If you miss apple muffins on a low-carb lifestyle, these keto apple muffins bring that cozy bakery vibe back without the sugar crash. They’re soft, warmly spiced, and satisfying—perfect for breakfast, snacks, or a quick treat with coffee. You’ll get the flavor and aroma you love, but with smart swaps to keep carbs in check.

The best part? They’re easy to make and use simple ingredients you can find in most grocery stores. Expect tender crumbs, cinnamon warmth, and just the right amount of sweetness.

What Makes This Special

• Real apple flavor with fewer carbs: A small amount of real apple plus apple pie spice and vanilla gives that classic taste without going overboard.
• Moist and tender texture: Almond flour and a touch of coconut flour create a soft crumb that feels like a bakery muffin.
• No sugar spikes: Made with erythritol or allulose, these muffins stay low in net carbs and keto-friendly.
• Meal-prep friendly: They store well and freeze beautifully, so you can grab-and-go all week.
• Customizable: Add nuts, swap spices, or make them dairy-free with simple tweaks.

Ingredients

• 2 cups fine blanched almond flour
• 2 tablespoons coconut flour
• 1 tablespoon ground cinnamon
• 1 teaspoon apple pie spice (or an extra 1/2 teaspoon cinnamon plus 1/4 teaspoon nutmeg and a pinch of allspice)
• 1 1/2 teaspoons baking powder
• 1/2 teaspoon baking soda
• 1/4 teaspoon fine sea salt
• 1/2 cup granulated erythritol or allulose (adjust to taste)
• 3 large eggs, room temperature
• 1/3 cup unsweetened almond milk (or other low-carb milk)
• 1/3 cup melted butter or ghee (for dairy-free, use refined coconut oil)
• 1 teaspoon vanilla extract
• 1/2 teaspoon apple extract (optional but boosts apple flavor)
• 1 small tart apple (about 100–120 g), peeled and finely diced
• 1 tablespoon lemon juice (to toss with the apple)
• Optional add-ins: 1/3 cup chopped walnuts or pecans, or 1–2 tablespoons sugar-free caramel chips
• Optional topping: a sprinkle of cinnamon “sugar” (1 tablespoon sweetener mixed with 1/2 teaspoon cinnamon)

Step-by-Step Instructions

1. Prep the pan: Preheat your oven to 350°F (175°C).
   

   Line a 12-cup muffin tin with paper liners or grease well.

2. Mix dry ingredients: In a large bowl, whisk together almond flour, coconut flour, cinnamon, apple pie spice, baking powder, baking soda, salt, and sweetener until no lumps remain.
3. Whisk wet ingredients: In a separate bowl, beat the eggs, almond milk, melted butter, vanilla, and apple extract (if using) until smooth and slightly frothy.
4. Combine: Pour the wet mixture into the dry and stir with a spatula until just combined. The batter will be thick but scoopable. Let it rest for 3–4 minutes so the coconut flour hydrates.
5. Prep the apple: Toss the finely diced apple with lemon juice.
   

   Pat dry with a paper towel to reduce extra moisture. Fold apple pieces into the batter. Add nuts if using.

6. Fill the cups: Divide the batter evenly among the 12 muffin cups, filling each about 3/4 full.
   

   Sprinkle with the cinnamon “sugar” topping if you like.

7. Bake: Bake for 18–22 minutes, or until the tops are set and a toothpick comes out with a few moist crumbs. Do not overbake.
8. Cool: Let muffins cool in the pan for 10 minutes, then move to a rack to cool completely. They firm up as they cool.
9. Serve: Enjoy warm with a pat of butter, or at room temperature.
   

   They pair perfectly with coffee or tea.

Storage Instructions

• Room temperature: Store in an airtight container for up to 2 days.
• Refrigerator: Keeps well for 5–6 days. Reheat briefly in the microwave or toaster oven for a fresh-baked feel.
• Freezer: Freeze in a single layer, then transfer to a freezer bag. Good for up to 2 months.
  

  Thaw overnight in the fridge or warm from frozen at 300°F (150°C) for 8–10 minutes.

