How to Make a Pumpkin Spice Mug Cake in 5 Minutes

Step 1: Mix the Dry Ingredients

1. Grab a microwave-safe mug (12 oz or larger).
2. Add flour, sugar, baking powder, pumpkin pie spice, and salt.
3. Stir with a spoon until well combined.

Step 2: Stir in the Wet Ingredients

4. Add pumpkin puree, milk, oil (or melted butter), and vanilla.
5. Mix until the batter is smooth and thick.

Texture Tip: If it looks runny, sprinkle in a bit more flour. If too thick, add a splash more milk.

And Step 3: Microwave and Cool

6. Microwave on high for 60–70 seconds.
7. Check with a toothpick. If it comes out mostly clean, it’s done. If not, zap it in 10-second bursts.
8. Let sit for 1–2 minutes to cool slightly and finish cooking.

Step 4: Add Toppings (Optional, but Highly Recommended!)

• Whipped cream or coconut whip
• Sprinkle of cinnamon or nutmeg
• Maple syrup drizzle
• Crushed graham crackers or cookies
• Vanilla or cream cheese glaze

Tips for the Perfect Mug Cake

• Don’t overmix – Stir just until combined.
• Use pumpkin puree, not pumpkin pie filling.
• Microwaves vary – Start with 60 seconds and adjust as needed.
• Use a big enough mug – Leave room for the cake to rise.
