How to Serve Ultimate Slutty Brownies
Ultimate Slutty Brownies are best served warm or at room temperature. You can enjoy them on their own, or pair them with a scoop of vanilla ice cream for a delightful dessert. For extra flair, drizzle with chocolate or caramel sauce!
How to Store Ultimate Slutty Brownies
Store your Ultimate Slutty Brownies in an airtight container at room temperature for up to 4-5 days. If you want them to last longer, you can freeze them. Wrap the brownies tightly in plastic wrap and place them in a freezer-safe container. They will keep well for up to 2-3 months in the freezer.
Tips to Make Ultimate Slutty Brownies
- Make sure to use softened butter for the cookie layer to create a creamy texture.
- Press the cookie layer down firmly to ensure it holds up under the weight of the Oreos and brownie batter.
- Allow the brownies to cool completely before cutting; this will help them set and make slicing easier.
Variation
If you want to switch things up, try using different types of cookies in place of the Oreos. Thin Mints or chocolate chip cookies also work great as tasty alternatives!
