🥧 Ingredients for this keto pumpkin spice cake recipe

For the cake

2 ¾ cups almond flour
1 ½ cups powdered erythritol
2 tablespoons pumpkin pie spice
2 teaspoons gluten-free baking powder
½ teaspoon salt
6 large eggs
1 cup pumpkin puree
½ cup Pacific Foods Unsweetened Hemp Beverage
1 tablespoon vanilla extract

For keto cream cheese frosting

1 8oz block cream cheese, room temperature
1 cup powdered erythritol
¼ cup Pacific Foods Unsweetened Hemp Original Beverage

Ingredient substitutions

You can swap the original ingredients with these keto alternatives:

Powdered erythritol: You can replace powdered erythritol with another keto-friendly sweetener like powdered swerve or powdered xylitol, powdered stevia, or monk fruit sweetener.
Eggs: You can replace eggs with flax or chia eggs for an egg-free or vegan option.
Unsweetened hemp original beverage: You can substitute it with other keto-friendly, unsweetened plant-based milk like cashew, coconut, or almond milk,
Cream cheese: You can also use keto-friendly cream cheese alternatives made from nuts, like almond or cashew cream cheese.

Note: We don't recommend substituting almond flour with coconut flour as coconut flour is more absorbent, and you would need to adjust all the other ingredients.

Optional toppings

You can use these optional toppings to enhance your dessert experience. Some keto-friendly options are:

Chopped pecans or walnuts
Pumpkin seeds
Sugar-free caramel sauce
Coconut cream

Cooking tools required

To make this Keto Pumpkin Spice Cake recipe, you'll need the following tools:

Large mixing bowl
Medium mixing bowl
Electric hand mixer
10.5" cast iron skillet
Measuring cups and spoons

Tool substitutes list

If you don't have the exact tools mentioned, you can use the following tool substitutes:

Large mixing bowl: You can use any large bowl or pot that can hold all the ingredients for the cake batter. A salad bowl or a large saucepan can work.
Electric mixer: You can use a stand mixer if you don't have an electric mixer. Or you can use a whisk or a fork to mix the ingredients. It may take more time and effort, but it will still get the job done.
10.5" cast iron skillet: Instead of a cast iron skillet, you can use a 9x13-inch baking dish or a similarly sized oven-safe dish. Any oven-safe glass or ceramic baking dish can wok.

Chef's pro tip

When our cake turns out dry and crumbly, it's like a major party foul, right? But no worries, we've got this. Let's kick things off by getting super exact with that almond flour measurement. And hey, show your batter some love—overmixing is just not cool. Our secret weapon? A dash of extra moisture! Something like pumpkin puree or unsweetened hemp milk does the trick. Ready to dig into your uber-moist, spice-hitting-all-the-right-notes, keto pumpkin spice cake? It's about to make your taste buds do a happy dance!

How to make it healthier

A simple way to reduce the calorie content is to omit the frosting altogether. This way, you can indulge in a healthier version of the pumpkin cake while still savoring its delicious flavors.

Time-saving tips

Buy a store-bought pumpkin spice mixture but make sure that it is keto-friendly.
Measure the ingredients beforehand to save time when you're cooking.

What can I prepare ahead of time?

Prepare the cake batter by mixing the wet ingredients the night before and store it in the refrigerator until ready to bake.
You can make a fresh batch of pumpkin spice mix where you can ground spices such as cinnamon, nutmeg, cloves, ginger, and allspice.
The icing can also be prepared in advance and stored in the refrigerator.
