Mix chocolate sauce ingredients in a microwave safe bowl, microwave for 30 seconds. Mix well and set aside.
Mix all cake ingredients in a microwave safe bowl or jar. This is the bowl or jar you will eat it in. It is a single serving so the bowl or jar should hold about 8 ounces. Microwave on high for 45 seconds.
Top with the mini marshmallows. Microwave 30 more seconds. All microwaves vary so you may need to adjust cooking time. It’s better to cook less than more because overcooking will lead to a tough textured cake.
Top with crushed graham crackers and chocolate sauce.
Allow to cool a few minutes so you don't get burned, but then devour in the bowl or jar you made it in!
Microwaves vary so make sure you do not over cook. The cake is meant to be gooey and chocolaty, not like a firm traditional cake. If you overcook it, the marshmallows will get too tough to eat.
If you cannot eat nuts, you can also replace the almond butter with sunflower seed butter or a non bitter tahini. Or you can simply remove it all together. Your cake will be more gooey like fudge, and less cakey, but still delicious.
This can serve 1-2 people, depending on how much dessert you want
