Made with just coconut and oat flour, they’re naturally low in oxalates and easy on sensitive systems. Forty minutes start to finish, with most of that being hands-off oven time.
Why You’ll Love This Recipe
- Naturally gluten-free. Coconut flour and oat flour replace wheat, both are on the low-oxalate grains list.
- Sweetened with honey. No refined sugar; just real honey for natural sweetness.
- Soft and fluffy texture. The combination of coconut flour, oat flour, and apple cider vinegar gives these muffins a tender crumb that rivals traditional flour muffins.
- Loaded with blueberries. Three-quarters of a cup folded in for a juicy berry in every bite.
- Naturally low oxalate. Every ingredient is on the safe list, including the blueberries, one of the safest fruits for an oxalate-sensitive diet.
Why Coconut and Oat Flour?
Wheat flour is high in oxalates, which rules out most traditional baked goods on a low-oxalate diet. Coconut flour and oat flour are two of the cleanest alternatives, both are explicitly on the low-oxalate grains list, and they work beautifully together. Coconut flour brings tenderness and a subtle sweetness; oat flour adds structure and a familiar wholegrain flavor. Together they produce a muffin that feels just like a regular blueberry muffin in texture, even though it’s grain-free in the wheat sense.
Ingredient Notes

- Coconut flour. Highly absorbent, it pulls moisture from the batter, which is why this recipe uses generous amounts of liquid (eggs, coconut milk, oil, honey). Don’t substitute another flour at the same volume; coconut flour behaves very differently.
- Oat flour. Look for certified gluten-free if cross-contamination matters to you. You can also make your own by blending rolled oats in a high-powered blender or food processor.
- Eggs. Three large eggs at room temperature provide the structure for these gluten-free muffins. Cold eggs cause the fats to seize, leading to dense, uneven texture.
- Apple cider vinegar. The secret ingredient, it reacts with the baking soda to give the muffins extra lift. You won’t taste it in the finished muffins.
- Coconut milk. Canned, full-fat coconut milk for the best richness. The creaminess balances the lighter oat flour.
- Honey. Use real honey, not honey-flavored syrup. The flavor of real honey complements the blueberries beautifully.
- Blueberries. Fresh or frozen both work. If using frozen, don’t thaw, toss them frozen straight into the batter to prevent bleeding.
How to Make Gluten-Free Blueberry Muffins
Full step-by-step is in the recipe card below. Big picture:
- Preheat to 335°F. Lower than typical because coconut flour browns aggressively above 350°F.
- Whisk dry ingredients in one bowl: coconut flour, oat flour, baking soda, baking powder, salt.
- Whisk wet ingredients in another bowl: eggs first for a full minute, then add vinegar, coconut milk, avocado oil, honey, and vanilla.
- Combine wet into dry and stir just until incorporated. Don’t over-mix.
- Fold in the blueberries.
- Spoon into muffin cups, you’ll get 7 to 8 muffins.
- Bake 25 to 30 minutes until a toothpick comes out clean.
- Cool 15 minutes on a wire rack before serving.

Gluten-Free Blueberry Muffins
Print Recipe
Ingredients
- 1/2 cup + 1 tbsp coconut flour
- 1/2 cup oat flour
- 3/4 tsp baking soda
- 1 tsp baking powder
- 1 pinch sea salt
- 3 large eggs room temperature, see notes
- 1.5 tbsp apple cider vinegar
- 1/2 cup canned coconut milk
- 1/4 cup avocado oil
- 1/3 cup honey
- 1.5 tsp vanilla extract
- 3/4 cup blueberries rinsed and dried completely
Instructions
- Preheat the oven to 335°F (170°C). Coconut flour can start to burn at 350°F, so the slightly lower temperature prevents browning the tops too quickly.
- A silicone muffin pan is ideal because it doesn’t need cupcake liners. If using a metal pan, line with cupcake liners or grease the wells well.
- In a large bowl, whisk together the coconut flour, oat flour, baking soda, baking powder, and sea salt.
- In a medium bowl, crack the eggs and whisk vigorously for about a minute. Add the apple cider vinegar, coconut milk, avocado oil, honey, and vanilla extract. Whisk for another 30 seconds to fully combine.
- Pour the wet ingredients into the dry ingredients and stir with a whisk until just combined. Do not over-mix — over-mixing leads to dense muffins.
- Gently fold in the blueberries.
- Using two spoons, divide the batter evenly into the muffin pan. You should get 7–8 muffins depending on how full you fill each cup.
- Bake at 335°F for 25–30 minutes. Test with a toothpick — it should come out clean (or with a few moist crumbs) when the muffins are done.
- Let the muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool for at least 15 minutes more. Serve warm, or store in an airtight container for up to 3 days.
Pro Tips for the Best Muffins
- Use room-temperature eggs. This is the single biggest texture variable. Cold eggs cause the oil to seize and the batter to clump. Warm cold eggs in a bowl of warm water for 5 to 10 minutes if you forgot to take them out earlier.
- Don’t over-mix. Stir just enough to combine. Coconut flour batters get dense fast if you keep mixing.
- Use a silicone muffin pan if you have one. No liners needed and the muffins release cleanly. If using metal, line with paper cupcake liners.
- Watch the bake time closely. Coconut flour can go from underbaked to overbaked quickly. Start checking at 25 minutes.
- Cool fully before storing. Trapped steam in a closed container makes the tops gummy.
Storage and Reheating
- Room temperature. Store in an airtight container or plastic bag for up to 3 days.
- Refrigerator. Keep for up to a week, they’ll firm up slightly when chilled.
- Freezing. Wrap individually and freeze for up to 3 months. Thaw at room temperature or microwave for 20 to 30 seconds for a warm muffin.
- Reheating. A 10-second microwave or 5 minutes in a 300°F oven brings back the just-baked texture.
Substitutions and Variations
- Use maple syrup instead of honey, both are low-oxalate sweeteners.
- Swap blueberries for strawberries for a different berry muffin (chop them small first).
Frequently Asked Questions
Are these blueberry muffins low oxalate?
Yes. Coconut flour, oat flour, eggs, coconut milk, honey, and blueberries are all on the low-oxalate list. The recipe avoids the usual high-oxalate culprits in baked goods (wheat flour, ground cinnamon, almond flour) while still delivering a muffin texture that feels traditional.
Can I substitute another flour for the coconut flour?
Coconut flour is highly absorbent and behaves very differently from other flours, you can’t swap it 1:1 with anything else. If you don’t have coconut flour, this isn’t the right recipe. Try a different gluten-free blueberry muffin recipe designed for whatever flour you do have.
Can I use frozen blueberries?
Yes. Don’t thaw them first, toss them into the batter while frozen. This prevents them from bleeding their color into the surrounding batter as they bake.
Why such a low oven temperature?
Coconut flour starts to brown and burn around 350°F, which gives you dark muffin tops before the inside is fully baked. The 335°F temperature lets the muffins set through the middle without scorching the tops.
