Pre-heat oven to 450 F.

Prepare 2 - 3 " mini cake pans by spraying them with oil and dusting with flour. Don't skip the flour or the cakes will stick.

In a medium microwave safe bowl, melt butter for 30 seconds.

Add white chocolate chips and let sit for a minute.

Stir chocolate chips and butter together until white chocolate chips are melted. If the chocolate chips do not melt then microwave for 5 second intervals then stir until they are all melted into the butter.

Add vanilla, food coloring, sugar and salt to the butter mixture and stir.

Add egg and egg yolk and stir again.

Sprinkle flour over the top of batter and mix it in well.

Pour into prepared mini cake pans and bake for 8:30-9 minutes. In my experience 10 minutes will be too long but all ovens vary slightly. The sides will fell like they are starting to set but the middle will feel runny.

Remove from the oven and let them cool for 1 minute before gently flipping them over onto the serving plate.

Enjoy!
