Keto Pumpkin Cupcakes With Cinnamon Frosting – Cozy, Low-Carb Fall Treats
These cupcakes bring all the warm, spiced comfort of fall without the sugar crash. They’re soft, tender, and full of pumpkin flavor, topped with a fluffy cinnamon-kissed frosting that tastes like a latte on top of a cupcake. If you’re following a low-carb or keto lifestyle, these will hit the spot without breaking your macros.
Even non-keto friends will enjoy them. They’re simple to make, bake up reliably, and store well for make-ahead desserts or snacks.
Ingredients
Method
- Preheat and prep: Heat your oven to 350°F (175°C). Line a 12-cup muffin pan with liners. Lightly mist with nonstick spray to prevent sticking.
- Mix dry ingredients: In a large bowl, whisk 2 cups almond flour, 2 tablespoons coconut flour, 1 tablespoon baking powder, 1/2 teaspoon xanthan gum, 1 teaspoon pumpkin pie spice, and 1/4 teaspoon salt until well combined and lump-free.
- Whisk wet ingredients: In another bowl, whisk 3 large eggs, 3/4 cup pumpkin purée, 1/2 cup granulated keto sweetener, 1/3 cup melted butter, 1/3 cup unsweetened almond milk, and 1 teaspoon vanilla. The mixture should be smooth and glossy.
- Combine: Pour wet ingredients into dry. Stir gently with a spatula until just combined. The batter will be thicker than classic cupcake batter but should be scoopable. If it seems too stiff, add 1–2 tablespoons more almond milk.
- Fill the liners: Divide the batter evenly among the 12 liners, filling each about 3/4 full. Smooth the tops slightly with the back of a spoon for even domes.
- Bake: Bake for 18–22 minutes, until the tops spring back lightly and a toothpick comes out clean or with a few moist crumbs. Avoid overbaking to keep them tender.
- Cool completely: Let cupcakes cool in the pan for 5 minutes, then transfer to a rack to cool fully before frosting. This prevents melting and sliding.
- Make the frosting: Beat 6 ounces softened cream cheese and 1/2 cup softened butter until creamy and fluffy, about 2–3 minutes. Add 1 1/4 cups powdered keto sweetener, 1 teaspoon vanilla, 1 teaspoon ground cinnamon, and a pinch of salt. Beat until smooth and light. If too thick, add 1–2 teaspoons almond milk. If too loose, add a bit more powdered sweetener.
- Frost: Spoon or pipe the frosting onto cooled cupcakes. For a bakery look, use a large round or star tip. Dust with a light sprinkle of cinnamon if you like.
- Set and serve: Chill frosted cupcakes for 15–20 minutes to help the frosting set, then serve at room temperature for the best texture.
Why This Recipe Works
Almond flour and pumpkin purée team up to create a moist, tender crumb that doesn’t feel “diet.” The batter uses a blend of blanched almond flour for structure and coconut flour for extra lift and softness. A touch of xanthan gum helps mimic the elasticity you’d get from gluten, so the cupcakes don’t crumble.
Granulated erythritol or a monk fruit blend provides sweetness without spiking carbs, and the warm spices make every bite taste like fall. The frosting combines cream cheese, butter, and cinnamon for a silky finish that pipes beautifully and sets just enough to hold its shape.
What You’ll Need
- Almond flour (blanched, fine) – for structure and a soft crumb
- Coconut flour – to absorb moisture and add tenderness
- Granulated keto sweetener (erythritol, allulose, or monk fruit blend)
- Pumpkin purée (100% pumpkin, not pumpkin pie filling)
- Eggs – room temperature
- Butter – melted and slightly cooled (or coconut oil for dairy-free cupcakes)
- Unsweetened almond milk (or your favorite low-carb milk)
- Vanilla extract
- Baking powder (aluminum-free preferred)
- Xanthan gum (optional but helpful)
- Salt
- Pumpkin pie spice (or cinnamon, nutmeg, ginger, and cloves)
- Cream cheese – softened
- Butter – softened (for the frosting)
- Powdered keto sweetener (for the frosting)
- Ground cinnamon (for the frosting and optional dusting)
- Vanilla extract (for the frosting)
- Pinch of salt (for the frosting)

How to Store
Store frosted cupcakes in an airtight container in the fridge for up to 5 days. For the best flavor and texture, let them sit at room temperature for 15–20 minutes before serving.
