Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper or silicone baking mats.
In a large mixing bowl, combine the yellow cake mix and all-purpose flour. Stir to evenly distribute the flour.
Add the eggs, milk, vegetable oil, and 1/4 cup of the peanut butter to the dry ingredients. Use a hand or stand mixer to beat until a smooth, thick batter forms.
Using a cookie scoop or a tablespoon, drop rounded dollops of batter onto the prepared baking sheets, spacing them about 2 inches apart. Aim for uniform sizes to ensure the whoopie pies match when sandwiched together.
Bake in the preheated oven for 8–10 minutes, or until the tops of the cookies spring back when lightly touched. Allow to cool on the baking sheets for 5 minutes before transferring to a wire rack to cool completely.
Prepare the peanut butter filling by combining the softened butter, remaining 1/2 cup peanut butter, powdered sugar, and vanilla extract in a bowl. Beat with a mixer until light, fluffy, and smooth.
Assemble the whoopie pies by spreading or piping a dollop of the peanut butter filling onto the flat side of one cookie. Spread 1 teaspoon of jelly on the flat side of a second cookie, then sandwich the two together.
Repeat with the remaining cookies, filling, and jelly to create 12 whoopie pies.
Serve immediately or store in an airtight container at room temperature for up to 2 days.
