Stepwise Method: Banana Whoopie Pies

Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Line your baking sheets with parchment paper to prevent sticking.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking powder, 1 teaspoon of baking soda, 1 teaspoon of salt, and 1 teaspoon of ground cinnamon. Set this mixture aside.
Step 3: Cream Butter and Sugars
In a large mixing bowl, cream together 8 tablespoons of softened unsalted butter, 1 cup of granulated sugar, and 1 cup of packed light brown sugar until light and fluffy.
Step 4: Add Egg and Bananas
Add 1 large egg and 2 ripe bananas (mashed, about 1 cup) to the butter-sugar mixture. Beat until well combined.
Step 5: Incorporate Sour Cream and Vanilla
Mix in 1 cup of sour cream and 1 teaspoon of pure vanilla extract until everything is fully incorporated.
Step 6: Combine Dry and Wet Ingredients
Gradually add the dry ingredients to the wet mixture, mixing until just combined. Be careful not to overmix!
Step 7: Scoop the Batter
Using a cookie scoop, drop rounded tablespoons of batter onto your prepared baking sheets, leaving space between each for spreading.
Step 8: Bake
Bake in the preheated oven for about 12-15 minutes, or until the edges are lightly golden and a toothpick comes out clean. Remove from the oven and let them cool on the baking sheets for a few minutes before transferring to a cooling rack.
Step 9: Prepare the Filling
While the whoopie pies are cooling, prepare the filling. In a mixing bowl, beat together 2 cups of mascarpone at room temperature with 4 tablespoons of sugar until smooth and creamy.
Step 10: Assemble the Whoopie Pies
Once the whoopie pies are completely cooled, spread a generous dollop of the mascarpone filling on the flat side of one pie and top it with another pie, flat side down. Repeat with the remaining pies.
Spring–Summer–Fall–Winter Ideas

- Spring: Add a hint of lemon zest to the mascarpone filling for a refreshing twist.
- Summer: Serve with a scoop of vanilla ice cream in between the whoopie pies for a decadent dessert.
- Fall: Incorporate chopped nuts or a pinch of nutmeg into the batter for added flavor.
- Winter: Drizzle melted chocolate over the assembled pies for a rich touch.
Mistakes Even Pros Make
- Overmixing the batter can lead to tough whoopie pies, so mix just until combined.
- Not allowing the whoopie pies to cool completely before filling can result in a melty mess.
- Forgetting to measure the bananas can throw off the moisture balance.
- Using cold mascarpone can make it difficult to achieve a smooth filling.
Cooling, Storing & Rewarming
Allow your Banana Whoopie Pies to cool completely before storing. Place them in an airtight container in the refrigerator for up to 5 days. If you want to enjoy them warm, simply pop them in the microwave for a few seconds or let them sit at room temperature for a bit.
FAQ
