4.8 from 4 reviews

This delicious gluten-free cornbread made with polenta and rice flour (with no xantham gum!) makes the best gluten-free cornbread muffins ever. They are easy to make with just one bowl and have a sweet, buttery flavor and dense, hearty texture. (gluten-free, nut-free)


  • 1 cup polenta
  • 1/2 cup  brown rice flour (or white rice flour)
  • 2 tbsp ground flaxseed
  • 2 tbsp granulated sugar
  • 1 tbsp baking powder
  • 1/2 tsp salt
  • 1 1/4 cups buttermilk
  • 1 large egg
  • 3 tbsp butter, melted and cooled


  1. Heat oven to 400°F. Line a muffin tin with paper or silicone liners, or spray with oil.
  2. In a large bowl, combine polenta, rice flour, flaxseed, sugar, baking powder and salt.
  3. Add wet ingredients and whisk well to combine.
  4. Scoop batter into muffin tin, filling cups 3/4 of the way full.
  5. Bake 10-15 minutes, or until tops are lightly golden and centers are set.
  6. Remove from oven and cool slightly before removing from the pan.


  • To make one big pan: pour batter into a greased 8 or 9-inch dish and bake for 23-26 minutes, or until the top is golden and a toothpick inserted into the center comes out clean.
  • If the batter sits for a bit, it might start to separate. That's ok, just give it another good whisk before pouring into the dish or muffin tin, then bake right away. Because there is no gluten, you don't have to worry about over-whisking.
  • Careful not to over-bake. Especially with the muffins, they'll dry out if they bake too long. You're looking for golden tops and a toothpick inserted in the center to come out clean when they're done.
  • If you made muffins (especially without liners), wait at least 10 minutes for them to cool before removing them from the muffin tin so that they don't fall apart.
  • If you like your cornbread more sweet, you can use up to 1/4 cup sugar.
