In a small mixing bowl, whisk together peanut butter powder, cocoa powder, zero calorie sweetener and baking powder.
Stir in egg substitute, unsweetened almond milk and vanilla until dry ingredients are completely absorbed and mixture is thoroughly combined.
Lightly spray a microwave-safe mug or ramekin (about 8-10 ounces) with nonstick baking spray. Pour or spoon mixture into prepared mug or ramekin.
Microwave on HIGH for 45 seconds, then check to see if cake is set and lightly springs back when touched. If not set, cook in 15 second increments until done.
Enjoy cake directly in the mug or remove to a small plate. Top with fresh berries, lite whipped topping and/or sprinkles if desired.
Notes
Serving size: 1 chocolate mug cake (entire recipe)WW Points: 2Check the WW Points for this recipe and track it in the WW app. (Must be logged into WW on a smartphone or tablet.)3PointsPlus (Old plan)Air Fryer MethodIf you have an extra 10 minutes and want a noticeably better texture, the air fryer is worth it. Prepare the batter exactly as above, pour into a lightly greased oven-safe ramekin, and use the Bake function at 350°F for 10 minutes. I check mine at the 5-minute mark just to be safe. The result is fluffier and moister than the microwave version—more like an actual cake.(Note: cooking times may vary by air fryer model. My Cosori TurboBlaze works perfectly at these settings.)Tips for Success
Don't overcook. This is the most important tip. Start at 45 seconds and check — overcooking is irreversible and ruins the texture completely.
Use a large enough mug. The batter expands while cooking. An 8–10 ounce mug or ramekin gives it room to rise without overflowing.
Mix in a bowl, not the mug. It's much easier to get the batter fully combined in a small bowl first, then pour it in. Mixing directly in the mug tends to leave dry pockets at the bottom.
Want a little more indulgence? Stir in a teaspoon of mini chocolate chips before microwaving, or add a pinch of espresso powder to deepen the chocolate flavor. A pinch of cinnamon is also surprisingly good.