Health Benefits

• Lower carb count: Almond and coconut flours reduce net carbs compared to wheat flour, supporting ketosis and stable energy.
• Healthy fats: Almond flour and butter provide satiating fats that help keep you full longer.
• Fiber-rich: Nut flours and a bit of apple add fiber for smoother digestion and steadier blood sugar.
• No refined sugar: Using erythritol or allulose keeps sweetness high and sugars low.
• Protein boost: Eggs add structure and a satisfying protein punch per muffin.

What Not to Do

• Don’t use too much apple: A little goes a long way. Extra apple adds carbs and moisture, which can make the muffins soggy.
• Don’t skip the rest time: Letting the batter sit for a few minutes keeps the texture tender and prevents crumbly muffins.
• Don’t overbake: Almond flour browns quickly. Pull them when the tops are set and a toothpick has moist crumbs.
• Don’t pack the flour: Scoop and level almond flour gently to avoid dense muffins.
• Don’t swap sweeteners blindly: Allulose browns more and tastes less sweet than erythritol.
  

  Adjust bake time and quantity if you switch.

Variations You Can Try

• Apple-cinnamon crunch: Add 1/3 cup chopped pecans and a sprinkle of cinnamon “sugar” on top for texture.
• Maple-spice: Add 1 teaspoon sugar-free maple extract and a pinch of cloves for a fall-inspired twist.
• Caramel apple: Fold in 1–2 tablespoons sugar-free caramel chips and finish with a light drizzle of keto caramel sauce.
• Dairy-free: Use refined coconut oil instead of butter and unsweetened coconut milk instead of almond milk.
• Apple-zucchini blend: Replace half the apple with finely grated, well-squeezed zucchini to cut carbs and add moisture.
• Mini muffins: Bake in a mini muffin tin for 10–12 minutes. Great for portion control and kid-friendly snacks.

FAQ

Are apples keto-friendly?

Apples are higher in carbs than most keto fruits, but using a small amount spread across the batch keeps net carbs low per muffin. You still get real apple flavor without breaking your macros.

Can I make these without coconut flour?

Yes, but you’ll need a bit more almond flour since coconut flour absorbs more liquid.

Replace the 2 tablespoons coconut flour with about 1/2 cup almond flour and reduce the almond milk slightly. The texture will be a touch more tender.

What’s the best sweetener to use?

Erythritol or a blend with monk fruit works well and keeps the crumb light. Allulose makes a softer, moister muffin and browns more quickly, so watch the bake time and consider adding 1–2 tablespoons more if you prefer the same level of sweetness.

How many carbs are in each muffin?

Exact numbers depend on brands and add-ins, but a typical batch yields about 3–5 grams net carbs per muffin when using erythritol, a small apple, and no caramel chips.

For precision, plug your ingredients into a nutrition calculator.

Can I use applesauce instead of fresh apple?

It’s not ideal for keto. Even unsweetened applesauce adds more carbs and extra moisture. If you must, use a very small amount—1–2 tablespoons—and reduce the almond milk slightly.

Why are my muffins crumbly?

Common causes include overbaking, skipping the batter rest, or not enough binding.

Make sure eggs are large, measure flours correctly, and let the muffins cool before removing liners.

How do I get a stronger apple flavor?

Use a touch of apple extract along with the fresh apple, and don’t skip the cinnamon and apple pie spice. Warm spices amplify the apple notes without extra carbs.

Can I make them nut-free?

Almond flour is tough to replace one-to-one. A possible route is fine sunflower seed flour, but it can react with baking soda and turn green.

It’s harmless, but expect a color change and a slightly different flavor.

In Conclusion

These keto apple muffins bring the best of both worlds: classic apple-cinnamon comfort and smart, low-carb ingredients. They’re easy to bake, freezer-friendly, and endlessly customizable. Keep a batch on hand for quick breakfasts, snack breaks, or a cozy treat that fits your goals. With the right balance of flavor and texture, you won’t miss the coffee shop version at all.
