July 17, 2026 – For many, childhood treats hold a special place in memory, evoking a sense of comfort and joy. For Alissa Saenz, creator of the popular vegan food blog Connoisseurus Veg, the whoopie pie has been a long-cherished, yet elusive, memory. Having adopted a vegetarian lifestyle at the age of thirteen, Saenz found herself reminiscing about the classic American confection, particularly the versions she’d admired from Amish bakers at farmers’ markets for over three decades. While her commitment to meat-free living remained unwavering, the allure of a soft, cake-like sandwich with a creamy filling proved a tougher culinary mountain to scale.

This week, Saenz unveiled a triumphant solution: a meticulously crafted recipe for Vegan Whoopie Pies, promising to deliver all the nostalgic delight of the original without any animal products. This culinary innovation is not just a personal victory for Saenz, but a significant offering to the growing community of plant-based eaters seeking to recapture cherished flavors.

The Quest for the Perfect Vegan Filling

The primary challenge in veganizing traditional whoopie pies, as Saenz explains, lies in replicating the signature marshmallow-like filling. While she has successfully adapted other marshmallow-centric desserts, such as vegan Rice Krispie treats, ambrosia salad, and s’mores cookies, using readily available vegan marshmallows, this particular application proved more complex.

"Sadly, vegan marshmallows didn’t work for my whoopie pie filling," Saenz shares in her detailed blog post. "It turned into a big, clumpy marshmallow mess." This setback, however, did not deter her. Instead, it spurred a creative pivot, leading to the development of an entirely new filling strategy.

The breakthrough came by adapting her existing vegan ermine frosting recipe, a technique often used in classic American cakes. This rich, creamy frosting, when chilled, provides the ideal texture and flavor to sandwich between the chocolate cake rounds. The result, Saenz declares, is a filling that is not only a successful vegan substitute but an "absolute joy to devour," bringing back the delight she’d been missing for nearly thirty years.

A Harmonious Blend of Chocolate and Vanilla

The Vegan Whoopie Pies are a testament to Saenz’s dedication to creating plant-based versions of beloved comfort foods. The recipe is divided into two key components: the tender, rich chocolate cake rounds and the luxuriously fluffy vanilla filling.

The chocolate cake batter is crafted using a flax egg – a common vegan binder made from ground flaxseed and non-dairy milk – which ensures a moist and tender crumb. Dry ingredients, including flour, cocoa powder, and leavening agents, are combined with a wet mixture of vegan butter, sugar, vanilla, and additional non-dairy milk. The resulting batter is described as being a thick, fluffy consistency, somewhere between traditional cake batter and cookie dough, perfect for dropping into uniform rounds.

The vanilla filling, the star of this vegan reinvention, begins with a roux. This thickening agent is made by whisking flour, sugar, non-dairy milk, and coconut milk together and simmering until it reaches a thick consistency. Once cooled, this base is whipped with vegan butter, shortening, and vanilla extract, transforming it into a light, airy, and irresistibly smooth frosting.

The Baking Process: A Step-by-Step Guide to Nostalgia

Saenz provides a comprehensive guide to creating these delectable treats, demystifying the process with clear instructions and helpful tips.

Step 1: Preparing the Filling Base (Roux)
The process begins with the roux for the filling. Flour, sugar, non-dairy milk, and coconut milk are combined in a saucepan and brought to a simmer over medium heat. As the mixture thickens, it’s crucial to whisk continuously to prevent lumps. Once thickened, it’s removed from the heat and allowed to cool. To prevent a skin from forming, it’s recommended to either cover it directly with plastic wrap or whisk it occasionally.

Step 2: Crafting the Chocolate Cake Batter
Simultaneously, the chocolate cake batter is prepared. A flax egg is made by combining ground flaxseed with non-dairy milk and letting it sit. The dry ingredients – flour, cocoa powder, optional espresso powder (which enhances the chocolate flavor), baking powder, baking soda, and salt – are whisked together. In a separate bowl, vegan butter, sugar, and vanilla are creamed, followed by the flax egg and the remaining non-dairy milk. The dry ingredients are then gradually beaten into the wet mixture until a thick, fluffy batter forms.

Step 3: Shaping and Baking the Cake Rounds
Using a cookie scoop for consistency, dollops of the chocolate batter are placed onto parchment-lined baking sheets. Saenz reassures bakers that perfection in shaping isn’t essential, as the cakes tend to round out during baking. The rounds are then baked until they have spread and puffed up, and a gentle press springs back.

Step 4: Creating the Fluffy Vanilla Filling
While the cake rounds cool, the filling is made. Vegan butter and shortening are creamed together with vanilla extract. The cooled roux is then gradually beaten into the butter mixture, resulting in a creamy and fluffy filling.

Step 5: Assembling the Whoopie Pies
Once the cake rounds are completely cooled, the assembly begins. About two tablespoons of the vanilla filling are placed on the flat side of one chocolate cake round, and another cake round is gently pressed on top. For a more polished look, Saenz suggests using a piping bag, though a spoon works just as effectively.

Storage and Variations: Ensuring Enduring Delight

For those who can’t devour all the whoopie pies at once, Saenz offers practical storage advice. The vegan whoopie pies can be stored in an airtight container in the refrigerator for up to four days. For longer storage, they can be frozen for up to three months. To prevent sticking, it’s recommended to store them in a single layer or separate stacked layers with parchment paper. Thawing overnight in the refrigerator or at room temperature for about 30 minutes ensures they are ready to be enjoyed.

While the classic chocolate and vanilla combination is a guaranteed crowd-pleaser, Saenz also hints at potential variations, encouraging bakers to experiment with different flavor profiles. This opens the door for creativity, allowing for adaptations such as adding peppermint extract to the filling for a festive twist or incorporating a hint of orange zest into the chocolate cakes.

A Culinary Milestone for Plant-Based Desserts

The unveiling of these Vegan Whoopie Pies represents more than just a new recipe; it signifies a significant step forward in the world of vegan baking. It demonstrates that beloved, nostalgic treats can be recreated with precision and flavor, even when traditional ingredients are unavailable. Alissa Saenz’s dedication to her craft and her commitment to sharing delicious, plant-based alternatives continue to inspire home bakers and dessert enthusiasts alike. These whoopie pies are not just a sweet indulgence; they are a delicious reminder that culinary boundaries are constantly being pushed, and that cherished flavors can indeed be enjoyed by everyone.
