These easy Jiffy Jalapeño Cheddar Cornbread Muffins are the perfect combination of sweet, savory, and slightly spicy.

Ingredients

Substitutions
Milk: Whole milk will give you a moister cornbread, but reduced-fat milk will work as well! I've also tested buttermilk in this recipe. Use ½ cup per box instead of ⅓ cup. The acidity of the buttermilk may curdle your eggs, so I like to mix the buttermilk in first, then the eggs. Buttermilk makes the muffins more tender.
Cheddar Cheese: I like to use sharp cheddar so the cheese flavor doesn't get lost in the cornbread. You can also use Gouda or pepper jack cheese.
Jalapeño: Two unseeded jalapeños will give you a light jalapeño taste. These muffins are very mild and may have little to no spice. If you want some spice, leave the seeds in the jalapeños. The more seeds you leave, the more heat you'll get.
How to Make Jiffy Jalapeño Cornbread

Mix
In a mixing bowl, combine all of the ingredients until the batter is evenly mixed. Be careful not to overmix the batter.

Fill Tin
Spray a standard 12-cup muffin tin with nonstick cooking spray. Divide the batter evenly among the muffin cups, filling all 12 cups. Top each one with a jalapeño slice.

Bake
Bake for 17-20 minutes, or until the muffins are fluffy and golden brown and cooked through. Let them cool slightly before serving warm.
Tips
Spice: Using two unseeded jalapeños will give you a mild flavor with little to no heat. For more spice, leave the seeds in the jalapeños.
Don't overmix: Stir the batter just until the ingredients are evenly combined. Overmixing can affect the texture of the muffins.
Use fresh jalapeños: I prefer using fresh jalapeños because I like the color and appearance they add to the muffins.
How to Store Leftovers
Place leftover cornbread in an airtight container or a large ziplock bag. Store at room temperature for about two days or in the fridge for a week.
You can also freeze them for up to 3 months. To defrost, thaw in the fridge overnight or on the counter for 1-2 hours. These muffins are also good at room temperature, so you don't need to reheat them before serving.

Sean says
I always do mine slightly different, I use pepper jack cheese and I add a little sour cream. The pepper jack will give the muffins a touch more heat if you like that kinda thing. Other than that this recipe has been a huge hit at family gatherings, chili night or just a BBQ at a friends. I would definitely use buttermilk instead of regular milk, helps keep the cornbread nice and moist.
Keithk says
My wife makes cowboy candy with jalapenos and I use that instead of regular jalapenos. It added a sweetness that was unbelievable. Thank you for sharing your recipe.

Could not taste the cheese at all.
Amy says
Did you seed your jalapeños first or leave in?
Megan says
Hi Amy! I didn't include the seeds when making the muffins, and they had a mild spice. If you want these really spicey, include the seeds from one or two of the jalapenos.
Beth says
Can I use regular milk if I don't have buttermilk?

Yes, you don't need to alter the recipe at all, just use 1 cup of regular milk.
