Jalapeño Cheddar Almond Flour Cornbread — Low Carb, Gluten Free, 4.1g Net Carbs
/Classic cornbread with butter is one of those foods that makes a bowl of chili feel like a proper meal instead of just soup. This jalapeño cheddar almond flour cornbread does exactly that — without corn, without wheat flour, and with only 4.1g net carbs per slice.
What it does have: sharp cheddar distributed throughout the batter so every slice has cheese in every bite, finely diced jalapeños for a mild-to-moderate heat that builds rather than punches, Kerrygold butter and sour cream for richness, and almond flour that creates the same soft, slightly crumbly texture as traditional cornbread without the grain.
Eight ingredients. One bowl. 30 minutes. Twelve slices per batch that keep a week in the fridge or three months in the freezer — including as croutons, which is the best use of leftover cornbread you've probably never tried.

The Secret Ingredient That Makes This Taste Like Real Cornbread (Optional)
Almond flour doesn't taste like corn. That's the honest truth that most low carb cornbread recipes don't address — the texture can be there, the buttery richness can be there, but the actual corn flavor is missing because there is no corn.
One optional ingredient fixes this: sweet corn extract. A few drops (approximately 1 teaspoon) stirred into the batter adds a genuine, natural corn flavor to the almond flour without a single carb from actual corn. LorAnn Oils makes the most widely available version, found on Amazon and in specialty baking stores. Wholesome Yum — one of the most heavily trafficked low carb recipe sites — calls this their "secret ingredient" and describes the result as tasting like actual cornbread rather than a low carb approximation.
This ingredient is listed as optional because the cornbread is very good without it. But if you've made low carb cornbread before and found yourself thinking "it's missing something" — this is what was missing.
Where to find sweet corn extract — available on Amazon, at Michaels and JoAnn Fabric stores (in the baking section), and some specialty grocery stores. One small bottle lasts through many batches. Use 1 teaspoon per batch — it's concentrated and a little goes a long way. Do not use corn syrup or corn oil as substitutes — these add carbs and change the texture.
Ingredients
2½ cups Super Fine Blanched Almond Flour
2½ cups shredded sharp cheddar cheese — freshly shredded from a block (see note below)
2 jalapeños, finely diced, seeds removed — optional, see heat guide below
2 teaspoons baking powder
½ teaspoon salt
3 large eggs
½ cup full-fat sour cream
¼ cup Kerrygold unsalted grass-fed butter, melted
1 teaspoon sweet corn extract (optional — see section above)
The Jalapeño Question — How Much Heat, How to Adjust
Two jalapeños with seeds removed gives this cornbread a mild-to-moderate heat — noticeable warmth that builds through the piece without being aggressive. Here's how to dial it up or down:
No heat (mild version): omit the jalapeños entirely. The cheddar-butter-sour cream cornbread is excellent on its own — a cheesy, buttery, savory side that works for all ages and heat tolerances.
Mild heat: use 1 jalapeño, seeds removed. Subtle warmth in occasional bites.
Medium heat (the recipe as written): 2 jalapeños, seeds removed. Consistent warmth throughout, pairs well with chili.
Hot: 2-3 jalapeños with some or all seeds included. Seeds and the white membrane are where most of the capsaicin lives. Wear gloves when handling.
Extra hot: substitute 1 jalapeño with 1 serrano pepper (smaller, hotter). Or use pickled jalapeños — they add a tangy note alongside the heat.
Can I use canned jalapeños instead of fresh?
Yes — drain and pat dry canned sliced jalapeños and roughly chop them. Use about 3-4 tablespoons for the equivalent of 2 fresh jalapeños. Canned jalapeños are slightly more tender and tangier than fresh, which works well in this recipe. Make sure to pat them very dry — excess liquid from the can can make the batter wetter than intended.
Why Freshly Shredded Cheddar
Pre-shredded bagged cheddar is coated in anti-caking agents (potato starch, cellulose, or natamycin) that prevent it from melting smoothly into the batter. In a baked item like this, that coating creates drier, harder cheese pockets that don't fully integrate into the cornbread.
Freshly shredded cheddar from a block melts into the batter during baking and creates an evenly cheesy, cohesive cornbread throughout. The taste difference is also significant — block cheddar has more pronounced, sharper flavor than pre-shredded. Use sharp or extra-sharp cheddar for maximum cheddar presence. Tillamook, Cabot, or Kerrygold cheddar are all excellent block options.
Step-by-Step Instructions
Preheat. Oven to 350°F. Grease a 9x13 baking dish with butter or avocado oil cooking spray — get into the corners and up the sides.
Prep jalapeños. Finely dice the jalapeños, removing the seeds and white membrane for medium heat (keep some seeds for hotter). Set aside.
Shred the cheddar. Grate fresh cheddar from a block. Set aside.
Combine all ingredients in one bowl. Add the almond flour, shredded cheddar, diced jalapeños, baking powder, and salt to a large bowl. Whisk together briefly. Add the eggs, sour cream, melted butter, and sweet corn extract if using. Stir with a spatula or large spoon until all ingredients are combined — no dry pockets of almond flour remaining. The batter will be thick.
Transfer to baking dish. Pour the batter into the greased 9x13 baking dish. Use a spatula to spread it evenly to the corners — the batter is thick enough that it won't self-level.
Bake. 20-25 minutes at 350°F until the edges are lightly browned and a toothpick inserted in the center comes out clean. Check at 20 minutes — the baking time varies slightly depending on your oven and how thick the batter is spread.
Cool, then cut. Let cool in the baking dish for 5-10 minutes before cutting. Cutting while too hot causes the pieces to crumble — almond flour baked goods firm up as they cool. Cut into 12 even pieces.
