Method
Make the strawberry cakes
- Heat the oven to 350°F.
- Line two 18x13-inch rimmed baking sheets with parchment paper.
- Grind the freeze-dried strawberries into a fine powder.
- Whisk the strawberry powder with the flour, baking powder, baking soda, and salt in a medium bowl.
- Beat the butter and granulated sugar in a large bowl until light and fluffy, about 2 minutes.
- Beat in the egg and vanilla until combined.
- Add the flour mixture in three additions, alternating with the buttermilk in two additions, mixing on low just until combined.
- Drop the batter in 1 1/2-tablespoon portions onto the prepared sheets, spacing them about 2 inches apart.
- Bake for 11–13 minutes, switching the sheets between oven racks halfway through, until the tops spring back when lightly touched.
- Cool the cakes on the sheets for 5 minutes.
- Transfer the cakes to a wire rack to cool completely.
Make the cream filling and assemble
- Beat the cream cheese and butter in a medium bowl until smooth.
- Beat in the powdered sugar and vanilla.
- Add the heavy cream and beat until fluffy.
- Spread or pipe the filling onto the flat side of half the cooled cakes.
- Top with the remaining cakes.
- Refrigerate the whoopie pies for 30 minutes to set the filling.
- Keep any leftovers refrigerated.
Notes
For neat, even cakes, portion the batter consistently and let the cakes cool completely before filling. Refrigerate leftovers for up to 3 days; freeze assembled whoopie pies for up to 2 months and thaw in the refrigerator. For a gluten-free variation, use a cup-for-cup gluten-free flour blend.
