Recipe Notes:

  • Make cutting the brownies easier by lining your baking pan with foil, allowing some of the foil to hang over the edges, which will help you to lift them out of the pan once cooled for you to cut them on a large cutting board. Peel away the foil before cutting them. 
  • Use high-quality cocoa for the best results. 
  • Don’t over-mix the batter otherwise, the brownies will become dense. 
  • Be patient when making the ganache as you don’t want to burn the chocolate. 
  • Chill the brownies for 2 hours once the ganache has been added so it sets enough for the brownies to be cut into clean lines. 
What variations can I make to this recipe?

– You can use a fudge brownie mix for this recipe instead of making the brownie batter from scratch.  
– Chopped peanuts (raw or roasted) added to these brownies would also offer a delicious addition of crunch. 

– Use gluten-free flour in this recipe for any dietary needs. 

I used a 9×9 inch baking pan to keep these brownies thinner like a Little Debbie but you can make your brownies thicker by using an 8×8 inch pan instead. –

Can I freeze these brownies?

To freeze your brownies, ensure they have completely cooled down first, and then wrap them in plastic wrap or foil to be stored in an airtight container. I like cutting my brownies and then wrapping them individually, so I don’t have to defrost an entire tray just to eat a few. 


You can store these brownies in your freezer for 2-3 months. Defrost them overnight in the refrigerator and then add fresh ganache with rainbow chocolate chips before serving.
