I have been making these muffins and tweaking the recipe for so long that I genuinely don’t know where they came from. Somewhere along the line they became my muffins — the version I bring to friends’ kids, the version I bake on a slow Sunday morning when my partner asks for something warm and comforting, the version everyone asks for after the first bite.
They are not cheap. A cup of raw cashew butter, three ripe bananas, two pastured eggs, frozen organic blueberries — these add up to a few dollars per muffin in ingredients. But they’re perfect for satisfying a comfort-food craving or a weekend family treat without creating any sugar chaos, spikes, and crashes. Calorie-dense, fun to make, and loved by everyone we feed them to.
Why this version works
Most “healthy” muffin recipes still have a flour base — almond, coconut, oat, or some blend of all three. These don’t. The structural choice that makes them different is raw cashew butter as the binder. It does the job that flour usually does (holding the crumb together) while also adding fat, protein, and a soft buttery texture that almond and coconut flour can’t match.
The result is calorie-dense in a real-food way — the kind of dense that comes from eggs, fruit, and a full cup of nut butter rather than from refined sugar and seed oil. One muffin will hold a hungry kid (or a hungry adult) for hours. They’re particularly good for:
- A weekend family breakfast with a side of berries
- A snack that fuels through an afternoon without crashing
- Calorie support if you’re trying to gain weight in a clean way (most “healthy” baked goods don’t have enough density for this — these do)
- A kid-friendly treat that you actually feel good about handing over
Raw cashew butter is the make-or-break ingredient
This recipe rises or falls on cashew butter quality. It has to be raw for the flavor to land right — roasted cashew butter tastes flatter and grittier, and the muffins lose their soft, custardy interior.
A few sourcing notes:
- Buy a brand you trust. Most grocery-store cashew butters use roasted cashews and inconsistent processing. My favorite is Artisana Organics Raw Cashew Butter — raw, single-ingredient, no added oils — in either a single 14 oz jar or, since this recipe uses a full cup, the large 8 lb tub. Buy local first if you have a good source. The rest of the exact ingredients I use are linked individually too — Ceylon cinnamon, Madagascar vanilla beans, fine Celtic sea salt, baking soda, silicone muffin cups, and unbleached parchment.
- Store cold once opened. If you buy in bulk, keep it in the fridge or a cold garage — raw cashew butter can develop funk at room temperature over time.
- Bring it back to soft before you bake. Cold cashew butter is rock-hard and impossible to stir into a smooth batter. Two ways to handle it: scoop your one cup into a measuring cup and sit the cup in a bowl of hot water for about 20 minutes; or take a cup out hours before and let it come to room temperature on the counter. Either way you want it more liquid than solid.
Sweetener: bananas do the work
These muffins were originally written with a tablespoon of maple syrup or honey or molasses for backup sweetness — and that version is great too. But over time I’ve moved to the fruit-only version, and that’s the one I make now. Three very ripe bananas plus a cup of blueberries is plenty of sweetness for a comfort-food treat that doesn’t ask your blood sugar to do anything dramatic.
If you want a touch more sweetness — for a special occasion, or because your bananas weren’t quite ripe enough — go ahead and add the optional tablespoon of maple, honey, or molasses. Each gives a slightly different flavor: maple is round and clean, honey is floral, molasses is dark and almost caramel-like with the cinnamon.
Banana ripeness matters
Plan your muffin-making for when you have three very ripe bananas — the spotted, speckled, almost-too-soft ones. Underripe bananas (still firm, no spots) will leave you with a muffin that tastes flat and faintly starchy. Ripe bananas bring the sweetness and the soft, custardy texture that makes these so good.
If you want to plan ahead, buy bananas a week before you want to bake. Or freeze your too-ripe bananas in the peel and thaw them on the counter the morning you bake (drain the extra liquid).
How we eat them
A few of the ways these show up in our kitchen:
- Warm from the oven with a small spoon of ghee* or grass-fed butter on top. This is the move. The butter melts into the muffin and the whole thing tastes like the best version of a banana bread you’ve ever had. (*Ghee is clarified butter — most folks with dairy sensitivities tolerate it well.)
- Lunchbox snack. Two muffins + a hard-boiled egg + a piece of fruit = a solid kid lunch that doesn’t crash anyone.
- Hike or travel food. Calorie-dense, sturdy, no special storage needed for a day.
- With a cashew milk mate latte for a slow weekend breakfast. The cashew flavor carries beautifully between the two.
Storage and best-overs
These keep really well — better than most baked goods.
- Room temperature: 2 days in a sealed container on the counter.
- Fridge: Up to a week. Warm one in a toaster oven for 5 minutes before eating to bring back the soft interior.
- Freezer: Up to 3 months. Wrap individually in parchment, then in a freezer bag. Pull out the night before and let it thaw on the counter, or warm straight from frozen at 300°F for 15 minutes.
Recipe
Flourless Banana Cashew Butter Muffins
Prep: 15 min · Cook: 30 min · Total: 60 min · Yield: 12 muffins
Ingredients
- 1 cup raw cashew butter (brand matters — see notes)
- 3 very ripe bananas (the sweeter the better)
- 2 eggs
- 1 cup frozen blueberries
- 2 teaspoons cinnamon
- 1 teaspoon vanilla extract (or 1 whole vanilla bean, scraped)
- 1 teaspoon baking soda
- A sprinkle of sea salt
- Optional: 1 tablespoon maple syrup, honey, or molasses (I make these with fruit only)
- To serve: ghee* or grass-fed butter on top while warm
* Ghee is clarified butter — the milk solids have been removed, so many people who can’t tolerate other dairy do well with it. Skip it if dairy doesn’t work for your body.
Instructions
- Preheat the oven to 350°F (180°C). Line a 12-cup muffin tin with silicone liners or unbleached paper liners.
- In a large bowl, whisk together the cashew butter, eggs, vanilla, cinnamon, baking soda, salt — and the optional sweetener if you’re using it — until smooth and batter-like. (If the cashew butter is too firm to stir, see the pro tip above for warming it.)
- Slice the bananas about ⅛-inch thick.
- Gently fold the banana slices and frozen blueberries into the batter, just enough to disperse the fruit evenly. Don’t overmix — you want intact banana slices, not mashed.
- Spoon the batter into the prepared muffin cups, filling each about ¾ full.
- Bake for 30 minutes, or until a fork inserted in the center comes out clean.
- Cool in the tin for 5 minutes, then transfer to a rack. Serve warm with a small spoon of ghee or grass-fed butter on top if you want — it melts into the muffin and is incredible.
A final note
These are the muffins I’d put in front of a skeptic — the kid who only eats packaged snacks, the partner who thinks “healthy baking” means dry and disappointing, the friend who doesn’t believe you can make something this comforting without flour or sugar. One bite and the argument’s over. The trick is just three ripe bananas, a good cup of raw cashew butter, and enough cinnamon to make the kitchen smell like a Sunday morning should.
Until next time, have a beautiful day.
