Diet Coke Brownies – A low fat brownie made with Diet Coke. For an added treat, I stirred in some butterscotch candy.
Brownies are by far my favorite dessert out there. They are just so darn good, and there are a million ways to mix them up and make them even better! Adding Girl Scout Cookies and making Thin Mint Brownies are just one the ways.
But let’s face it, eating brownies often is not good for you. So sometimes you need to find a way to make them just a little bit better for you.

What Are Diet Coke Brownies
This recipe has been around for years. Basically you cake a box brownie mix or even cake mix, and use a can of soda in place of any oil, eggs, or water called for in the recipe. It bakes up like a brownie, muffin or cake (depending on the mix you used), but there are obviously less calories and fat in them.
You can really use any can of soda. People often use a vanilla cake with a lemon lime soda or other fun combinations. Here I am using diet coke, which is calorie free, so it isn’t adding anything but the calories in the mix to the dessert.
How To Make Diet Coke Brownies
- In a bowl mix together the brownie mix and a can of diet coke until everything is incorporated. Do this carefully or the diet coke will foam up and make a mess.
- I had leftover Easter candy, so I added a few chocolate eggs to the mix. But you can skip that or mix in whatever else you like, just know that it will add calories and fat.
- Pour into your prepared 8 inch baking dish and bake.
- Let the brownies cool completely before slicing to serve.
Diet Coke Brownies have a very cake like consistency. They are extremely moist. So much so, that they are difficult to cut. I recommend refrigerating them to get them more solid, before slicing.
Without the added candy they are only 115 calories a serving, so they are much lower in calories than a traditional brownie.

How creative! I can’t believe they look so decadent and are so not!
Erin says
So I tried making this last night, using root beer instead, but the batter was more of a cake batter consistency so all the chips sunk to the bottom and it took almost twice as long to cook. I used 12 oz of root beer idk what went wrong. But they still tasted wonderful!
Erin says
That is weird, my batter was super thick!
Kimberly says
