For the Birthday Cake Frosting:

Step-by-Step Cooking Instructions

Here’s a step-by-step guide to making these delicious Birthday Cake Oreo Fudge Brownies.

Step 1: Prepare the Brownie Batter

1. Preheat the oven to 350°F (175°C). Grease and line a 9x13-inch baking pan with parchment paper, leaving a bit of overhang on the sides for easy removal.
2. In a medium saucepan, melt the butter over medium heat. Once melted, remove from heat and stir in the sugar, cocoa powder, and salt until combined.
3. Add the vanilla extract and stir in the eggs, one at a time, making sure each egg is fully incorporated before adding the next.
4. Sift in the flour and gently fold it into the batter until just combined—be careful not to overmix.
5. Stir in the chocolate chips for extra fudginess.

Step 2: Layer the Birthday Cake Oreos

1. Pour half of the brownie batter into the prepared pan and spread it out evenly with a spatula.
2. Place the Birthday Cake Oreos on top of the batter in an even layer. You should be able to fit about 24 Oreos (a full package) into the pan.
3. Pour the remaining brownie batter over the Oreos and spread it out carefully to cover them completely.

Step 3: Bake the Brownies

1. Place the brownies in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted into the center comes out mostly clean with a few fudgy crumbs (not wet batter).
2. Once baked, remove the brownies from the oven and allow them to cool completely in the pan.

Step 4: Prepare the Birthday Cake Frosting

1. While the brownies are cooling, make the birthday cake frosting. In a large mixing bowl, beat the butter and shortening together until smooth and creamy.
2. Gradually add the powdered sugar, about ½ cup at a time, mixing on low speed to prevent it from flying everywhere.
3. Add the vanilla extract and optional almond extract for that classic birthday cake flavor. Then, slowly add milk, one tablespoon at a time, until the frosting reaches a spreadable consistency.
4. Once the frosting is smooth and creamy, set it aside.

Step 5: Frost and Decorate the Brownies

1. Once the brownies are completely cooled, spread the birthday cake frosting over the top in an even layer.
2. Sprinkle the frosting generously with colorful sprinkles to give the brownies that birthday cake look.
3. Place the pan in the fridge for about 30 minutes to set the frosting before cutting the brownies into squares.

Common Mistakes to Avoid

To make sure your Birthday Cake Oreo Fudge Brownies come out perfect, avoid these common mistakes:

• Not Cooling the Brownies Before Frosting: Always wait for the brownies to cool completely before frosting them, or the frosting will melt and become a mess.
• Overbaking the Brownies: Brownies are best when they’re fudgy and moist, so don’t overbake them. They will continue to firm up as they cool, so aim for slightly underdone in the center.
• Overmixing the Batter: Mix the brownie batter until just combined to avoid a tough texture. Overmixing can cause the brownies to become dense and less fudgy.

Serving and Presentation Tips

Here are a few tips to make your brownies look and taste even better:

1. Cut with a Hot Knife: To get clean, sharp edges on your brownies, dip your knife in hot water, wipe it off, and then slice. Repeat this process between each cut.
2. Extra Oreos on Top: If you want to go the extra mile, crumble some extra Birthday Cake Oreos on top of the frosting for added crunch and decoration.
3. Serve with Ice Cream: For a truly decadent dessert, serve the brownies with a scoop of vanilla ice cream on the side and drizzle with hot fudge sauce.

Birthday Cake Oreo Fudge Brownie Recipe Tips

Here are some additional tips to help you make the best brownies possible:

• Use Room Temperature Eggs: Room temperature eggs blend more smoothly into the batter, resulting in a better texture for your brownies.
• Don’t Skip the Shortening: The addition of vegetable shortening in the frosting gives it extra stability and that classic, light birthday cake frosting texture.
• Chill for Neater Slices: If you want super clean brownie slices, chill the brownies in the fridge for at least an hour before cutting.
