- Butter- You can use salted or unsalted butter for this recipe.
- Oil- The vegetable oil will help give these brownies an extra chewy texture.
- Granulated sugar & brown sugar- We are using a combination of sugars to really elevate both the flavors as well as the texture.
- Egg- Make sure it is at room temperature.
- Vanilla extract- This will help deepen the flavor of our brownies even more.
- Salt- Always add a little salt to your baked goods to help balance out the sweetness of the dessert.
- Flour – All purpose flour works great for this recipe.
- Cocoa powder- Make sure you are using high-quality unsweetened cocoa powder for this recipe. It will help the brownies taste even better.
- Semi-sweet chocolate chips– The semi-sweet chocolate chips are used to make the chocolate ganache topping so making sure to use high quality is a must here too. Feel free to also use dark chocolate instead if you prefer.
- Heavy cream – The heavy cream is also used to make the homemade version of the ganache that goes on top of our brownies.
- Mini rainbow sprinkles – I used the rainbow chips which are made with chocolate in the center but if you can’t find those feel free to use mini m&m as well! The colorful sprinkles on top are a must for this special treat because they really bring it together just like the Little Debbie’s cosmic brownie bites that you can find at your local grocery stores.
