Tips For Making The Best Cosmic Brownies
- Bake brownies in a light metal pan. (I use a stainless steel 9×13 pan.) Glass will take longer to bake and may dry your brownies out.
- Don’t over bake your brownies! You want them to be fudgy, not dry.
- If you want clean cuts you can run your knife under hot water and wipe it between each slice.








Can I Use Milk Chocolate Chips For My Ganache?
Yes, you can, but know that milk chocolate chips contain lower cocoa solids so you need to do a different ratio of chocolate chips to heavy whipping cream. I will include both options in the recipe card. I actually prefer using milk chocolate chips for my ganache, but I know that might be too sweet for some.

Ingredients
Method
- Preheat oven to 350℉ and grease/line a 9×13 metal pan with parchment paper.
- In a small bowl add flour, cornstarch, and salt. Mix until combined and set aside.
- In a separate mixing bowl add melted butter and cocoa powder and whisk until combined.
- Next add sugar, brown sugar, and vanilla and whisk until smooth.
- Whisk in the eggs and egg yolk one at a time.
- Then using a wooden spoon or spatula mix in the flour mixture. The batter will seem dry and thick. Don't worry the flour will mix in and this is what we want.
- Spread the batter evenly into your prepared pan and bake for 15-17 minutes. These are thin so be careful to not dry them out by overbaking them.
- Cool brownies in the pan on a cooling rack.
- The process will be the same for both the semi-sweet or milk chocolate ganaches. They just have slightly different ratios and note that if you want your ganache to set up more firm use semi-sweet. If you don't mind soft ganache and love the flavor of milk chocolate use the milk chocolate chips.
- Add chocolate chips to a small bowl.
- Heat heavy cream in a small saucepan to 180℉. If you don't have a thermometer heat until it's steaming and just starting to simmer on the edges. DON'T boil.
- Pour hot heavy cream over the chocolate chips and let sit for 1 minute.
- After 1 minute whisk the mixture together until smooth and creamy.
- Once the brownies are completely cool, pour ganache over the brownies and use an angled spatula to evenly spread.
- For candy coated chocolate chips you can either add them now or as the ganache sets up more. They will sit higher if you add as it cools.
- Put in the fridge for 1 hour for the ganache to set up.Slice and enjoy!*For the iconic line in the center of each brownie you can run a sharp knife down the center. Don't cut all the way through, just enough to add the line.









Could I substitute with honey or maple syrup? Or how would that work?
I’m sure you could, but you would have to adjust ratios and I haven’t tried that yet.
Made them tonight and they are delicious! What is the recommended way to store these brownies?
Glad you enjoyed them! I usually just leave them in an airtight container on the counter. They don’t last with our family more than 2-3 days lol!
Made them for the first time. They are delicious. There are just 2 of us. Do you think I could freeze them?
Glad you enjoyed them! They should definitely freeze well.
These brownies are amazing! So soft and taste like the real deal!!!
Glad you enjoyed them! <3
These brownies are so out of this world, they might attract some UFOs!
Do you sift the flour?
No
have you tried these in a little smaller pan? i have a 8 x 10 metal pan i would like to use.
I haven’t. They should work just watch the bake time.
they are super dry…what could I add to make them more like a brownie consistency?