One-bowl is the whole point - All eight ingredients go into the same bowl at once — dry ingredients first, wet ingredients second, stir to combine. No separate bowls, no creaming butter and sugar, no sifting. This is genuinely a five-minute prep recipe. The only knife work is dicing the jalapeños and grating the cheese, both of which take about 5 minutes combined.
Variations
Bacon jalapeño cheddar (the upgrade)
Fold ¼ cup of cooked crumbled sugar-free bacon into the batter along with the cheese and jalapeños. The bacon distributes throughout the cornbread and adds a smoky, salty note that plays extremely well against the cheddar and jalapeño. This is the version to make when you want to impress — it tastes like a poppers situation in cornbread form.
Green onion and cheddar (mild version)
Omit the jalapeños and add 3-4 thinly sliced green onions (both the white and green parts) to the batter. The green onion adds a subtle sharpness without heat and looks visually appealing scattered throughout the golden cornbread.
Everything but the jalapeños (plain cheddar)
The cornbread without jalapeños is a pure buttery cheddar almond flour bread that pairs with absolutely everything — soups, chili, eggs, as a base for open-faced breakfast sandwiches. Double the cheddar to 5 cups for an extremely cheesy version that is aggressively good.
Slightly sweet (more traditional cornbread flavor)
Add 2 tablespoons of Lakanto Powdered Monk Fruit Sweetener to the batter and omit the jalapeños. The subtle sweetness makes the almond flour taste more like traditional slightly-sweet cornbread. Add a drizzle of sugar-free honey (Nature's Hollow) on top after baking for the butter-and-honey cornbread experience.
Muffin format
Use a standard 12-cup muffin tin instead of the 9x13 baking dish. Divide the batter evenly — approximately ⅓ cup per cup. Bake at 350°F for 15-18 minutes until golden on top and a toothpick comes out clean. The muffin format is ideal for individual portions, meal prep, and freezing — freeze individually wrapped, reheat in the air fryer.
The Crouton Trick
This is the best use of leftover jalapeño cheddar cornbread that most people have never tried.
Cut leftover cornbread into approximately 1-inch cubes. Spread on the air fryer basket. Air fry at 360°F for 6-7 minutes until the cubes are golden and slightly crispy on the outside, still tender in the center.
These low carb croutons are exceptional on: tomato soup (the jalapeño and cheddar flavor is transformative), chili (sink them in and let them soak up the broth), egg-based breakfast dishes, or any green salad where you want a savory, cheesy crunch.
No air fryer: spread on a parchment-lined sheet pan, bake at 375°F for 10-12 minutes, turning once halfway through.
What to Serve With This Cornbread
Storage and Freezing
Room temperature: up to 3 days covered with plastic wrap or in an airtight container. Keep in a cool, dry spot.
Refrigerator: up to 1 week in an airtight container. Let come to room temperature before eating or warm briefly in the microwave (30 seconds at 70% power).
Freezer: up to 2-3 months. Cut into individual pieces, wrap each piece in plastic wrap, then place in a zip-lock freezer bag. The individual wrapping prevents freezer burn and allows you to thaw exactly as many pieces as you need.
Reheating from frozen: unwrap, microwave at 50% power for 60-90 seconds. Or thaw at room temperature for 20-30 minutes and warm in the oven at 300°F for 5 minutes. Air fryer at 300°F for 3-4 minutes produces the crispiest result.
Frequently Asked Questions
Does this actually taste like cornbread?
The texture is very similar — soft, slightly crumbly, rich. The flavor without sweet corn extract is cheesy, buttery, and savory with a mild corn-adjacent quality from the almond flour. With sweet corn extract (the optional ingredient), the corn flavor is genuine and most people can't distinguish it from traditional cornbread. The jalapeño and cheddar make it arguably more interesting than traditional cornbread.
Can I use coconut flour instead of almond flour?
Not as a 1:1 substitution — coconut flour absorbs significantly more liquid and requires a completely different ratio and additional eggs. A coconut flour cornbread is a different recipe. For this recipe, almond flour is required. Super fine blanched is the correct type — regular almond meal produces a grittier, denser result.
Why did my cornbread come out dense and gummy?
Three common causes: the almond flour wasn't super fine (coarser almond meal absorbs liquid differently and produces a denser result), the eggs were too cold (cold eggs don't emulsify as well — let them come to room temperature for 20-30 minutes before using), or it was underbaked (test with a toothpick in the exact center — if it comes out wet, return for 5 more minutes and test again).
Can I make this dairy-free?
The dairy components are sour cream, butter, and cheddar. Substitutes: sour cream → full-fat coconut cream or dairy-free sour cream (Forager makes a good one). Butter → refined coconut oil or vegan butter (same quantity). Cheddar → dairy-free cheddar shreds (Violife or Daiya — note these don't melt the same way and the flavor is different). The dairy-free version works but has a different texture and less pronounced cheese flavor.
How spicy is this exactly?
With 2 jalapeños, seeds removed: moderate warmth — similar to a jalapeño popper where the heat is present but not overwhelming. Most people who say they "don't do spicy" find this manageable. Children and very heat-sensitive people may prefer the no-jalapeño version. The heat mellows slightly during baking — fresh jalapeños in the batter are noticeably hotter than the finished baked product.
Can I use a different size pan?
An 8x8 or 9x9 square pan produces a thicker cornbread that takes approximately 5-8 more minutes to bake through — check with a toothpick at 25 minutes. A standard 9-inch round cake pan also works. The 9x13 produces the thinnest slices (about 1 inch thick) with the most even baking throughout.
