It all starts with chocolate protein powder and almond flour because it’s a source of protein too! Then we’re adding almond milk. When we say this one is protein-packed, we mean it. We’re also adding cocoa powder and sugar, a pinch of baking powder to make the cake rise, and vanilla extract for added deliciousness.

Here’s the first PRO tip: Don’t try to mix your ingredients in the mug; that’s a newbie mistake; there’s not enough room to incorporate the ingredients well enough. Use a small mixing bowl to mix the ingredients and then transfer the batter into the mug.

Tip number two: Don’t overfill the mug, or you’ll end up with a chocolatey mess. Fill the mug up to three-fourths of its capacity.

Here’s a question I get often, isn’t the microwave dangerous and radioactive? Radioactive, yes, dangerous, no. Our microwave oven works with electromagnetic waves or radiation that agitates the food molecules’ water to heat it. After over 70 years of people using the microwave worldwide, there are basically no health risks.

Besides, making our mug-cake in the oven as if it were a souffle would be a pain, trust me. You’re better off nuking your cake in the microwave. Let’s get started. You’ll find this cake a very effective incentive to make you go to the gym!
