2 graham crackers
1 Tbsp melted butter
1 egg
2 oz cream cheese
2 Tbsp sour cream (or yogurt)
2 Tbsp sugar
1 tsp vanilla
1 coffee mug
Crush the two graham crackers. You can use a plastic baggie (or whatever you like) to keep the mess contained.
Butter your mug as you would a cake pan.
Pat the crushed graham cracker base into the bottom of the mug and pour the melted butter over it.
In a separate bowl, beat the egg.
Mix in the cream cheese with the egg. You can use an electric mixer to get the consistency smooth, or soften the cream cheese slightly in the microwave.
Add sour cream (or yogurt) and mix.
Now add the sugar and vanilla and mix well, taking care not to overwork the mixture too much.
Pour the mixture on top of the graham cracker base.
Cook on high (at 1000 watts) for 60 seconds, or until top of cake is set. The cake should appear dry at the edges, feel firm yet springy, and be pulling away from the mug slightly when it is done.
Allow cake to cool and carefully remove it from the mug. Put it in the refrigerator to chill for 1 hour.
