My butter swim cornbread is exactly what it sounds like! You melt a full stick of butter in the pan, pour the batter right on top, and let it bake into the most golden, crispy-edged, tender cornbread you’ve ever made. This gluten-free version is loaded with sharp cheddar and pickled jalapeños and comes together in one bowl. It’s the best!

That buttery, cheesy crumb is everything. This gluten-free jalapeño cheddar butter swim cornbread is one of those recipes I’ll be making on repeat.

A Note From Kristen

The butter swim technique works so well with gluten-free flour because the butter compensates for the slightly drier texture you can sometimes get. The result is rich, moist, and has that crispy buttery bottom that makes you want to eat it straight from the pan! The pickled jalapeños are my favorite part. They add subtle heat and a little tang that fresh jalapeños just don’t give you. You guys loved my butter swim biscuits, so I knew what just had to come next. Happy eating!

Key Ingredient Notes

A few quick notes on the ingredients that matter most. Find the full ingredient list and instructions in the recipe card below.

  • Gluten-Free All-Purpose Flour: Use a blend that contains xanthan gum. I recommend Bob’s Red Mill 1-to-1 or King Arthur Measure for Measure. A flour blend without xanthan gum will give you a crumbly result. As a side note, if you aren’t gluten-free, regular all-purpose flour works in place of a gluten-free blend.
  • Pickled Jalapeños: These are the move over fresh jalapeños here. They bring heat plus a vinegary tang that balances the richness of the butter and cheese beautifully. Find them in a jar near the canned peppers at most grocery stores.
  • Buttermilk: If you don’t have buttermilk on hand, combine 1½ cups milk (any kind – dairy or non-dairy) with 1½ tablespoons lemon juice or apple cider vinegar and let it sit for 5 minutes.

My Favorite Ways to Serve Butter Swim Cornbread

  • Serve warm straight from the pan with extra butter (my fave!).
  • Pair with a big bowl of veggie chili, corn chowder, or bean soup.
  • Serve alongside scrambled eggs for a savory breakfast.
  • Top a square with a drizzle of hot honey for a sweet and spicy combo.
  • Crumble leftovers over a salad or grain bowl for crunch.

Kristen’s Top Tips

  • Do not stir the batter into the butter when you pour it in. Just let it sit on top and the oven does the work.
  • Let the batter rest for the full 5 minutes before folding in the cheese and jalapeños. This gives the gluten-free flour time to hydrate.
  • Score the top before baking so your squares come out clean and even.
  • Cool for at least 10 minutes before cutting. It firms up as it cools and slices much cleaner.
  • This butter swim cornbread is mild overall. The pickled jalapeños bring more tang and subtle sweetness than heat. If you want a spicier version, add one finely chopped serrano or habanero to the batter.
