Heeeeey, you! Happy Wednesday!

First thing’s first – I’m freezing! I know that many of you are also in the same predicament, but still… it’s freakin’ cold! I am SO ovah this polar vortex thingamajig.

Yesterday was the first day I left the house in 3 days, and it was only because I had to – we were having Christmas lunch at my mom’s, aaaaand a girl’s gotta eat, you know what I mean?! 

P.S. I am Macedonian Orthodox and we celebrate Christmas on the 7th of January. 

So. These Skinny Brownies and my Banana Foster No-Bake Cheesecake also made it to her house. {And two bottles of wine plus a case of beer.} The brownies and cheesecake were devoured waaaaay before anyone even reached for the soup-and-salad stuff.

This is the kind of brownie you eat when it’s the first week of the new year. Even the second… They say that the NY Diet Resolution is alive and well for about the first two weeks of the year… thereafter, most people go back to their “normal” ways. Thank Goodness!!

Don’t get me wrong – I DO LOVE eating my Maple Nut Granola every day, but I’m sorta itching for some Bacon and Eggs - that’s some really, reaaaaally good stuff!

Pillsbury Classic Fudge Brownie Mix Skinny Brownies

Many moons ago, one of my aunts owned a bread bakery. She had a couple of baking secrets that she shared with me and one of those secrets was using carbonated drinks with cake mixes. She only sold bread and savory pastries in her bakery, but at home she rocked the cake mixes!

I had this Pillsbury Brownie Mix sitting up on one of my pantry shelves and I decided to use my aunt’s suggestion. So I poured the Sprite into the brownie mix, gave it a whisk or two, and popped it in the oven. What came out of the oven is what I least expected – tall, soft, springy, fudgy, deeeeelicious brownies! I was incredibly excited about the results, thus I went back to buy some more mixes and share the recipe with you, of course!

    I will have to try to the Sprite version. I have used Diet Cherry Cola and it works quite well with the chocolate (without much of a cherry taste — just that little something).

    I cannot wait to try this!
    On a side note I feel bad for you guys in the Polar Vortex, as we here in Australia swelter through 109 degrees today!

    Now this is my kind of baking… a must try recipe. :)

    Would love to try this and I have a question. The brownie mix you use…is the mix the kind you just add water to, or do you use the kind of mix you also add eggs to but omit the eggs and add sprite? Hope that makes sense :)

      Hi Anne! Yes, this brownie mix is the one that asks for eggs and oil, but instead of all that jazz, just pour in some sprite and pop it in the oven. :-) The brownie mix for this is also a small one – 10-ounces. If you are going to use the bigger boxes, you would need to add more sprite. Hope that helps!!

    Would Diet Sprite work?

      Hi! Yes, Diet Sprite works, too. That’s even less calories! :-D

    This is a genius recipe! I had no idea Sprite could make brownies. I haven’t left the house in three day either and it’s gonna be at least one more. I don’t do polar vortex ;)

    I use club soda in mixes. Same results but NO EXTRA CALORIES!

    • Katerina Petrovska January 8, 2014 at 9:59 AM - Reply

      Yep! I could have done it with club soda, but I wanted the extra bit of flavor and that’s why I went with Sprite. :-)
