Deliciously fudgy Birthday Brownies that are easy to make and the perfect birthday treat for anyone that does not want a cake!

Preheat your oven to 350 degrees F and spray with non stick spray and line a 8x8 baking dish with parchment paper and set aside.

Place the cream cheese, egg, egg yolk, cake mix, sugar, and vanilla in a medium bowl. Whisk until smooth, scraping down the sides of the bowl as needed. Mix in your rainbow sprinkles and set aside.

In a large bowl mix together your melted butter, vanilla extract, sugar and brown sugar until combined.

Mix in your eggs, one at a time. In a separate medium sized bowl whisk together your flour, cocoa powder, baking soda and salt and whisk together.

Slowly add your flour mixture to the wet ingredients and mix until fully combined and smooth.

Evenly spread half of your brownie batter into your prepared pan. Use an rubber spatula to spread the birthday layer over top of your brownie batter.

Place your remaining brownie batter over the birthday layer, then carefully spread it out. Use a butter knife to swirl the batter and the filling together slightly.

Bake your brownies for 30-35 minutes, or until a toothpick inserted into the center comes out just clean, it should have some crumbs. The center can still be a little jiggly.

Allow your brownies to cool to room temperature, slice and enjoy!
