It sounds like a science experiment to add soda to a brownie mix, but it works. I don’t who created this recipe, or how it works, but you get a tasty pan of brownies for which the nutrition information is not much more than a serving of the mix, as quoted on the brownie box.
Here’s the recipe for the magic:
- 1 box of brownie mix
- A 1-egg serving of liquid eggs, per package information
- Diet cola
For the brownie mix, I tend to use the Ghirardelli dark chocolate chunk, but any brand and flavor will do. The eggs are usually 1/4 or 1/3 of a cup, depending on the brand. I add the eggs to the mix, and the I add enough soda (usually Coke Zero for me) to make the same brownie mix consistency you get with the traditional ingredients (usually this is at least 2/3 of a cup of soda).
Bake the brownies at the temperature listed on the box, cool, and cut. There may be a slight cola taste, but if you get the right mix, the chocolate flavor is stronger.
BONUS: This also works for cake. I have made yellow cake in a 13×9 pan with a diet lemon-lime soda rather than cola. It makes a moist cake.
