Ingredients

  • 1 large egg

  • 1 scoop (30-35g) chocolate protein powder (whey-casein blend or plant-based blend works best for texture)

  • 1 tablespoon (8g) unsweetened cocoa powder

  • 1 tablespoon (15ml) maple syrup or sugar-free syrup (like monk fruit)

  • ½ teaspoon baking powder

  • 1-2 tablespoons (15-30ml) milk of choice (any dairy or unsweetened almond milk)

  • Pinch of salt

  • Optional Add-ins:

    • 1 tbsp dark chocolate chips

    • ½ tsp vanilla extract

    • A dash of instant coffee (enhances chocolate flavor)

    • For topping: Greek yogurt, nut butter, a sprinkle of sea salt, or fresh berries

Equipment Needed

  • 1 microwave-safe mug (12 oz / 350ml capacity minimum)

  • 1 small whisk or fork

  • 1 measuring spoon set

Step-by-Step Instructions

Step 1: Combine Dry Ingredients

In your mug, add the scoop of protein powder, cocoa powder, baking powder, and a pinch of salt. Use your fork to whisk them together thoroughly. This ensures no clumps of baking powder and even chocolate distribution.

Step 2: Add Wet Ingredients

Crack the egg directly into the mug with the dry ingredients. Add the maple syrup. Begin mixing with your fork. The batter will be very thick and pasty at first—this is normal.

Step 3: Achieve the Perfect Batter

Slowly add 1 tablespoon of milk and continue to mix vigorously. Aim for a smooth, thick, but pourable brownie-batter consistency. If it’s still too thick or pasty, add the second tablespoon of milk, one teaspoon at a time. Be careful not to add too much milk, or the cake can become rubbery. If using, stir in chocolate chips or vanilla extract now.

Step 4: Microwave to Perfection

Clean the rim of your mug with a finger or paper towel to ensure even rising. Place the mug in the center of the microwave.

  • Microwave on high for 60 seconds. Start checking at 60 seconds—the top should look set, and it will have risen.

  • If the center still looks very wet, microwave in additional 15-second bursts. Do not exceed 90 seconds total for a standard 1100W microwave. Over-microwaving is the #1 cause of dry, rubbery mug cakes. The cake will continue to set as it cools.

Step 5: Cool & Serve

Carefully remove the mug (it will be hot!). Let it cool for 1-2 minutes. It will sink slightly as it cools. Enjoy directly from the mug!

  • Topping Idea: While warm, top with a dollop of Greek yogurt or a drizzle of almond butter for added creaminess and protein.
