This is a single-serving mug cake with the flavors of a pumpkin spice latte. Almond flour and coconut flour make the cake, pumpkin puree and pumpkin pie spice give it the fall flavor, and a tablespoon of coffee or espresso adds the latte taste. Everything is stirred together in one microwave-safe mug and cooked in 60 to 90 seconds.

Save this recipe for later:

Prep is 5 minutes and cooking is about 1 minute, so a warm cake is ready in 6 minutes. The recipe makes 1 serving.

What Goes in the Mug

Amounts are in the recipe card at the bottom. Here is what each one does.

  • Almond flour (3 tablespoons): the low-carb base. It adds moisture and a nutty flavor.
  • Coconut flour (1 tablespoon): absorbs moisture for a lighter, fluffier texture. A little goes a long way.
  • Pumpkin puree (1 tablespoon): the seasonal flavor, and it adds moisture.
  • Sweetener of choice (1 tablespoon): stevia, erythritol or another low-carb option.
  • Baking powder (1/4 teaspoon): helps the cake rise so it is not dense.
  • Pumpkin pie spice (1/4 teaspoon): usually a blend of cinnamon, nutmeg and ginger.
  • Large egg (1): binds the batter and gives the cake structure.
  • Milk or dairy alternative (2 tablespoons): keeps the cake moist. Almond or coconut milk works.
  • Coffee or espresso (1 tablespoon): gives the cake its latte flavor.
Keto Pumpkin Spice Latte Mug Cake – Key Ingredients

Mixing and Microwaving

In a microwave-safe mug, stir together the almond flour, coconut flour, pumpkin puree, sweetener, baking powder and pumpkin pie spice. Add the egg, milk and coffee and mix until smooth. Microwave on high for 60 to 90 seconds, until the cake has risen and is cooked through, then let it cool for a minute.

Getting It Right

  • Watch the microwave. Microwaves vary. Start with 60 seconds and check. The cake should be firm to the touch and well risen. If it needs more time, go in 10-second steps, because overcooking dries it out.
  • Use room temperature ingredients. A room-temperature egg and milk give a smoother batter.
  • Measure the dry ingredients ahead. Then all that is left is to mix and microwave.
  • Eat it fresh. It is at its best straight out of the microwave, with a fluffy, moist texture. It can be covered and kept in the refrigerator for a day, then reheated in the microwave for a few seconds.

Ways to Change It

  • Nuts: add a tablespoon of chopped walnuts or pecans to the batter, or scatter some on top.
  • Chocolate: add a tablespoon of unsweetened cocoa powder, or a few sugar-free chocolate chips.
  • Dairy-free: use coconut milk or almond milk and a dairy-free sweetener.
  • Different spices: use a mix of cinnamon and ginger instead of pumpkin pie spice, with a pinch of nutmeg if you like.
  • Toppings: whipped coconut cream or a dollop of Greek yogurt.

Toppings and Serving

Whipped cream is the simplest topping, and sugar-free whipped cream keeps it keto-friendly. A sprinkle of cinnamon, chopped pecans or walnuts, or a drizzle of sugar-free caramel or chocolate sauce all go well with the pumpkin spice. Because the cake is based on a latte, a hot cup of coffee or espresso next to it is a natural pairing.

FAQ

Can I make it vegan?

Replace the egg with a flax egg or unsweetened applesauce, and use a plant-based milk.

Is there a substitute for almond flour?

Sunflower seed flour works if you have a nut allergy or no almond flour. It has a similar texture, though the flavor may shift slightly.

How can you tell when it is done?

It has risen and is firm to the touch. If it is not quite set after 60 to 90 seconds, give it another 10 seconds. Overcooking makes it dry.
