You can! Talk about a huge time saver! If you’re wanting to make these brownies from scratch but realize you don’t have all the ingredients, don’t fret.

You can easily substitute out the steps for making the base and just use a brownie mix instead.

Just skip the first four steps to the recipe below and follow the directions on the brownie mix box. It’s as simple as that! 

The beauty of this Reese’s brownie recipe is it is able to adapt to your needs!

Are brownies better with oil or butter?

It all really depends on what type of brownies you’re wanting to have. While using either option for taste is fine, the addition of oil will give your brownies a more dense texture and appearance.

While using butter will give them a little bit more “fluff” and appear a bit lighter. 

The choice is ultimately up to you on what texture you prefer for your brownies.

How do you make chewy brownies not cakey?

I think we can all agree that there’s just something delicious about having a nice, chewy brownie. But there is a little trick to keep in mind if you’re wanting to make them chewy and not cakey.

In order to achieve that consistency, you need to be using granulated sugar and not brown sugar in your batter.

But don’t worry, this recipe has already taken that into consideration and it’s set up and ready to be made the perfect way to get chewy brownies every single time. 


How do you keep brownies moist?

Storing brownies in a sealed container with a lid or a sealable bag is the easiest way to keep them moist.

The air is going to be your enemy is making your brownies dry out.  And if you happen to notice that your brownies are starting to get a little dried out.

The easiest way to bring them back to having a bit of moisture is to put them in the microwave for a couple of seconds.

The heat (just a little bit) will be able to have them soften up a bit and have them bounce back to being moist in no time at all.  

Variations to Peanut Butter Cup Brownies 

As you can tell, these Reese’s Brownies are super simple to make. But, you can also branch out and use this batter mixture as a base for other added candy ingredients as well.
