The Ultimate Peanut Butter Whoopie Pie

The scent of peanut butter always takes me back to childhood summers. I remember my grandmother, a woman of few words but incredible baking skills, used to make peanut butter cookies for us. They were simple, rustic, and undeniably delicious. One time, she attempted whoopie pies, but the filling wasn’t quite right. It was too runny, and the pies slid apart like a comedic vaudeville act. We laughed, she shrugged, and we ate them anyway. This recipe captures the essence of those memories – the nutty aroma, the comforting sweetness, and the determination to create the perfect peanut butter whoopie pie that even my grandmother would approve of.

Ingredients

For the Pies:

• 1/2 cup Crisco Baking Sticks Butter Flavor Shortening, plus additional for greasing (or 1/2 cup butter flavor shortening)
• 1 cup nonfat milk (recipe calls for whole milk)
• 1 tablespoon white vinegar
• 1 cup granulated sugar
• 1 cup firmly packed brown sugar
• 3/4 cup crunchy peanut butter
• 1 cup water, boiling
• 1 teaspoon vanilla extract
• 4 cups all-purpose flour
• 1/2 cup unsweetened cocoa powder
• 2 teaspoons baking soda
• 1/2 teaspoon baking powder
• 1/2 teaspoon salt

For the Filling:

• 1/2 cup nonfat milk
• 3 tablespoons all-purpose flour
• 2 cups confectioners’ sugar
• 1/2 cup Crisco Baking Sticks Butter Flavor Shortening (or 1/2 cup butter flavor shortening)

Equipment Needed

• Baking sheet
• Mixing bowls (large and medium)
• Electric mixer
• Small microwavable bowl or small saucepan
• Measuring cups and spoons
• Whisk
• Spatula
• Cooling racks or foil sheets

Instructions

1. Preheat your oven to 425°F (220°C). Prepare a baking sheet by lightly greasing it with shortening. Line your countertops with foil sheets for cooling the baked pies.
2. In a small, microwavable bowl, combine 1 cup of nonfat milk and 1 tablespoon of white vinegar. Microwave on HIGH until slightly warmed. Alternatively, warm the mixture in a small saucepan over medium heat on the stovetop. The mixture should appear slightly separated and curdled – this is exactly what you want!
3. In a large bowl, combine 1 cup of granulated sugar, 1 cup of firmly packed brown sugar, and 3/4 cup of crunchy peanut butter. Using an electric mixer, beat the ingredients together at medium speed until the mixture becomes crumbly.
4. Measure out 1/2 cup of shortening into a 2-cup glass measuring cup. Pour 1 cup of boiling water over the shortening and stir until the shortening is completely melted.
5. Add the melted shortening mixture to the peanut butter mixture in the large bowl, along with the milk and vinegar mixture and 1 teaspoon of vanilla extract. Beat at low speed. The mixture will appear very fluid and might look a bit separated – don’t worry, this is normal.
6. In a separate bowl, whisk together 4 cups of all-purpose flour, 1/2 cup of unsweetened cocoa powder, 2 teaspoons of baking soda, 1/2 teaspoon of baking powder, and 1/2 teaspoon of salt. Stir well to ensure even distribution of the dry ingredients.
7. Add the dry ingredients all at once to the peanut butter mixture. Beat at low speed until the mixture is just blended and resembles a thick cake batter.
8. Let the batter stand for 20 minutes. This allows the gluten to relax and will contribute to a more tender whoopie pie.
9. Drop the batter by rounded measuring tablespoonfuls, leaving about 2 inches of space between each one, onto the prepared baking sheet.
10. Bake in the upper half of the preheated oven for 8 to 10 minutes, or until the pies are set. Take care not to overbake! Overbaking will result in dry, crumbly pies. A toothpick inserted into the center should come out clean.
11. Allow the baked pies to cool for 2 minutes on the baking sheet before transferring them to the prepared foil sheets to cool completely.
12. While the pies are cooling, prepare the filling. In a small saucepan, combine 1/2 cup of nonfat milk and 3 tablespoons of all-purpose flour. Cook and stir over medium heat until the mixture thickens into a smooth, pudding-like consistency.
13. Allow the filling to cool completely. This is crucial, as adding warm filling to the confectioners’ sugar will result in a melted mess.
14. Once the filling has cooled, transfer it to a medium bowl. Add 2 cups of confectioners’ sugar and 1/2 cup of shortening. Beat at low speed until just blended. Then, beat at high speed until the filling is smooth and fluffy.
15. Refrigerate the filling until you’re ready to assemble the whoopie pies. This will help it firm up and make it easier to spread.
16. To assemble, spread a generous amount of filling on the flat side of one pie half. Top with another pie half, pressing together gently to distribute the filling evenly. Repeat with the remaining pie halves and filling.

Expert Tips & Tricks

• Don’t overmix the batter. Overmixing develops the gluten in the flour, resulting in tough whoopie pies. Mix until just combined.
• Use a cookie scoop for even-sized pies. This ensures consistent baking and a more uniform appearance.
• Adjust baking time based on your oven. Ovens can vary, so keep a close eye on the pies during baking. They are done when they spring back lightly when touched.
• For a richer flavor, use brown butter shortening. The nutty aroma will enhance the overall peanut butter taste.
• Make the filling ahead of time. The filling can be made a day or two in advance and stored in the refrigerator.
• If your filling is too thin, add more confectioners’ sugar, a tablespoon at a time, until it reaches the desired consistency.
• If your filling is too thick, add a teaspoon of milk at a time until it thins slightly.

Serving & Storage Suggestions

These peanut butter whoopie pies are best served slightly chilled. They make a delightful treat with a glass of cold milk or a warm cup of coffee.

• Storage: Store assembled whoopie pies in an airtight container in the refrigerator for up to 3 days.
• Freezing: You can freeze the baked pie halves (without the filling) for up to 2 months. Wrap them tightly in plastic wrap and then place them in a freezer-safe bag. Thaw completely before filling. The filling can also be frozen separately in an airtight container for up to 1 month. Thaw and re-whip before using.
• Room Temperature: These can be stored at room temperature if you intend to eat them within 12 hours.

FAQs (Frequently Asked Questions)

Q: Why did my whoopie pies spread out too thin?
A: The batter was likely too wet. Make sure you measure your ingredients accurately, especially the liquids. Letting the batter rest for 20 minutes helps to thicken it.

Q: My whoopie pies are dry. What did I do wrong?
A: You probably overbaked them. Reduce the baking time by a minute or two and check for doneness more frequently.

Q: Can I use natural peanut butter?
A: Yes, but be aware that natural peanut butter tends to be oilier. You might need to adjust the amount of liquid in the recipe slightly. Stir the peanut butter thoroughly before measuring.

Q: How do I prevent the filling from squeezing out when I assemble the pies?
A: Don’t overfill the pies. Use a moderate amount of filling and press the halves together gently.

Q: Can I add other extracts to the batter or filling?
A: Absolutely! A few drops of almond extract or maple extract would complement the peanut butter flavor beautifully.
