In two bowls, stir together each cake mix with 2 eggs, ¼ cup oil, and ½ teaspoon vanilla. Mix until the texture is smooth and all dry bits are gone.

Grab a little bit of both doughs (strawberry and lemon), gently press together, and roll into a ball. Don't over-roll or mix them completely so the colors stay swirled.

Turn on your oven to 350°F (175°C). Cover baking sheets with parchment paper and place the dough balls 2 inches apart.

Bake 8-10 minutes. Edges should firm up while the centers stay soft—the cookies will finish setting as they cool.

Leave the cookies on the baking sheet for 2 minutes, move them to a cooling rack, and sprinkle powdered sugar on top once they've cooled completely.
