Mix the peanut butter powder with the water until a smooth paste. Grease 2- 8 ounce- ramekins.
Stir in the remaining ingredients in with the peanut butter powder until well combined.
Evenly pour the batter into the greased ramekins.
Microwave each ramekin for 1 minute then check the center of the cake with a toothpick. If it comes out clean, let cool slightly and enjoy. If it's still slightly wet on the toothpick, microwave for another 20-30 seconds.
To make topping simply add to a stand mixer and blend on high until desired texture or use a hand mixer to whip.
Add desired topping once cake is cool.
To make a layered cake as in the pictures, place some frosting on one cake, then place second cake on top of the other. Add the rest of the topping and enjoy.

Brenda's Notes:

You can bake this in the oven at 350 degrees for about 10-15 minutes or until a toothpick in center comes out clean.
Nutrition info does not include optional topping.
Makes this Nut Free: You can replace the unsweetened almond milk with coconut milk if desired but this will increase the calorie amount. Use sunflower seed butter to replace peanut butter.
To make this layered cake for 2, double the topping recipe.
