Not all fats are created equal… in the oven, and this recipe is built around that truth. These banana muffins use refined avocado oil as the primary fat source, paired with almond flour for its natural fat content, whole-food density, and moisture-holding ability. The result is a batch of twelve muffins with a domed top, a clean golden crust, and a tender crumb that holds together without tasting heavy or greasy. No butter. No mystery oils. Just purposeful ingredients and the right pan for the job.
Fat Daddio’s anodized aluminum muffin pan is the tool behind consistent results here. Anodized aluminum conducts heat evenly from the base of each cup upward, so every muffin in the batch rises at the same rate and browns without scorching. Whether you are baking for the first time or the five hundredth, that kind of reliability matters.
Why Avocado Oil Is the Right Fat for Muffins
Avocado oil has a smoke point of approximately 500° F (260° C) when refined, which means it stays chemically stable at standard muffin baking temperatures of 350° F to 375° F (177° C to 191° C). Oils with lower smoke points, such as unrefined flaxseed or extra virgin olive oil, can break down under oven heat and introduce bitter or off-putting flavors into baked goods. Refined avocado oil does not have that problem.
Beyond heat stability, refined avocado oil has a neutral flavor profile. It does not compete with banana, vanilla, or warm spices the way coconut oil or butter can. It contributes richness and moisture without asserting itself, which makes it an ideal background fat for a recipe where you want other flavors to lead.
Avocado oil is also high in monounsaturated fats, particularly oleic acid, which is the same fatty acid associated with olive oil. This is why the baking community has started calling it one of the “good fats” alongside olive oil, almond fat, and avocado itself. It is a fat you can feel good about putting in food you are serving to people you care about.
The Role of Almond Flour in This Recipe
Almond flour is not just a gluten-free substitute. It is a fat-forward ingredient that does real structural work in this recipe. Ground almonds carry natural fat content (roughly 50% fat by weight), which contributes to moisture retention, a soft crumb, and a slightly denser texture than all-purpose flour muffins. That density is a feature here, not a flaw. These muffins are substantial without being heavy.
Almond flour also lacks gluten, which means the batter does not develop elasticity the way wheat-based batters do. The eggs and banana serve as the primary binders, and the avocado oil keeps everything cohesive and moist through the full bake.
Important: Use blanched almond flour, not almond meal. Almond meal is coarser and includes the skins, which produces a grainier, less consistent texture.
About the Fat Daddio’s MFN-12 Muffin Pan
The Fat Daddio’s MFN-STD muffin pan is made from anodized aluminum, a material that has been electrochemically hardened for durability, scratch resistance, and non-reactivity with acidic ingredients. Unlike reactive metals that can interact with baking soda or acidic fruits, anodized aluminum remains stable and neutral throughout the bake.
The pan holds twelve standard muffin cups, each designed for even heat distribution from the bottom up. This matters because uneven conduction is the primary cause of gummy muffin centers and over-browned bases. When heat moves uniformly through the pan, every cup sets at the same rate, giving you consistent rise, consistent browning, and consistent texture across the entire batch.
Fat Daddio’s anodized aluminum pans do not require greasing in the same way darker non-stick pans do, but for a clean release with almond flour batters (which have no gluten to help them hold together while hot), a light spray of avocado oil or the use of paper liners is recommended.
Ingredients
– 3 large ripe bananas, mashed (approximately 1 cup / 240g)
– 3 large eggs, room temperature
– 1/3 cup (80ml) refined avocado oil
– 2 tablespoons pure maple syrup (or honey)
– **1 teaspoon pure vanilla extract
– 2 1/2 cups (240g) blanched almond flour
– 1 teaspoon baking soda
– 1/2 teaspoon fine sea salt
– 1 teaspoon ground cinnamon
– 1/4 teaspoon ground nutmeg
– Optional mix-ins: 1/2 cup (85g) dark chocolate chips, chopped walnuts, or blueberries
Yield: 12 standard muffins
Prep time: 10 minutes
Bake time: 20 to 24 minutes
Total time: 30 to 34 minutes
Instructions
- Preheat your oven to 375° F (191° C). Place a rack in the center position. Lightly spray your Fat Daddio’s MFN-STD muffin pan with refined avocado oil, or line each cup with a paper muffin liner.
- Mash the bananas in a large mixing bowl until smooth. A few small lumps are fine, but aim for a mostly uniform consistency. The riper the bananas, the sweeter and more flavorful your muffins will be.
