Servings 12 servings

Ingredients

  

• 2 cups fine almond flour
• 2 tablespoons coconut flour
• 1/2 cup granulated keto sweetener (erythritol, allulose, or monk fruit blend)
• 1 1/2 teaspoons baking powder
• 1/2 teaspoon baking soda
• 1/2 teaspoon fine sea salt
• 1 teaspoon ground cinnamon
• 3 large eggs, room temperature
• 1/2 cup full-fat Greek yogurt (or sour cream)
• 1/4 cup unsalted butter, melted and slightly cooled (or refined coconut oil)
• 2 teaspoons maple extract (not syrup)
• 1 teaspoon vanilla extract
• 1/3–1/2 cup unsweetened almond milk, as needed
• 3/4 cup chopped walnuts, plus extra for topping
• Optional: 1–2 tablespoons sugar-free maple syrup for brushing tops

Instructions

 

• Preheat and prep. Heat the oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or grease well. Lightly spray the liners if you have them to prevent sticking.
• Mix dry ingredients. In a large bowl, whisk almond flour, coconut flour, sweetener, baking powder, baking soda, salt, and cinnamon until no lumps remain.
• Whisk wet ingredients. In a separate bowl, whisk eggs, Greek yogurt, melted butter, maple extract, and vanilla until smooth. Stir in 1/3 cup almond milk.
• Combine batter. Pour wet into dry and fold until just combined. If the batter seems too thick (it should be scoopable, not pourable), add up to 2 more tablespoons almond milk.
• Fold in walnuts. Stir in the chopped walnuts gently so the batter stays airy.
• Fill the cups. Divide batter evenly among the muffin cups, filling each about 3/4 full. Sprinkle a few extra walnuts on top for crunch.
• Bake. Bake for 18–22 minutes, until the tops are set and a toothpick comes out mostly clean with a few moist crumbs.
• Finish and cool. Let muffins cool in the pan for 5–10 minutes, then transfer to a rack. For extra maple aroma, lightly brush warm tops with sugar-free maple syrup (optional).
• Serve. Enjoy warm or at room temperature. The flavor deepens after a few hours as the spices settle.

Why This Recipe Works

Save

• Almond flour keeps it moist. It adds structure and a soft crumb without the dryness you get from coconut flour alone.
• Maple flavor, not maple syrup. Using a maple extract and a keto-friendly sweetener gives you that nostalgic taste without the carbs.
• Greek yogurt for lift and tenderness. It adds moisture and a gentle tang while helping the muffins rise.
• Chopped walnuts add crunch. Toasty bits make every bite interesting and extra satisfying.
• Balanced sweetness. The combination of erythritol/monk fruit sweetener and a touch of cinnamon delivers a warm, cozy flavor.

Ingredients

• 2 cups fine almond flour

How to Make It

Save

1. Preheat and prep. Heat the oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or grease well.

   Lightly spray the liners if you have them to prevent sticking.

2. Mix dry ingredients. In a large bowl, whisk almond flour, coconut flour, sweetener, baking powder, baking soda, salt, and cinnamon until no lumps remain.
3. Whisk wet ingredients. In a separate bowl, whisk eggs, Greek yogurt, melted butter, maple extract, and vanilla until smooth. Stir in 1/3 cup almond milk.
4. Combine batter. Pour wet into dry and fold until just combined. If the batter seems too thick (it should be scoopable, not pourable), add up to 2 more tablespoons almond milk.
5. Fold in walnuts. Stir in the chopped walnuts gently so the batter stays airy.
6. Fill the cups. Divide batter evenly among the muffin cups, filling each about 3/4 full.

   Sprinkle a few extra walnuts on top for crunch.

7. Bake. Bake for 18–22 minutes, until the tops are set and a toothpick comes out mostly clean with a few moist crumbs.
8. Finish and cool. Let muffins cool in the pan for 5–10 minutes, then transfer to a rack. For extra maple aroma, lightly brush warm tops with sugar-free maple syrup (optional).
9. Serve. Enjoy warm or at room temperature. The flavor deepens after a few hours as the spices settle.

How to Store

• Room temperature: Keep in an airtight container for up to 2 days.

  Add a paper towel to absorb moisture.

• Refrigerator: Store in a sealed container for 5–6 days. Warm in the microwave for 10–15 seconds before eating.
• Freezer: Wrap individually and freeze for up to 2 months. Thaw overnight in the fridge or reheat from frozen at 300°F (150°C) for 8–10 minutes.

Health Benefits

• Low in net carbs. Almond and coconut flours keep carbs in check while providing fiber and healthy fats.
• Blood sugar friendly. Using erythritol, allulose, or monk fruit avoids spikes you’d get from traditional maple syrup and sugar.
• Heart-healthy fats. Walnuts bring omega-3s and antioxidants that support brain and heart health.
• Protein boost. Eggs and Greek yogurt add protein to keep you fuller for longer.

Common Mistakes to Avoid

• Overmixing the batter. Stir just until combined to prevent dense muffins.
• Skipping the liners or grease. Almond flour sticks more than wheat flour.

  Properly line or grease the pan to avoid tearing.

• Overbaking. Keto muffins dry out quickly. Check early and pull when the centers are set but still moist.
• Using too much coconut flour. It’s very absorbent. Stick to the small amount listed to avoid a crumbly, dry texture.
• Using liquid sweeteners. Regular maple syrup or honey will raise carbs and change the batter consistency.

Alternatives

• Dairy-free: Swap Greek yogurt for thick coconut yogurt and butter for refined coconut oil.

  Use unsweetened almond or coconut milk.

• Different nuts: Pecans or chopped almonds work well. For a nut-free version, try sunflower seeds and sunflower seed flour (note: it may tint green when baked, which is harmless).
• Spice it up: Add nutmeg or a pinch of cloves. For a fall vibe, mix in pumpkin pie spice and a spoonful of pumpkin puree (reduce almond milk slightly).
• Extra flavor: Stir in sugar-free chocolate chips or a swirl of sugar-free maple syrup into the batter for a marbled look.
• Sweetener swaps: Allulose gives a softer crumb and browns more.

  Erythritol is crisper and sweeter. Adjust to taste.

FAQ

Are these muffins actually maple-flavored without real maple syrup?

Yes. Maple extract brings strong maple aroma and taste without the sugar.

A light brush of sugar-free maple syrup on top can boost the flavor further without adding many carbs.

Can I make them egg-free?

Keto muffins rely on eggs for structure. You can try flax eggs (1 tablespoon ground flax + 2.5 tablespoons water per egg), but expect a denser texture and less rise.

What’s the net carb count per muffin?

It varies by brand and portion, but typically you’ll get about 3–4 net carbs per muffin when made as directed and divided into 12 muffins. Always calculate with your exact ingredients.

Do I need both almond and coconut flour?

Using both creates a better crumb.

Almond flour gives body and moisture, while a little coconut flour helps bind and balance the texture.

How can I tell when they’re done?

Look for lightly golden edges and a center that springs back. A toothpick should come out with a few moist crumbs, not wet batter.

Can I make mini muffins?

Absolutely. Fill mini muffin cups about 3/4 full and bake for 10–13 minutes, checking early.

They’re perfect for snacks or lunch boxes.

What if I don’t have maple extract?

Use vanilla and a touch of caramel extract for warmth. It won’t be as maple-forward, but it still tastes great. Consider adding the sugar-free maple syrup brush on top.

Why are my muffins crumbly?

They may be overbaked or short on moisture.

Next time, add a tablespoon more almond milk or yogurt and pull them from the oven sooner.
