How to Make This Keto Pumpkin Mug Cake
Before starting, gather all your ingredients and lightly grease your mug to ensure a smooth release after cooking. Now let’s dive into this cozy creation!
Step 1: Melt the Butter
Place 1 tbsp of butter into your mug and microwave for about 20 seconds until melted. Swirl the mug to coat the inside—this prevents sticking and keeps your cake fluffy on all sides.
Step 2: Mix the Dry Ingredients
Add 2 tbsp almond flour, ½ tsp pumpkin spice, ½ tsp baking powder, and 1 to 1.5 tbsp sweetener to the mug.
Stir gently to blend the dry ingredients well.
Step 3: Add Wet Ingredients
Now, mix in 2 tbsp pumpkin puree, 1 large egg, and ¼ tsp vanilla extract. Stir thoroughly until the mixture becomes smooth and well-blended.
The pumpkin gives this mug cake a rich, creamy body and natural sweetness.
Using a flax-egg? Combine 1 tbsp ground flaxseed with 2.5 tbsp water, let sit 5 minutes, and add in place of the egg.
Step 4: Microwave and Enjoy
Microwave your mixture for 75–90 seconds, depending on your microwave’s strength. The top should look set and slightly spongy—avoid overcooking to keep it moist and soft.
Serving Suggestions
- Top with sugar-free whipped cream or a dollop of keto cream cheese frosting
