kcalThis moist and fluffy keto pumpkin spice cake is loaded with warm fall spices and made with almond flour. It’s the perfect low-carb dessert for Thanksgiving, Halloween, or any autumn gathering with just 4g net carbs per slice.
Ingredients
2.5 cups blanched almond flour
1 cup pumpkin puree
3/4 cup granulated erythritol
4 large eggs
1/2 cup butter
2 teaspoons pumpkin pie spice
1 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
2 teaspoons vanilla extract
1/4 cup heavy cream
1/2 cup chopped pecans
Directions
- Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan or 9×9-inch square baking pan with butter or line with parchment paper.
- Whisk together the dry ingredients in a large bowl: almond flour, erythritol, pumpkin pie spice, baking powder, baking soda, and salt until well combined.
- Mix the wet ingredients in a separate bowl by whisking together the eggs, pumpkin puree, melted butter, vanilla extract, and heavy cream until smooth.
- Combine wet and dry ingredients by pouring the wet mixture into the dry ingredients and gently folding with a spatula just until no dry streaks remain. Do not overmix.
- Pour the batter into your prepared pan and smooth the top with a spatula. Sprinkle with chopped pecans if using.
- Bake for 40-45 minutes or until a toothpick inserted into the center comes out with just a few moist crumbs attached.
Notes
- Make sure to use pure pumpkin puree, not pumpkin pie filling which contains added sugars.
- Room temperature eggs incorporate better and create a fluffier texture.
- Store leftovers covered in the refrigerator for up to 5 days or freeze for up to 3 months.
- For a dairy-free version, substitute the butter with coconut oil and use coconut cream instead of heavy cream.
- Net carbs are calculated by subtracting fiber from total carbs. Erythritol is not included in the carb count as it does not impact blood sugar.

Tips for Perfect Keto Pumpkin Spice Cake Every Time
Making this cake is straightforward, but a few key techniques will ensure it turns out perfectly every time. First, let’s talk about ingredient temperature and mixing methods. Then, we’ll cover storage tips to keep your cake fresh and flavorful.
Choose the Right Pumpkin Puree
Always use pure pumpkin puree, not pumpkin pie filling which contains added sugars and spices. Look for canned pumpkin with only one ingredient listed on the label. However, if you prefer making your own from fresh pumpkin, just make sure to drain any excess moisture by pressing it through cheesecloth first.
Measure Your Almond Flour Correctly
Almond flour can be tricky because it packs down easily. For best results, spoon it into your measuring cup and level it off with a knife. Never scoop directly from the bag as this compacts the flour and can make your cake dense. In addition, using finely blanched almond flour rather than almond meal gives you a lighter, more cake-like texture.
Don’t Overmix the Batter
Once you add the dry ingredients to the wet ingredients, mix just until combined. Overmixing develops the proteins in the eggs and can result in a tough, rubbery texture. Therefore, use a gentle folding motion and stop as soon as you no longer see dry streaks of flour.
Test for Doneness Properly
Keto cakes can be tricky to gauge because they often look done on top before the center is fully baked. Insert a toothpick into the center of the cake. It should come out with just a few moist crumbs attached, not wet batter. As a result, your cake will be perfectly moist without being underbaked.
Let It Cool Completely
This step is crucial for texture. Allow the cake to cool in the pan for 15 minutes, then turn it out onto a wire rack to cool completely. Cutting into a warm cake can cause it to fall apart or become gummy. Therefore, practice patience and wait at least an hour before frosting or serving.
Delicious Ways to Customize Your Cake
One of the best things about this recipe is how adaptable it is to different preferences and dietary needs. For example, you can easily swap sweeteners, adjust spice levels, or make it dairy-free. Let me walk you through some of my favorite variations.
Make It Dairy-Free
Simply replace the butter with coconut oil and use full-fat coconut milk instead of heavy cream if your frosting calls for it. The cake itself is already naturally dairy-free if you use coconut oil from the start. However, make sure all your ingredients are certified dairy-free if you have severe allergies.
Switch Up Your Sweetener
While I prefer erythritol-based sweeteners for their clean taste, you can use monk fruit sweetener or allulose instead. Each sweetener has slightly different sweetness levels, so adjust to taste. For best results, I recommend powdered sweetener blends designed for baking as they dissolve smoothly and don’t leave a gritty texture.
