The most delicious Pumpkin Spice Mug Cake — a single-serving fall favorite you can make in under 2 minutes. Gluten-free, dairy-free and paleo-friendly, this quick pumpkin cake delivers big flavor with minimal effort.

It’s pumpkin spice season, and if you love cozy, autumnal flavors, this Pumpkin Spice Mug Cake is a must-try. Perfect for when you want a warm dessert without turning on the oven, this recipe combines pumpkin puree, warming spices, and a tender almond-coconut flour base to create a moist, flavorful single-serving cake. It’s lighter than many traditional mug cakes because it avoids refined flours and sugars, making it a healthier, quick dessert option for busy evenings or impromptu cravings.
Mug cakes are the ideal lazy-girl treat — or lazy-person treat — for nights when you’re settling in to watch a show and suddenly crave something sweet. You don’t need to bake a full pan or pull out fancy equipment. Mix the simple ingredients in a microwave-safe mug or ramekin, microwave for just under two minutes, and you’ve got cake. Top with whipped cream or a scoop of ice cream if you like, but the cake is delicious on its own.

Ingredients You’ll Need
- Almond flour – a flavorful gluten-free, low-carb flour that keeps the cake moist. Substitute any gluten-free flour or use all-purpose flour in place of both almond and coconut flours if not following a gluten-free diet.
- Coconut flour – used in a small amount to lighten the texture. Coconut flour soaks up moisture, so it balances the denser almond flour.
- Pumpkin puree – adds moisture, flavor, and the signature pumpkin taste.
- Maple syrup – a natural sweetener that complements pumpkin and warm spices. Use a low-carb sweetener for a keto version (see notes).
- Coconut oil – melt before adding. You can substitute melted butter or neutral vegetable oil if preferred.
- Egg – helps the cake rise and bind the ingredients.
- Vanilla extract – adds depth and sweetness.
- Spices – a mix of cinnamon, pumpkin pie spice, and a pinch of nutmeg makes this cake distinctly autumnal.

How to Make Pumpkin Spice Mug Cake
This recipe is incredibly simple and perfectly portioned for one. Add the dry ingredients to a microwave-safe coffee mug or ramekin and mix until evenly combined. Then add the wet ingredients — melted coconut oil, maple syrup, pumpkin puree, vanilla, and the egg — and stir until smooth and lump-free. Microwave on high for about 1 minute 35 seconds. Microwaves vary, so you may need a few seconds more or less; the cake should be set but still moist.
For best results, measure directly into the mug and mix thoroughly. The end result is a fluffy, moist single-serving cake that’s fast, comforting, and easy enough for kids to help make. Serve with a dollop of whipped cream, a scoop of ice cream, or a sprinkle of cinnamon sugar.
Can I Make This in the Oven?
If you prefer baking, this recipe can be made in an oven-safe mug or small ramekin. Bake at 350°F (175°C) for about 12–15 minutes, or until a toothpick inserted into the center comes out clean. Baking produces a slightly firmer crumb but still yields a delicious single-serving pumpkin treat.

Make this Keto / Low Carb
To make a low-carb or keto-friendly version, substitute the maple syrup with a granular or liquid low-carb sweetener of your choice (erythritol-based sweeteners or monk fruit blends work well). Keep the almond and coconut flours, and adjust sweetness to taste. The texture will remain tender and satisfyingly cake-like without the added sugars.