Unfrosted cupcakes can be wrapped and frozen for up to 2 months. Thaw overnight in the fridge, then frost fresh. Keep the frosting covered and chilled; it will stay smooth for about a week.
Benefits of This Recipe
- Keto-friendly and low in sugar: Uses low-carb sweeteners and nut flours to keep carbs in check.
- Moist, tender texture: Pumpkin adds natural moisture, so the cupcakes don’t feel dry or crumbly.
- Satisfying fats: Butter, cream cheese, and almond flour help keep you fuller longer.
- Warm, familiar flavors: Cinnamon and pumpkin spice make it a crowd-pleaser, even for non-keto eaters.
- Make-ahead friendly: Cupcakes and frosting both store well, perfect for parties and meal prep.
Common Mistakes to Avoid
- Using pumpkin pie filling: It contains sugar and spices already.
Always choose pure pumpkin purée.
- Overbaking: Keto batters can dry out quickly. Start checking at 18 minutes.
- Skipping room-temperature ingredients: Cold eggs and cream cheese can cause lumpy batter and frosting.
- Packing the almond flour: Fluff it, then spoon and level. Too much flour makes dense cupcakes.
- Ignoring sweetener type: Some sweeteners are sweeter than others.
Taste the batter and adjust if needed.
Variations You Can Try
- Pecan crunch: Fold 1/3 cup chopped toasted pecans into the batter for texture.
- Maple vibe (keto-style): Add 1/2 teaspoon maple extract to the frosting for a cozy twist.
- Dairy-free: Use coconut oil in the cupcakes and a dairy-free cream cheese and butter substitute for the frosting.
- Chocolate chip pumpkin: Stir in 1/3 cup sugar-free dark chocolate chips for a mocha-pumpkin feel.
- Extra spice: Add an extra 1/2 teaspoon cinnamon or a pinch of cardamom for a bolder spice profile.
FAQ
Can I make these cupcakes without coconut flour?
Yes, but you’ll need to adjust. Replace the 2 tablespoons coconut flour with an additional 1/3–1/2 cup almond flour, adding a bit more if the batter seems loose. Coconut flour absorbs more liquid, so without it, you’ll rely on almond flour for thickness.
What’s the best sweetener for these cupcakes?
Use a granulated erythritol or monk fruit blend for the batter and a powdered version for the frosting.
Allulose works too, but it can brown faster and make the cupcakes slightly softer, so keep an eye on bake time.
Can I make them egg-free?
Keto batters depend on eggs for structure. A flax or chia egg may work, but the texture will be denser and more fragile. If you try it, let the cupcakes cool fully before removing from the liners.
How do I keep the frosting from being grainy?
Use powdered sweetener, not granulated.
If you only have granulated, blitz it in a blender until powdery. Also, beat the butter and cream cheese until very smooth before adding sweetener.
Do I need xanthan gum?
No, but it helps. Without it, the cupcakes may be a bit more crumbly.
If skipping, handle gently and let them cool completely before frosting.
Can I make a cake instead of cupcakes?
Yes. Pour the batter into an 8-inch round pan lined with parchment and bake for 25–32 minutes, checking for doneness. Cool fully, then frost.
In Conclusion
Keto Pumpkin Cupcakes with Cinnamon Frosting bring all the cozy flavors you want in a fall dessert, minus the sugar and heaviness.
They’re simple, reliable, and impressive enough for a holiday spread. With a moist crumb and creamy frosting, they stand up to any classic cupcake. Keep a batch on hand for a quick treat or share them at your next gathering.
Chances are, no one will guess they’re low-carb—just that they’re delicious.