Add a Cream Cheese Frosting
Transform this simple cake into an impressive layer cake by adding a sugar-free cream cheese frosting. Beat together softened cream cheese, butter, powdered sweetener, and vanilla until fluffy. This pairs beautifully with the warm spices and creates a dessert worthy of any celebration. In addition, you can check out my keto pumpkin cheesecake recipe for more cream cheese dessert inspiration.
Make It Into Cupcakes
Divide the batter among lined muffin tins and reduce the baking time to about 20-25 minutes. Cupcakes are perfect for portion control and make serving at parties much easier. Therefore, this variation is ideal for holiday gatherings where guests can grab and go.
Boost the Spice Level
If you love extra-spicy desserts, increase the cinnamon by half a teaspoon and add a pinch of ground cloves. You can also fold in sugar-free chocolate chips or chopped pecans for added texture. However, remember that add-ins will slightly change the nutrition facts per serving.
Try Other Pumpkin Desserts
If you’re enjoying pumpkin season as much as I am, you’ll want to try my classic keto pumpkin pie and these adorable soft pumpkin cookies. Both recipes use similar ingredients and capture that cozy autumn flavor we all love.
Understanding the Nutrition Behind This Cake
Each slice of this keto pumpkin spice cake contains approximately 220 calories, making it a satisfying dessert that won’t break your daily macros. The majority of those calories come from healthy fats, which is exactly what you want on a ketogenic diet. In addition, you’ll get about 6 grams of protein per serving from the eggs and almond flour.
The net carb count sits at just 4 grams per slice, which is remarkably low for a cake this size and flavor. This is achieved by using almond flour instead of wheat flour and sugar-free sweeteners instead of regular sugar. Therefore, you can enjoy a generous portion without worrying about getting kicked out of ketosis.
Pumpkin itself is a nutritious ingredient that provides important vitamins and minerals while remaining relatively low in carbs. The fat content of about 20 grams per slice comes primarily from the almond flour, eggs, and butter. These are all wholesome ingredients that support the principles of a well-formulated ketogenic diet.
The fiber content of 2 grams per serving helps with digestion and contributes to that satisfying, full feeling after eating. As a result, one slice is usually enough to satisfy your sweet tooth completely. However, if you’re following a stricter keto plan with very low carb limits, you can cut smaller slices and adjust the nutrition accordingly.
Your Pumpkin Cake Questions Answered
Over the years, I’ve received tons of questions about making keto cakes, especially during the fall season. Below, I’ve compiled the most common questions about this recipe along with detailed answers to help you achieve perfect results every time.
Can I use coconut flour instead of almond flour?
Coconut flour absorbs much more liquid than almond flour, so you cannot substitute it 1:1. If you want to use coconut flour, you’ll need to use only about 1/3 of the amount and add extra eggs. However, the texture will be different from the original recipe.
How do I store leftover pumpkin spice cake?
Store the cake in an airtight container in the refrigerator for up to 5 days. You can also freeze individual slices wrapped tightly in plastic wrap and aluminum foil for up to 3 months. Thaw in the refrigerator overnight before serving.
Can I make this cake ahead of time?
Yes, this cake actually tastes better the next day as the flavors have time to meld together. Bake it up to 2 days ahead and store it covered in the refrigerator. Bring it to room temperature before serving or warm individual slices in the microwave for 15-20 seconds.
Why is my keto cake dense and heavy?
Dense texture usually comes from overmixing the batter or using too much almond flour. Make sure you’re measuring your flour correctly by spooning it into the cup rather than scooping. Also, mix the batter just until combined and avoid overbeating.
Can I make this without eggs?
Eggs provide crucial structure and moisture in this recipe, so removing them entirely is challenging. You can try using flax eggs (1 tablespoon ground flaxseed mixed with 3 tablespoons water per egg), but the texture will be different and the cake may be more crumbly.
What can I use instead of pumpkin puree?
Sweet potato puree or butternut squash puree work well as substitutes, though they will slightly change the flavor profile. Make sure whatever you use is unsweetened and has a similar thick consistency to pumpkin puree.
