Ingredients List for Birthday Cake Oreo Fudge Brownies
Here’s what you’ll need to make these decadent brownies:
For the Brownies:
- 1 cup unsalted butter, melted

- 1 cup brown sugar, packed
- 4 large eggs, room temperature
- 2 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1 cup unsweetened cocoa powder

For the Birthday Cake Frosting:
- ½ cup unsalted butter, softened
- 4 oz cream cheese, softened
- 3-4 cups powdered sugar
- 2 teaspoon vanilla extract
- 2-3 tablespoon heavy cream (to thin as needed)
- ¼ cup rainbow sprinkles (plus extra for topping)
Optional Toppings:
- 6–8 additional Birthday Cake Oreos, roughly chopped (for garnish)
- More sprinkles for decoration
Substitutions and Variations
Feel free to experiment with different variations to make these brownies your own:
- Gluten-Free Option: Substitute the all-purpose flour with a gluten-free flour blend that works 1:1 in recipes to make gluten-free brownies.
- Dairy-Free Version: Use vegan butter and dairy-free cream cheese alternatives, and substitute the heavy cream with coconut cream to make a dairy-free version.
- Different Oreo Flavors: Try other Oreo flavors like Golden Oreos, Peanut Butter Oreos, or even Double Stuf for an extra indulgent twist.
- Extra Chocolatey: Stir in some mini chocolate chips into the brownie batter for a double chocolate effect.
Step-by-Step Cooking Instructions
How to Make the Fudge Brownies:
- Preheat the oven and prepare the pan: Preheat your oven to 350°F (175°C). Line a 9x13-inch baking dish with parchment paper, leaving a bit of overhang for easy removal later. Grease the parchment paper lightly.
- Melt the butter and mix with sugars: In a large microwave-safe bowl, melt the butter, then whisk in the granulated sugar and brown sugar until combined and smooth.
- Add eggs and vanilla: Whisk in the eggs, one at a time, ensuring they are fully incorporated. Stir in the vanilla extract.
- Mix in dry ingredients: In a separate bowl, whisk together the flour, cocoa powder, salt, and baking powder. Gradually add the dry mixture to the wet ingredients, stirring until just combined. Be careful not to overmix.
- Add chocolate chips: Stir in the chocolate chips to the brownie batter for extra fudgy goodness.
- Layer the Oreos: Pour half of the brownie batter into the prepared baking dish and spread it out evenly. Place the chopped Birthday Cake Oreos evenly on top of the batter, then pour the remaining brownie batter over the Oreos, smoothing it out with a spatula.
- Bake the brownies: Bake the brownies for 30–35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Be careful not to overbake, as brownies continue to firm up as they cool.
- Cool the brownies: Allow the brownies to cool completely in the pan before frosting.
How to Make the Birthday Cake Frosting:
- Beat butter and cream cheese: In a large mixing bowl, beat the softened butter and cream cheese together until smooth and fluffy, about 2–3 minutes.
- Add powdered sugar and vanilla: Gradually add the powdered sugar, one cup at a time, beating on low speed to avoid a sugar cloud. Add the vanilla extract and continue to beat until smooth.
- Adjust consistency: Add heavy cream, 1 tablespoon at a time, until you reach a smooth, spreadable consistency. The frosting should be thick but spreadable.
- Mix in sprinkles: Stir in the rainbow sprinkles for that classic birthday cake flair.
Assemble the Birthday Cake Oreo Fudge Brownies:
- Frost the brownies: Once the brownies are completely cooled, spread a generous layer of birthday cake frosting over the top. Use an offset spatula to smooth the frosting evenly.
- Garnish with Oreos and sprinkles: Decorate the frosted brownies with more chopped Birthday Cake Oreos and a handful of sprinkles for a festive look.
- Chill and slice: For clean, neat slices, refrigerate the brownies for 20–30 minutes to set the frosting. Then, lift the brownies out of the pan using the parchment paper overhang and slice into squares.
Common Mistakes to Avoid
- Overmixing the Batter: Once you add the dry ingredients to the wet, mix just until combined. Overmixing can lead to tough, dense brownies.
- Overbaking: Be sure to keep a close eye on the brownies during the last few minutes of baking. You want them to be fudgy and moist, so remove them from the oven when a toothpick comes out with a few moist crumbs.
- Not Cooling the Brownies: Allow the brownies to cool completely before frosting, or the frosting may melt and become runny.
Serving and Presentation Tips
These brownies are not only delicious but visually stunning when dressed up with colorful sprinkles and Oreos. Here’s how to serve them for maximum impact:
How to Serve Birthday Cake Oreo Fudge Brownies:
- Slice with a hot knife: For clean cuts, dip your knife in hot water, wipe it dry, and slice the brownies. Repeat this process between cuts for neat squares.
- Serve chilled or at room temperature: These brownies taste great both chilled (for a firmer texture) or at room temperature (for a gooier texture). If chilled, allow them to sit out for 10–15 minutes before serving to soften slightly.
Presentation Ideas for Birthday Cake Oreo Fudge Brownies:
- Add Extra Drizzle: Drizzle melted white or dark chocolate over the top of the brownies for a gourmet touch.
- Oreo Tower: For a party presentation, stack Oreo cookies on top of the frosted brownies, building a little Oreo “tower” in the center for a fun effect.
- Sprinkle Explosion: Use extra rainbow sprinkles around the serving plate for a colorful, playful presentation.
Birthday Cake Oreo Fudge Brownies Recipe Tips
- Room Temperature Ingredients: Ensure the butter and eggs are at room temperature before mixing to create a smooth batter and evenly baked brownies.
- Make Ahead: These brownies are perfect for making ahead of time. You can bake the brownies a day in advance, frost them, and store them in the fridge until ready to serve.
- Storage: Store the brownies in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days. You can also freeze them for up to 3 months.
Frequently Asked Questions (FAQs)
Can I Freeze Birthday Cake Oreo Fudge Brownies?
Yes! You can freeze the brownies with or without the frosting. Wrap the brownies tightly in plastic wrap, then in aluminum foil, and freeze for up to 3 months. Thaw overnight in the fridge and add fresh sprinkles before serving for the best results.
Can I Use Store-Bought Frosting Instead?
Absolutely! If you're short on time, you can use store-bought vanilla frosting and stir in some sprinkles to create a birthday cake effect. Just keep in mind that homemade frosting adds a richer, creamier flavor.
What If I Can't Find Birthday Cake Oreos?
No worries! You can use regular Oreos or another Oreo flavor that you love. For the birthday cake flavor, you can even add a little extra vanilla extract and more sprinkles into the frosting.
