There’s nothing better than a muffin that tastes indulgent but is secretly wholesome. These gluten-free banana sweet potato muffins are soft, naturally sweet, and packed with nutrients — a breakfast that keeps you energized all morning.
Growing up, ripe bananas were never thrown away in my family. They were mashed, frozen, or turned into something comforting for breakfast. Sweet potatoes, on the other hand, are my secret ingredient whenever I want baked goods to stay moist without adding sugar or butter.
These gluten-free banana sweet potato muffins bring those two worlds together. They’re soft, naturally sweet (thanks only to bananas), dairy-free, and perfect for slow mornings, school lunches, or a mid-afternoon break with coffee or tea. No fancy ingredients, no refined sugar — just simple, nourishing comfort baked into a muffin.
They’re the kind of muffins I love baking on a Sunday afternoon, freezing in batches, and pulling out during the week for breakfast, school snacks, or a quick post-workout bite. Nourishing, comforting, and honestly… addictive in the best way.

Gluten-Free Banana Sweet Potato Muffin Recipe
These muffins come together with simple, wholesome ingredients — no refined sugar, no gluten, and no dairy. You’ll only need about 15 minutes and a muffin pan or muffin molds to prep.
Banana & Sweet Potato Muffin Ingredients
Sweet potatoes: Use firm, orange-fleshed sweet potatoes for the best color and natural sweetness. Boil them until soft, then peel and let them cool completely before mashing. Cooking them a few hours in advance — or even the day before — makes the muffins extra moist.
Bananas: The riper, the better! Look for bananas with plenty of brown spots. They’ll be sweeter and mash easily. In a pinch, you can speed up ripening by placing slightly green bananas in a paper bag with an apple for a day.
Almond and coconut flour: Make sure almond flour and coconut flour are finely ground. Coconut flour absorbs a lot of moisture, so measuring carefully ensures your muffins stay soft.
Almond butter & coconut oil: Use unsweetened almond butter for better control over flavor and sugar. Melt the coconut oil but let it cool slightly before mixing with eggs, so you don’t cook them by accident.
Eggs: Bring them to room temperature — it helps the batter mix more evenly and creates fluffier muffins.
Maple syrup: This ingredient is totally optional. You can skip it: the muffins will still be deliciously sweet thanks to bananas and sweet potatoes.
Nuts or add-ins: Chop walnuts roughly for a nice texture. You can swap them for pecans, chocolate chips, or raisins. Toasting nuts lightly enhances their flavor.
Choosing and Preparing the Bananas
Ripe bananas are key to the natural sweetness and soft texture of these muffins. The best bananas to use are fully ripe, with plenty of brown spots on the peel — they mash easily and bring out the best flavor without the need for added sugar.
If your bananas aren’t quite ready yet, there are a couple of easy ways to speed things up. You can place the bunch in a brown paper bag, fold it closed, and leave it on the counter for about 24 hours. Another quick option is to bake almost-ripe bananas in the oven at 250°F / 120°C for 15–20 minutes, until the skins darken and the flesh softens.
Can You Use Frozen Bananas?
Absolutely. If you have overripe bananas and no time to bake, freeze them whole (with the peel on) in a zip-top bag. When you’re ready to use them, let the bananas thaw completely at room temperature or overnight in the refrigerator.
Frozen bananas release more moisture as they thaw, so be sure to peel them and gently pat them dry with paper towels before mashing. This helps keep the muffin batter thick and prevents the muffins from becoming too wet.
Which Muffin Mold to Use
When baking these muffins, you have a few good options — all of them work well, so pick what’s easiest for you.
- Classic muffin tin: The most practical choice. Line it with paper liners or lightly grease it for easy removal.
- Disposable aluminum molds: Great if you’re baking for a crowd or want to gift some muffins. They hold their shape nicely and bake evenly. In this case, set the individual cups on a thin baking sheet before putting them in the oven. This makes moving them easier and helps them bake evenly.
- Silicone molds: Flexible, reusable, and convenient. They work well too, just make sure to place them on a flat surface.
How to Make Gluten-Free Banana Sweet Potato Muffins
Preparing the Wet Ingredients
In a large bowl, mash the cooled sweet potatoes together with the banana until smooth and creamy (1). A fork works perfectly — no blender needed.
Mixing the Dry Ingredients
In a separate bowl, combine almond flour, coconut flour, cinnamon, baking soda, and salt (2). Stir well to evenly distribute the leavening.
Bringing Everything Together
Add the dry ingredients to the sweet potato and banana mixture. Then mix in almond butter, melted coconut oil (3), maple syrup (if using), and eggs (4). Stir gently until you get a thick, uniform batter.
Fold in the chopped walnuts last, just until evenly distributed.
Baking the Muffins
Preheat your oven to 170°C / 340°F and line a muffin tin with paper liners or lightly grease it (5). If you use disposable aluminum molds, skip this step. Divide the batter evenly among the muffin cups, filling them about ¾ full.
Bake for 20 minutes, or until the tops are lightly golden and a toothpick inserted in the center comes out clean. Transfer the muffins to a wire rack and let them cool completely.
Storage & Freezing Tips
These muffins keep very well, which makes them perfect for meal prep. Once completely cooled, you can store them at room temperature for up to one day, as long as they’re well covered.
For longer storage, place them in an airtight container in the refrigerator, where they’ll stay fresh for up to four days without drying out.
If you’d like to plan ahead, these muffins also freeze beautifully. Store them in freezer-safe bags or containers for up to two months. When you’re ready to enjoy one, simply let it thaw at room temperature or warm it gently before serving.
Variations & Substitutions
- Swap walnuts for pecans or dark chocolate chips (sugar-free if needed)
- Add vanilla extract for extra aroma
- Use hazelnut butter instead of almond butter for a deeper flavor
- Add a pinch of nutmeg or ginger for a warmer spice profile
