Almond Flour Blueberry Muffins
Tender grain-free muffins made with almond flour and blueberries, low in sugar and net carbs, so they won't spike blood sugar like a bakery muffin.
Why You'll Love This Recipe
Almond flour has no gluten in it, which sounds like a limitation and is mostly a freedom: there is no structure to develop and so nothing to overwork, and the batter can be stirred until it is perfectly smooth without going tough. What holds these together is the eggs, four of them, and that is also why the batter is thick enough to suspend a cup of blueberries rather than let them sink through and settle in a purple layer at the bottom of the tin. It is a Sunday job, one bowl, and breakfast is handled until Wednesday.
The sweetening is monk fruit or erythritol rather than sugar, and it is worth knowing what that changes in the tin. Sugar browns and it holds water; these do neither, so the tops come out paler than you will expect and the muffins are finished well before they look finished. Trust the toothpick over the color, or you will overbake them into something dry. Erythritol also leaves a faint cooling note on the tongue, which is what the cinnamon and the vanilla are quietly there to cover. Use honey or maple syrup instead if you would rather, the same third of a cup, and expect a darker top and a stickier crumb.
Four eggs and two and a half cups of ground almonds put real protein and fat into each of these, which is the whole difference between eating one at nine and being hungry again at half past ten, or not thinking about food until lunch. That is not a claim about willpower, it is what fat and protein do to the speed a breakfast leaves you. Olive oil in place of the butter makes them dairy-free and the crumb comes out the same, so that swap costs nothing at all. If you would rather have a loaf than a tin, our Almond Flour Banana Bread is built on the same idea and keeps just as well.
Ingredients
- 2 1/2 cups almond flour
- 4 large eggs
- 1 cup fresh blueberries
- 1/3 cup olive oil or melted butter (use olive oil to keep it dairy-free)
- 1/3 cup sugar-free sweetener (monk fruit or erythritol)
- 1 tsp ground cinnamon
- 1 tsp baking powder
- 1 tsp vanilla extract
- 1/4 tsp fine sea salt
Instructions
- Heat the oven and line the tin: Heat the oven to 350°F (175°C) and put paper liners in all twelve cups. Almond flour batter grips bare metal in a way wheat batter does not, and greasing alone will not save you, so use the papers even if you normally skip them. Let the oven come properly up to temperature before anything goes in, because these set from the outside in and a cool oven gives you a damp middle.
- Beat the wet until the sweetener dissolves: Whisk the eggs, oil, sweetener, and vanilla in a large bowl for a good minute, until you can no longer feel grit when you drag the whisk against the side. Granulated monk fruit and erythritol dissolve more slowly than sugar does, and anything still undissolved when the batter goes into the tin stays as a faint crunch in the finished muffin.
- Stir in the dry, then fold the berries: Add the almond flour, cinnamon, baking powder, and salt, and stir until the batter is uniformly smooth. There is no gluten here to toughen, so you cannot overmix it and there is no reason to be gentle. It will look far thicker than a wheat batter, closer to a soft dough, and that thickness is what holds the berries up. Now fold the blueberries through in a few strokes and stop, because every extra turn breaks another one and streaks the batter gray.
- Fill and bake: Divide the batter between the twelve cups, about three quarters full each, and bake 20 to 24 minutes. Here is the part that catches people: there is no sugar in these to brown, so they stay pale on top and look underdone when they are not. Go by a toothpick coming out clean and by the top springing back when you press it, and ignore the color entirely.
- Cool them in the tin, then out of it: Leave them in the tin for a full 10 minutes before you touch them. Almond flour muffins have no gluten holding them together and they are genuinely fragile while hot, so a muffin lifted at two minutes tears and one lifted at ten comes away from the paper clean. After that, move them to a rack. Left sitting in the warm tin they go on steaming from underneath and the bottoms turn damp, which is the one way these can disappoint you.
Variations
- Swap the berries: Raspberries or blackberries work in place of the blueberries. Chop the larger ones so they do not sink through the batter.
- Use real sweetener: Honey or maple syrup can replace the monk fruit spoon for spoon if you would rather not use a sugar substitute. Either one is an added sugar, so the muffins are no longer low in added sugar.
- Add lemon: The zest of one lemon in the batter sharpens the blueberry flavor considerably and costs nothing else.
- Add more protein: A scoop of unflavored protein powder can go in with the dry ingredients, though you will want an extra splash of milk to keep the batter loose.
- Keep it dairy-free: Choose the olive oil rather than the butter and the recipe is dairy-free exactly as written.
Storage & Leftovers
Airtight on the counter they hold for about two days, and up to a week in the refrigerator. Blueberries keep giving up a little moisture as they sit, so the liners darken around the fruit. That is the berries, not a fault, and it does not change how they eat.
To freeze, cool completely and freeze in an airtight container for up to 2 to 3 months; thaw at room temperature or warm briefly before serving.
Fifteen seconds in the microwave is enough to loosen a cold muffin and wake the cinnamon back up. If the oven is already on for something else, five minutes at 300°F (150°C) is better still, because it dries the surface slightly instead of steaming it.
Notes & Tips
- Toss the berries in a little of the flour: Coated berries stay suspended in the batter instead of settling into a purple layer at the bottom of each cup.
- Fold, do not stir: Blueberries burst easily. A few gentle turns with a spatula keeps them whole and keeps the crumb from turning gray.
- Use liners: These are tender and moist, and they stick to a bare tin no matter how well you grease it.
- Check early: Almond flour browns ahead of wheat. Start testing at twenty minutes so the edges do not dry out while you wait for color.
- Let them cool in the tin: They firm up as they cool and lift out cleanly after about ten minutes. Pulled hot, they fall apart.
- Make it ahead: These freeze well. Wrap them individually and thaw overnight, or warm one in a low oven for a few minutes.
Nutrition & Mindful Eating
- Ground almonds, eggs and olive oil carry these between them. The almond flour makes the crumb soft, the eggs give it lift and hold it together, and the oil keeps it moist a day or two on, so the fruit sits in something rich.
- Almond flour is the body of these muffins, fine and faintly sandy, giving a crumb that stays tender in the middle. It also carries the vitamin E and magnesium that come along with the whole nut.
- Whole eggs are doing structural work here, setting the almond flour into something closer to a soft cake than a dry crumb, and the yolks are where the choline, the lutein and the color of the finished muffin come from.
- Blueberries go in whole and burst as they bake, leaving warm pockets of juice through the middle. That deep blue skin is anthocyanin pigment, which has been studied for its links to blood vessel and memory health.
- Cinnamon and a pinch of fine salt are the finish. The cinnamon warms the almonds as they toast, and the salt sharpens the fruit so that every bite tastes rounded rather than flat.
- As you eat, notice the crumb giving way and the pockets where the berries went jammy, and slow down enough to tell when one muffin has actually satisfied you.
