When you think of birthday desserts, a cake is always the first thing that comes to mind, especially being a pastry school graduate, I love a pretty and decorated cake- especially one covered in rainbow sprinkles, SO FUN!

BUT- birthday brownies are also so fun, especially topped with a luscious vanilla frosting and rainbow sprinkles.

To make anyone’s birthday extra special you can also make these birthday cake cookies– these two combined are like the best homemade gifts ever!

These brownies don’t skimp on flavor or presentation – the frosting and sprinkles make them look like a bakery-style birthday confection! The inside of the brownies can be ooey and gooey or you can bake them a couple minutes longer to make them more on the cakey side.

If someone showed up at my house with these for my birthday I definitely wouldnt turn them down.

If you are a brownie lover like I am, definitely don’t miss out on these homemade cosmic brownies, these tangy cream cheese brownies, or these super rich triple chocolate brownies!

Make the frosting: While the brownies are cooling, make the vanilla frosting. Slather the frosting all over the cooled brownies and immediately top with sprinkles.

If you wait too long the frosten will harden and the sprinkles won’t stick, so make sure you have your sprinkles ready!
