Our easy Jiffy corn muffins with sour cream recipe and jalapenos (optional) recipe tastes homemade because they turn out super moist. They are the all time best side dish to serve with our 5 Ingredient Crockpot Chili and always a family favorite.

Ok so for years I have made this Jiffy Mexican Cornbread but wanted to change it up a little bit and tweak the ingredients used on the box to make each bite as tender and moist as possible. After a few rounds of experimenting I made the BEST version ever and wanted to share how to make them with all of you.
Ok so when baking you may have figured out that adding a bit more fat into the mix makes your end result more fluffy and moist, same goes for these. Instead of just adding milk and egg (as directed on the box) you should add some sour cream!
With that said go for the real stuff, not light or low fat (that would defeat the whole purpose friends). Going a bit further, when adding the milk itself it is best to use vitamin D or at least 2%. Once again, more fat = moister and more flavorful.

Ingredient Notes
Milk should be whole or at least 2% to make them as moist as possible. You could use a dairy free alternative though I would suggest plain cashew milk in that case as it is the thickest and creamiest.
Your large eggs should be left out for a bit so they are closer to room temperature and whisked before adding for the ideal fluffy texture.
Sour cream is added to make them ultra moist. Plain Greek yogurt would be a good substitute if that is all you have on hand or just prefer this ingredient instead. It is also a great alternative if you need them to be dairy free you can use Silk brand or a lactose free version. I’ve done this to make our Jiffy Tamale Pie.
The main star of the show is a few boxes of Jiffy corn muffin mix. In order to make 12 muffins you are going to want 2. You could easily half this recipe if you only wanted to make 6 for sure. You’d just cut everything in half but leave the bake time the same.
How do you make Jiffy corn muffin mix from scratch?
Once you make this you may never buy those little white and blue boxes at the store. To make things easier you can gather all the ingredients listed below and combine into sandwich baggies to store in the pantry. Then when ready to make just combine with 1 large egg, and 1/3 cup milk to make the batter. Adding 2 Tbsp melted butter or sour cream makes them richer.
- 2/3 cup all purpose flour
- 1/2 cup yellow cornmeal
- 3 Tbsp. sugar
- 1 Tbsp. baking powder
- 1/4 tsp. salt
One year when I was forgetful and didn’t buy enough boxes to make these and our Jiffy corn casserole with cream cheese I had to make from scratch and it literally tasted the same so I have done it this way a few other times since then.
Can you add cheese?
Once again, this is optional but for me I grew up in a house that ALWAYS had a lot of cheese. Maybe that is the German side of my family speaking but everything is better with it! In this case since I wanted a bit more heat I used pepper Jack but shredded cheddar would work too if you prefer that variety.

Jiffy Corn Muffin Mix Add-ins
Let’s take it even another step further because I love to use a boxed mix and making it taste like homemade with this and that. I tried adding roasted jalapenos into other sides to add more flavor and a bit of heat and that worked well so why not with these??!!
Now the key to this is like with our Hush Puppies with Jiffy Mix I will add them diced inside the batter with 1 slice on the top. You can mess around with this combo depending on how spicy you may want them to be – or leave out entirely if you want to keep them as is and mild.
How Long to Bake Jiffy Corn Muffins with Sour Cream
Now you don’t want to cook these too long because you want them to be as moist and melt in your mouth as possible. With that said keep a close eye on them by minute 15 thru the oven window. If the middle doesn’t look quite done give it another 2 minutes.
How do you know when they are done?
In order to get the ideal texture you should check in 2 ways. When the top is lightly browned touch in the center gently with your finger. If it bounces back they are done, if it sinks it needs another 2 minutes and then check again. With a toothpick insert in the center. You want wet crumbs attached, not dry or with wet batter.

Other ways to make Jiffy corn muffin mix better
It is not just for muffins either y’all. A great tweak during the holidays is to make this version of our Cornbread Dressing with Jiffy Mix. You can add heat to this as well if you like, prepare in a casserole dish like we did or stuff your turkey with it. Both will blow your mind!












Ii look forward to trying this recipe. I love the recipes you share on YouTube. They are simple and easy to make!
