Why You’ll Love This Mug Brownie

  • Quick and easy to make in just 3 minutes.
  • Uses simple pantry ingredients you likely have on hand.
  • No need for an oven, just a microwave.
  • Perfect single-serving size to curb cravings.
  • Customizable with your favorite toppings or mix-ins.

Ingredients You’ll Need

For this simple mug brownie, you’ll need just a handful of ingredients that are likely already in your pantry.

  • 3 tablespoons ground oats – adds texture and a bit of fiber.
  • 1 large egg – binds everything together.
  • 2 tablespoons unsweetened cocoa powder – for that deep chocolate flavor.
  • 2 tablespoons honey or preferred sweetener – to sweeten things up.
  • 2 tablespoons milk of choice – helps create a smooth batter.
  • 1/2 teaspoon baking powder – gives the brownie a bit of rise.
  • Pinch of salt – enhances all the flavors.

Instructions

Step 1: Whisk the Wet Ingredients

In a large mug, whisk together the egg, honey, and milk until you have a smooth mixture. This helps to combine all the flavors nicely.

Step 2: Add Dry Ingredients

Add the cocoa powder, ground oats, baking powder, and salt into the mug. Stir vigorously until everything is well combined and no dry streaks are visible.

Step 3: Cook in the Microwave

Place the mug in the microwave and cook on high for 2-3 minutes. Watch closely for the brownie to rise and the center to set.

Step 4: Let It Rest and Enjoy

Allow the mug brownie to rest for 1 minute after microwaving. This lets the steam finish cooking the center. Enjoy it straight from the mug while it’s warm and gooey.

Tips for Success

  • Use a large, 12-ounce mug to prevent overflow.
  • Stir thoroughly to avoid unpleasant pockets of dry ingredients.
  • Start checking the brownie at 90 seconds to ensure it doesn’t overcook.
  • Letting it rest for a minute improves the texture.

Ingredient Substitutions

  • Quick oats can be used if you pulse them in a blender.
  • A flax egg can replace the egg for a vegan option.
  • Maple syrup or agave can substitute for honey.

How to Store and Reheat

Refrigerator

Cover the mug with plastic wrap and store in the refrigerator for up to two days.

Freezer

Freezing is not recommended as it alters the texture.

Reheating

Reheat in the microwave for 20 seconds to regain its warmth and softness.

Frequently Asked Questions
