Common Questions
Do I need to chill pumpkin whoopie pies before serving?
You do not have to, but it is the most important step for neat sandwiches. Chilling for at least 1 hour firms up the cream cheese filling so it stays put when you bite in.
How do I keep the filling from squishing out?
Three things help the most: cool the cakes completely, use a thick filling (chill it 20 to 30 minutes if it feels soft), and chill the assembled pies before serving. Also, pipe a ring around the edge and fill the center, then gently press. If you press like you are flattening a burger, the filling will behave like one.
Can I use pumpkin pie filling instead of pumpkin puree?
Use 100% pumpkin puree, not pumpkin pie filling. Pumpkin pie filling is pre-sweetened and already spiced, which throws off both flavor and texture.
What spices go in pumpkin whoopie pies?
This recipe uses cinnamon, ginger, nutmeg, and cloves. If you want a shortcut, you can substitute 3 to 3 1/2 teaspoons pumpkin pie spice for the individual spices (start with 3 teaspoons if you like it a little milder).
Why did my whoopie pie cakes turn out flat?
Common causes are overmixing (which can make them tougher and can affect rise and shape), old baking soda or baking powder, or a batter that sat too long once the wet and dry were combined. Scoop and bake right away, and mix only until the flour disappears.
Can I make these without a piping bag?
Absolutely. Use a zip-top bag with the corner snipped, or simply spread the filling with a small offset spatula. Just keep the filling thick and chilled.
