Whoopie Pie Cake with Chocolate Ganache

by Alli

Whoopie Pie Cake is so good AND easy to make – perfect for the holiday season! 

Time is something I seem to be running short of during the holiday season. What about you?

Recently, I sent a photo of my December monthly planner to my daughter and she couldn’t believe how many days of December are penciled in with something that needs to be done.

I have parties to plan, desserts to make, and family get-togethers galore. I wouldn’t have it any other way!

How to Make Whoopie Pie Cake

Thankfully, I’ve learned to work smarter and not harder.

When I’m entertaining and need a scrumptious dessert to wow my guests, I make Quick and Easy Whoopie Pie Cake with Chocolate Ganache.

I start with Marie Callender’s® Double Chocolate Chip Loaf Cake because it tastes homemade and is easy to make.

Plus, cleanup is a breeze! I finish off my dessert with Reddi-Wip® Real Whipped Cream because it’s made with real cream. You can find all the ingredients at your local grocery store!

The family will be getting together soon for a night of holiday movies. We’ll enjoy a casual soup and salad supper followed by Whoopie Pie Cake for dessert.

It’s so much easier to make than traditional individual whoopie pies and it’s a dessert that the entire family will enjoy.

Reddi-Wip is the perfect partner for my favorite holiday recipes. It’s made with real cream and is a delicious alternative to the non-dairy frozen toppings that are made with oils.
