What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 3 tablespoons pumpkin puree
  • 4 tablespoons all-purpose flour
  • 2 tablespoons brown sugar
  • 1 tablespoon vegetable oil
  • 0.5 teaspoon pumpkin pie spice
  • 0.25 teaspoon baking powder

Step by step instructions

Step 1: Combine Wet Ingredients

In a large microwave-safe mug add pumpkin puree, vegetable oil, and brown sugar then stir until the sugar is fully dissolved and mixture is smooth.

Step 2: Add Dry Ingredients

Add flour, pumpkin pie spice, and baking powder to the mug and stir gently until just combined being careful not to overmix the batter.

Step 3: Microwave the Cake

Microwave on high for 90 seconds until the top of the cake looks set and springs back lightly when touched. Add 15 seconds if center appears wet.

Step 4: Rest and Serve

Allow the mug cake to cool for 1 minute then top with a dollop of whipped cream and a pinch of cinnamon before serving.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • pumpkin pie spice → a mix of cinnamon nutmeg and ginger in equal parts
  • vegetable oil → coconut oil for a subtle tropical note

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Using pumpkin pie filling instead of plain pumpkin puree which makes the cake too sweet
  • Skipping the resting time and burning your mouth on the very hot mug