- Add the wet ingredients. To the mashed banana, add the eggs, avocado oil, maple syrup, and vanilla extract. Whisk until fully combined and the mixture looks uniform in color and consistency.
- Combine the dry ingredients in a separate medium bowl. Whisk together the almond flour, baking soda, salt, cinnamon, and nutmeg until no clumps remain. Almond flour tends to pack, so breaking it up before adding it to the wet ingredients helps ensure an even batter.
- Add the dry ingredients to the wet. Pour the almond flour mixture into the banana mixture and stir with a spatula or wooden spoon until a thick, uniform batter forms. Do not overmix. Fold in any optional mix-ins at this stage.
- Portion the batter into the prepared muffin pan, filling each cup approximately 3/4 full. Because this batter is denser than a standard wheat-flour batter, it will not overflow dramatically, but leaving room allows the top to dome properly during baking.
- Bake at 375° F (191° C) for 20 to 24 minutes, or until the tops are golden brown and a toothpick inserted into the center of a muffin comes out clean. Start checking at the 20-minute mark. Oven temperatures vary, and because Fat Daddio’s anodized aluminum distributes heat so efficiently, you may find the shorter end of the range is sufficient.
- Cool in the pan for 5 minutes before transferring to a wire rack. Allow the muffins to cool for at least 10 minutes before eating. Almond flour muffins firm up as they cool, so resist the urge to cut into them immediately.
Storage Tips
– Room temperature: Store in an airtight container for up to 2 days. Because these muffins contain no preservatives and are made with almond flour (which retains moisture), they can become soft if left uncovered.
– Refrigerator: Store in a sealed container for up to 5 days. Allow to come to room temperature before serving, or warm briefly at 300° F (149° C) for 5 minutes.
– Freezer: These muffins freeze exceptionally well. Wrap individually in plastic wrap and store in a freezer-safe bag for up to 3 months. Thaw overnight in the refrigerator or at room temperature for 1 to 2 hours.
Good Fat Substitutions
Avocado oil is the recommended fat for this recipe, but other “good fat” oils can be used depending on availability and flavor preference. Here is how each performs:
Refined Coconut Oil
Use the same amount (1/3 cup / 80ml), melted and cooled. Refined coconut oil has a smoke point of approximately 400° F (204° C), which is suitable for this recipe. It has a neutral flavor when refined (unrefined coconut oil will add a detectable coconut note). The texture of the finished muffin will be slightly firmer at room temperature because coconut oil solidifies below 76° F (24° C). These muffins will also have a marginally denser crumb compared to avocado oil.
High-Oleic Sunflower Oil
Use the same amount (1/3 cup / 80ml). High-oleic sunflower oil (not standard sunflower oil) has a smoke point above 440° F (227° C) and is high in monounsaturated fats, similar to avocado oil. The flavor is very neutral, and the texture of the finished muffin will be nearly identical to the avocado oil version. This is a solid option if avocado oil is not available.
What About Olive Oil?
Extra virgin olive oil is not recommended here. Its lower smoke point and strong flavor profile can produce a bitter or savory note in baked muffins. Light or refined olive oil (not extra virgin) can work in a pinch, with a smoke point around 465° F (240° C) and a milder flavor, but avocado oil or high-oleic sunflower oil will produce a cleaner result.
Baking Notes and Tips
– Ripe bananas matter. Bananas with dark spots or blackened skins are ideal. They are sweeter, softer, and more aromatic than yellow or green bananas. If your bananas are not ripe enough, place them unpeeled on a baking sheet and bake at 300° F (149° C) for 20 minutes until the skins turn black and the fruit softens.
– Room temperature eggs incorporate more smoothly into cold or room-temperature oil. If your eggs are cold from the refrigerator, place them in a bowl of warm water for 5 minutes before using.
– Do not skip the salt. Salt in sweet baked goods is not about making things salty. It sharpens every other flavor in the batter and keeps the muffins from tasting flat.
– Check your baking soda. Old baking soda is a common reason for muffins that do not rise properly. To test it, add a teaspoon to a small bowl of hot water. If it does not bubble actively, replace it.
– The Fat Daddio’s MFN-STD pan does not need to be rotated mid-bake because the anodized aluminum surface distributes heat evenly across the entire pan. If you are using a different pan, rotating halfway through may help even out hot spots.
