Nothing quite says “happy” like dessert. Furthermore, nothing says “birthday” nearly as well as Birthday Cake Oreos and confetti sprinkles. So, when I find myself thousands of miles across the country from most of my family, but I still need to make sure they are eating delicious baked goods on their birthday, that’s where Chocolate Chip Oreo Birthday Cake Bars come in. They are easy to make (we’re talking one bowl, 15-minute prep) and you can honestly throw in whatever mix-ins you have in your pantry already if you’re not being held to the whole “birthday” theme. If you don’t have Oreos or chocolate chips, throw in graham crackers and peanut butter chips. Sprinkle in some M&m’s if you’re feelin’ it. These bars seem to have more mix-ins than actual batter. I tend to do that a lot. I haven’t heard any complaints yet about an extremely low chocolate chip to batter ratio in any of my desserts. Let me know if I should stop with this kind of thing.

Birthday Cake Oreos are sweeter than the original flavor, but they are delicious. In my opinion, they taste like vanilla frosting and look like Funfetti cake. So yes, in conclusion, they are wonderful. Going along with the birthday theme of these bars, how could I not pour in tons of confetti sprinkles? It would be un-birthday like. Not only do sprinkles add a needed crunch to these warm, gooey bars, but they also make them look pretty. Sprinkles make everything look pretty. Sometimes I even sneak them into my morning yogurt to add some excitement to my day. (It’s the little things in life, right?) So, while I suppose they are an optional ingredient, if you have sprinkles on hand, I suggest you use them for these bars. I know I’ve never been disappointed by the addition of sprinkles to something, but I’m kind of my own breed of dessert alien at this point, so who knows.

Anyways, I hope you enjoy these Chocolate Chip Oreo Birthday Cake Bars. And if you don’t have a birthday to make them for, just make them for yourself. You might eat the whole pan in one day, but chocolate chips, Oreos, and sprinkles will often do that to a person. Don’t say I didn’t warn you.

Prep Time
15 min
Cook Time
22 min
  1. 1/2 cup (1 stick) of butter, melted
  2. 1 large egg
  3. 1 cup of light brown sugar, packed
  4. 1 tsp vanilla extract
  5. 1 cup of all-purpose flour
  6. 1 cup of semi-sweet chocolate chips
  7. 18 Birthday Cake Oreos, roughly chopped and divided
  8. 1/2 cup of confetti sprinkles (optional)
  1. Heat your oven to 350° F and line an 8"x 8" baking pan with aluminum foil. Spray the foil with nonstick cooking spray and set aside.
  2. In a microwave safe bowl, melt the butter. Be sure to wait a minute or two after melting the butter so you don't accidentally cook the egg. Combine the butter and egg in the mixing bowl, and then add in the brown sugar, vanilla extract, and flour. Stir well to combine. Then, fold in the chocolate chips, about 2/3 of the crushed up Oreos and the sprinkles. Mix until just combined.
  3. Pour the batter into the prepared baking pan, spreading it evenly to fill up the pan. Press the remaining Oreos to the top of the batter. If you would also like to sprinkle on some extra chocolate chips and sprinkles, feel free to do this as well.
  4. Bake the bars for about 22 minutes, or until the edges are slightly golden brown and a toothpick comes out clean. Cool the bars for about 30 minutes until cutting and serving.
  5. Enjoy!
