How to Cook Birthday Cake Oreo Fudge Brownies: A Step-by-Step Guide
- Prepare the Oven and Pan: Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking pan or line it with parchment paper, leaving a bit of overhang on the sides for easy removal later.
- Make the Brownie Batter:
- In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar until combined and smooth.
- Add the eggs one at a time, whisking well after each addition.
- Stir in the vanilla extract.
- In another bowl, sift together the flour, cocoa powder, baking powder, and salt.
- Gradually fold the dry ingredients into the wet ingredients, mixing until just combined. Be careful not to overmix, as this could result in tougher brownies.
- Layer the Birthday Cake Oreos:
- Pour half of the brownie batter into the prepared baking pan and spread it evenly.
- Arrange the Birthday Cake Oreos in a single layer on top of the brownie batter, pressing them down gently.
- Add the Remaining Brownie Batter:
- Spread the remaining brownie batter over the layer of Oreos, covering them completely.
- Bake the Brownies:
- Place the pan in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Be careful not to overbake, as you want these brownies to stay fudgy and moist.
- Prepare the Fudge Topping:
- While the brownies are baking, combine the sweetened condensed milk, chocolate chips, and heavy cream in a medium saucepan over low heat.
- Stir continuously until the chocolate chips are completely melted and the mixture is smooth and creamy.
- Remove from heat and stir in the vanilla extract.
- Add the Fudge Topping:
- Once the brownies are done baking, let them cool for about 10 minutes.
- Pour the fudge topping over the brownies and spread it out evenly.
- If desired, sprinkle some extra colorful sprinkles on top for a festive touch.
- Chill and Serve:
- Allow the brownies to cool completely at room temperature, then refrigerate for at least 2 hours to let the fudge topping set.
- Once set, use the parchment paper overhang to lift the brownies out of the pan.
- Cut into squares and serve.
Common Mistakes to Avoid
- Overmixing the Batter: Overmixing can make your brownies dense and tough. Mix just until the ingredients are combined.
- Overbaking: These brownies should be fudgy, so avoid baking them until they’re dry. Check for doneness by inserting a toothpick – it should come out with a few moist crumbs.
- Skipping the Chill Time: Letting the brownies chill helps the fudge topping to set, making them easier to cut and serve.
