3 MINUTE BUTTERSCOTCH CHOCOLATE CHIP CAKE IN A MUG

I've posted several recipes for Cake in a Mug that are perfect treats for one while Sheltered-in-Place. Here's another -- Butterscotch Chocolate Chip Cake in a Mug! Of course, the assumption is that you have butterscotch pudding powder in your pantry. If you don't, do you have another pudding? I have Bird's Custard, and I'm going to try that. You can always make Butterscotch Pudding from scratch, if you don't have a box.

Butterscotch Chocolate Chip Cake in a Mug

Ingredients
1 egg
3 tablespoons milk
3 tablespoons Canola oil
1/8 teaspoon pure vanilla extract
1/8 teaspoon baking powder
4 tablespoons light brown sugar
2 tablespoons instant butterscotch pudding powder
4 tablespoons all purpose flour
2 tablespoons mini bittersweet chocolate chips

Directions
Prepare mug by coating the inside lightly with cooking spray (or melted butter).
Pour dry ingredients into bowl.
Beat egg first with spoon and mix in other liquid ingredients.
Add dry ingredients and mix until you’ve removed all lumps.
Fold in chocolate chips.
Pour batter into mug (don't fill more than halfway) and smooth top with spoon.
Thump mug firmly on table several times to remove excess air bubbles.
Place mug on top microwaveable small plate or saucer.
Bake in microwave for 3-4 minutes. Check for doneness by inserting toothpick in middle of microwave mug cake. If toothpick is dry, mug cake is done.
Wait two minutes, then run butter knife along inside mug and tip cake onto plate.
