Prep & Preheat: Spray two 4-ounce ramekins generously with nonstick cooking spray and place them on a small baking sheet. Preheat your oven to 350°F (175°C).

Mix the Wet Ingredients: In a medium bowl, whisk together the egg, sugar, oil, and vanilla extract until smooth and well combined.

Combine the Dry Ingredients: In a small bowl, whisk the flour, baking powder, and salt.

Form the Batter: Gradually fold the dry ingredients into the wet ingredients in two additions, alternating with the milk (adding 1 tablespoon at a time). Stir gently until just combined.

Add Some Cheer: Gently fold in the Christmas sprinkles, ensuring they’re evenly distributed.

Bake: Divide the batter evenly between the prepared ramekins. Bake for 20 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes cool completely in the ramekins.

Make the Frosting: In a small bowl, beat the cream cheese, powdered sugar, and vanilla extract with an electric mixer until smooth. Add a splash of heavy cream if needed to achieve a spreadable consistency.

Frost & Decorate: Remove the cooled cakes from the ramekins. Spread the frosting over the tops and decorate with additional Christmas sprinkles.
