Key Ingredients & Substitutions

Almond and Coconut Flours: These gluten-free flours are low in carbs and high in fiber, making them perfect for keto baking. (I'm a fan of this almond flour and this coconut flour.)

Low Carb Sweetener: Choose any keto-friendly granulated sweetener that you prefer, like erythritol or monk fruit sweetener to keep these muffins sugar-free. I used this monkfruit sweetener.

Banana Extract: This gives the muffins their banana flavor without adding the sugar and carbs found in actual bananas. No real substitute here — it's what makes these muffins stand out! (You can order it online here.)

Walnuts: These add a crunchy texture and some healthy fats. Feel free to substitute with pecans or leave the nuts out entirely if you prefer.

Helpful Tips

Use Room Temperature Ingredients. Make sure your eggs and almond milk are at room temperature to ensure the batter mixes together smoothly.

Do Not Overmix! Mix the batter until just combined to avoid dense muffins.

Watch the Baking Time. Oven temperatures can vary, so start checking your muffins at the 18-minute mark to prevent overbaking.

Storing the Muffins: The banana muffins will stay fresh at room temperature for 3-5 days. You can also freeze them for 2-3 months. Simply defrost to room temperature to serve again.

Chocolate Chip Keto Banana Muffins: Fold in sugar-free chocolate chips instead of walnuts for a chocolatey twist.

Blueberry Keto Banana Muffins: Add a handful of fresh or frozen blueberries to the batter for a burst of tanginess.

Nut-Free Keto Banana Muffins: For a nut-free version, omit the walnuts and substitute the almond flour for additional coconut flour. Consider adding seeds like sunflower or pumpkin for a bit of crunch.

Citrus Banana Muffins: Add a bit of lemon zest for an extra zing of flavor.
