Preheat your oven to 375°F (190°C) and prepare your baking sheet.

In a large mixing bowl, whisk together the all-purpose flour, cornmeal, brown sugar, baking powder, and salt until uniformly combined.

In a separate bowl, combine buttermilk, softened butter, and egg, mixing until well incorporated.

Gently fold the wet ingredients into the dry mixture until just combined, then stir in diced jalapenos.

Drop tablespoon-sized amounts of the batter onto the prepared baking sheet and bake for 12-15 minutes.

Allow the whoopie pie bases to cool on the baking sheet for about 3-5 minutes, then transfer to a wire rack.

In a mixing bowl, blend goat cheese, cream cheese, and whole milk until smooth. Fold in bacon and chopped chives.

Spread or pipe about 1 tablespoon of the creamy filling onto half of the cooled cornbread pieces and top with the remaining pieces.
