The Origins of Slutty Brownies
The exact origin of Slutty Brownies is unknown, but they rose to fame around 2011, when a food blogger, The Londoner, popularized the name. The playful and slightly controversial title comes from their outrageously indulgent nature.
Other sources suggest that layered brownies existed earlier under names like Brookies (brownie + cookie) or Oreo-stuffed brownies, but the viral marketing of “Slutty Brownies” solidified their popularity in food culture.

Common Mistakes and How to Fix Them: Troubleshooting Slutty Brownies
Even the most experienced bakers can run into problems when making Slutty Brownies. From undercooked centers to dry edges, small mistakes can lead to less-than-perfect results. Below, we’ll cover common baking issues and how to fix them, so your Slutty Brownies turn out rich, gooey, and perfectly layered every time.
1. Brownies Are Undercooked in the Middle
The Problem:
After baking, you cut into your brownies and find the center is too gooey or raw.
Why It Happens:
- Oven temperature was too high, causing the edges to cook faster than the middle.
- The pan was too small, making the layers too thick to cook evenly.
- You removed them from the oven too soon.
How to Fix It:
- Use an oven thermometer to ensure your oven is actually at 350°F (175°C). Many home ovens run hotter or cooler than the display indicates.
- Bake in the correct pan size—a 9×9-inch pan works best. If using a smaller pan, bake 5-10 minutes longer.
- Cover the pan loosely with foil and bake for an extra 5-10 minutes if the center is still raw.
- Use the toothpick test—insert a toothpick into the center. If it comes out with wet batter, bake longer. If it has a few moist crumbs, they’re done!
2. Brownies Are Too Dry or Crumbly
The Problem:
Instead of a gooey, fudgy texture, your brownies turn out dry, crumbly, or cake-like.
Why It Happens:
- You overbaked them.
- Too much flour was used, making them dense.
- Not enough butter or fat in the batter.
- Overmixing the brownie batter, incorporating too much air.
How to Fix It:
- Set a timer and check brownies 5 minutes before the recommended baking time ends
- Measure ingredients correctly—use a kitchen scale for precise measurements, especially for flour.
- Use melted butter instead of oil, as butter adds moisture and richness.
- Mix just until combined—overmixing leads to drier brownies.
3. The Layers Didn’t Bake Evenly or Merged Together
The Problem:
Instead of having three distinct layers, your cookie dough, Oreos, and brownie batter blended together.
Why It Happens:
- The cookie dough layer was too warm and spread too much.
- The brownie batter was too runny, causing it to sink into the cookie dough.
- You pressed the Oreos down too hard, pushing them into the cookie layer.
How to Fix It:
- Chill the cookie dough for 10-15 minutes before spreading it in the pan.
- Make a thick brownie batter—if it’s too runny, add an extra tablespoon of cocoa powder
- Gently place the Oreos on top without pressing them too deeply.
4. Brownies Stuck to the Pan
The Problem:
You try to lift your brownies, but they stick to the pan, breaking apart.
Why It Happens:
- You didn’t grease or line the pan properly.
- The brownies weren’t fully cooled before cutting.
How to Fix It:
- Always use parchment paper, leaving an overhang for easy lifting.
- If you forgot parchment paper, grease the pan with butter AND flour.
- Let the brownies cool completely before cutting—this takes about 1 hour.
5. The Brownies Fell Apart When Slicing
The Problem:
Your brownies crumble or fall apart when you try to slice them.
Why It Happens:
- You cut them while they were too warm.
- You used a dull knife, dragging through the layers.
How to Fix It:
- Use a sharp knife and clean it between cuts for cleaner slices.
- Chill the brownies in the fridge for 30 minutes before slicing.
