1/4 tsp Salt

1 tsp Baking Soda

1 Tbsp Ground Cinnamon

a pinch Ground Nutmeg

Pumpkin Pie Spice, to taste

1 can Pumpkin Purée

4 Sticks Butter or Margarine, Softened, Divided Use

2 Whole Eggs

1/2 Cup Whole Milk or Half And Half or Heavy Cream

1 tsp Vanilla Extract

1/2 Cup Water

1 Cup Confectioners’ Sugar

1 container Marshmallow Fluff

1/2 Cup Semisweet Chocolate Chips

For the pumpkin sheet cake:

1. Preheat the oven to 350 degrees F.

2. In a medium bowl, combine flour, 1 1/3 cups of granulated sugar, salt, baking soda, ground cinnamon, ground nutmeg, and pumpkin pie spice, and stir in pumpkin purée.

3. In a separate bowl, whisk together 2 sticks of butter, eggs, whole milk, and vanilla extract, and stir it into the cake batter.

4. Pour the cake onto a well greased baking sheet lined with parchment paper, and bang it before putting it in the oven to release the air bubbles.

5. Bake for about 25 minutes. A toothpick inserted into the center should come out clean when the cake is done.

6. Remove from oven, and let cool.

For the marshmallow-candy American buttercream frosting:

1. In the bowl of an electric mixer, cream together 1 stick of butter and Confectioners’ sugar in a bowl on low speed until everything is thoroughly combined.

2. In a saucepan, melt remaining butter, and stir in marshmallow fluff.

3. Slowly pour it into the bowl with the frosting base one spoonful at a time along with chocolate chips, crushed Reese’s peanut butter cups (if using), crushed M&Ms, crushed Oreo cookies, crushed nuts (if using), crushed graham crackers, and crushed chocolate granola, and let the mixer go until everything is incorporated.

For the simple syrup:

1. In a saucepan, dissolve remaining granulated sugar in water, and bring to a boil. Bring the simple syrup to a simmer, and set aside.

For the finished sandwiches:

1. Cut different shapes out of the cake, and brush the simple syrup on half of them. Spoon marshmallow-candy American buttercream frosting onto the ones with simple syrup, top the ones that have it on them with their matching cake shapes, and enjoy.

Yields: about 10 Halloween spiced pumpkin sheet cake whoopie pies with marshmallow-candy American buttercream frosting filling
