and creamy. Spread the cream filling over the bottom half of the cake and place the top half of the cake over the cream filling.
Chocolate Ganache
- Place ½ cup chocolate chips, into a small bowl; set aside. Microwave 3 tablespoons whipping cream in a small, microwave-safe, dish until it starts to bubble. Pour the hot cream over the chocolate chips and allow to sit for 5 minutes. Stir together until smooth and creamy. If chocolate chips aren't completely melted. Place in the microwave and heat, stirring every 10 seconds until the mixture is smooth and the chocolate is melted.
- Pour the ganache over the cake then store the cake in the refrigerator. Bring it to room temperature before serving.

I’ve made this recipe many times and it always comes out perfect! I’ve used bundt pans, 13×9 and also doubled the recipe and used 2 15×10 pans to make for large crowds or church dinners. The chocolate taste in this cake is YUMMY!!!
I just made this for my sons birthday. It was delicious!!
I’m trying this today. How do I refrigerate it & how long does it take to get to room temperature from refrigerator. Planning on serving tomorrow. Looks delicious!
Made this cake, came out great an did not have a slice left over! I am curious about the nutritional information- is this over 3000 calories per slice? how many servings are in this cake.
Thank you for your comments! I am so glad that you enjoyed the cake. Yes, the serving size needed to be moved to 12 servings and not 4. Thank you for letting me know.
Made this twice now. My husband loves it. Grandkids do too. It always turns out perfect. Looks like I really fussed.
Is the marshmallow crème the same as marshmallow fluff?
Yes, it is.
hello I did this cake in 9 x 13 pan it is a little thin but it works. I split cake in half and filled it with cream filli9ng and poured melted chocalate over top. Looks fabulous and my “girls” at work will love it. thanks for greeat recipes, I love to bake and really prefer “normal” food.
this cake is so moist and rich, it is absolutely delicious! thanks for the recipe.
So pretty & looks delicious! Could I substitute a white cake & white chocolate pudding? Thank you!
I used 2-9” pie pans and cooked for 25 minutes!!!
Hi. For the Whoopi’s pie filling, is it possible to put it in between layers of the cake batter, and the cook, instead of baking the cake then adding the filling between the layers?
Thank you!
Can you make this in a 9×13 pan? And do two layers?
That is a great idea! I haven’t tried it with a 9×13 pan but it may be a little thinner cake rather than using the Bundt cake pan. Let me know how it turns out! Happy baking!! XOXO
This is one of the best cake I have ever seen. It looks so delicious, moist, and fluffy. I am loving it.
OH that is just what I love to hear!! Thanks so much for sharing! This is one of our family favorite cakes! xO
Can this be frozen? I’m making it now and I don’t think my husband and I will be able to eat it all!
When you specify marshmallow creme, is that the same as marshmallow fluff in a jar?
hey girl this looks amazing! Yummy!
