How to make the best fudge brownies

I live by boxed brownie mix! Honestly it's the only store bought mix I will never stop buying. Each time I need a little chocolate pick me up, the box of Duncan Hines brownie mix will always be there to comfort me. 
Every time I do use the mix, I try to find ways to change it. Either by adding chocolate chips, peanut butter, and even cookie dough. This time I did something way different, and this time the brownies stayed fudgey for a whole 4 days. Here's what I did:

Preheat oven to 350 degrees
As directed on the back of the Duncan Hines box you'll need: 
2 eggs
2/3 cups oil
1/4 cup water

But this is what I did differently...forget that 1/4 cup water. I saw I still had some brewed coffee from earlier in the day, so I thought why not. So I replaced the water in the recipe with leftover coffee. We all like to recycle, right?

Mix all the ingredients together and pour into a baking dish. Now with the batter in the baking dish, take some hot fudge from the jar or the Hershey's syrup, and drizzle on the batter. You can make a design like the one I did, or swirl it as you wish.

Bake for 30 minutes. Set a timer, mine actually came out perfectly after 30 minutes.

Let cool. Then cut anyway you want. I always cut them in tiny squares. It makes me feel like I can eat as many as I want since they're small portions.

I swear these were possibly the best brownies I've made in a while, and I make some pretty amazing brownies. They stayed moist, and unbelievably fudgey for days. I couldn't stop eating them during the weekend cause they never got stale or hard. 

Next time, I think I might try using caramel sauce instead of chocolate sauce. We'll see how that goes. 

If you try this recipe, let me know if you had the same results as I did, and if you added anything extra!

Happy Baking xo
