🔪 How to Make Low Carb Pumpkin Cake
To Make the Cake
Preheat oven to 350°F.
Add the almond flour, oat fiber, baking powder, pumpkin pie spice and salt to a mixing bowl. Whisk to combine, then set aside.
In a separate bowl, add in the egg whites and whip up using a hand mixer, then set them aside.
In another bowl, add in the pumpkin puree, sour cream, heavy cream, egg yolks, both sweeteners and the vanilla extract.
Mix using a hand mixer until well combined, then mix in the egg whites.
Add in the dry ingredients and mix just until combined, but don’t over mix.
Pour the mixture into a 9 x 13 baking pan that’s been lined with parchment paper.
Bake for 30 minutes or until the cake has set and a toothpick, when inserted, comes out clean. Allow the cake to cool completely before frosting.
To Make the Frosting
Add the cream cheese and butter into a mixing bowl and whip up with a hand mixer.
Add in the powdered sweetener and vanilla bean paste.
Then continue mixing until well combined and fluffy.
Using an offset spatula, frost the cooled cake.
Slice and serve.
☑️ Storage Instructions
Cover the baking dish with a lid or with a layer of foil and place in the fridge. It should stay fresh for up to 3-4 days.
To freeze it, wrap individual slices or the whole cake tightly in plastic wrap to prevent freezer burn. For extra protection, place the wrapped cake in an airtight container or a freezer bag.
When you're ready to enjoy it, simply remove the cake from the freezer and let it thaw in the refrigerator overnight, or at room temperature for a few hours before serving.
💡 Tips for Making Keto Pumpkin Layer Cake
- For the best texture, make sure your eggs, sour cream, and cream cheese are at room temperature before mixing. This helps create a smoother batter, resulting in a fluffier cake.
- After adding the dry ingredients to the wet ingredients, mix just until combined. Overmixing can lead to a dense cake, so a few lumps are okay.
- Use the spoon-and-level method for measuring almond flour and oat fiber. This ensures you’re not using too much, which can affect the cake's texture.
- Baking times can vary, so use a toothpick to test the cake’s doneness. Insert it into the center; if it comes out clean or with a few crumbs, it’s ready.
- Allow the cake to cool completely before frosting to prevent the cream cheese frosting from melting. This also helps the flavors to settle.
🔄 Substitutions and Additions
- Chocolate Chips: Add sugar-free chocolate chips to the batter for a delicious chocolatey twist.
- Dried Fruits: Add some dried cranberries (low sugar or unsweetened) for a touch of sweetness and texture. Just make sure you allow for the additional carbs.
- Spices: Experiment with adding a dash of nutmeg, cloves, or ginger for extra warmth and depth of flavor.
- Zest: A bit of orange or lemon zest can brighten the flavors of the cake.
Why Did My Cake Turn Out Dense?
Overmixing the batter or not whipping the egg whites properly can lead to a dense cake. Make sure to fold the egg whites gently into the batter and avoid over-stirring once the dry ingredients are added.
Why Did My Cake Sink in the Middle?
A sunken cake can be caused by underbaking, opening the oven door too early, or using too much leavening. Ensure the cake is fully baked by checking with a toothpick, and avoid disturbing it while it's still rising.
Why is My Cake Unevenly Baked?
Uneven baking can occur if your oven has hot spots. Rotate the cake halfway through baking or invest in an oven thermometer to ensure consistent temperature.
Is Pumpkin Keto?
Yes, pumpkin is low in carbs and high in fiber, making it suitable for a Keto or low-carb diet when used in moderation.
Can I Use Fresh Pumpkin Instead of Canned Puree?
Yes, you can use fresh pumpkin puree, but ensure it's cooked and blended until smooth to achieve the right consistency in the batter.
