Chocolate Marshmallow Whoopie Pies – a kid favourite for lunch boxes, after school snacks and birthday parties. Everyone loves the marshmallow frosting inside!
There are a couple of other whoopie pie recipes on this blog and this one is just a different version of the classic chocolate whoopie pie, using the marshmallow type frosting that we so often use on Black and White Cake.
This is the most popular version I make, especially with my kids. I’ve often make platters of these to bring to birthday or school parties for the kids and they disappear almost immediately!

Course:
Cookies
Servings: 1 1/2 dozen whoopee pies
Ingredients
For the Whoopie Pie Cake
- 4 heaping cups sifted flour
- 2 teaspoons salt
- 2 teaspoons baking soda
- 1 cup cocoa
- 2 cups sugar
- 1 cup hot water
- 1/2 cup butter
- 1/2 cup shortening
- 1 cup sour milk
- 2 eggs
- 1 teaspoon genuine vanilla extract
For the Marshmallow Frosting
- 3 egg whites
- ¼ tsp cream of tarter
- 2 tsp vanilla extract
- 1 cup sugar
- ½ cup corn syrup
- 3 tbsp water
Instructions
To prepare the whoopee pie cake batter
-
Mix together shortening, butter, sugar, eggs and vanilla.
-
Sift together dry ingredients and set aside.
-
Add milk, cocoa and hot water. Then add the dry ingredients.
-
Scoop large rounded spoonfuls of batter onto a greased cookie sheet and space at least 2″ apart. An ice cream scoop works well for this purpose too. Bake at 350 degrees for 12-15 minutes or until centers spring back when touched. Cool completely.
To prepare the marshmallow frosting
-
In a small saucepan combine sugar, corn syrup and water. Bring to a boil over medium heat and continue to cook until the mixture reaches 240 degrees F on a candy thermometer or when a teaspoonful of the mixture dropped into ice water forms a soft ball that holds its shape when cool.
-
Whip the egg whites, cream of tartar and vanilla extract to soft peaks in a large bowl. With the mixer on medium high speed, slowly begin to pour the sugar syrup down the side of the egg white bowl in a thin continuous stream. Continue to whip the frosting until it forms stiff peaks.
