Brownie in a Mug (6 Variations)

Ingredients:

1/4 cup sugar
1/4 cup flour
2 tablespoons cocoa
1 pinch salt
2 tablespoons vegetable oil or 2 tablespoons melted butter
5 tablespoons water
1/4 teaspoon vanilla extract (optional)

Directions:

1. Add all of dry ingredients to mug.
2. Mix well with a fork or small whisk until blended.
3. Add oil or melted butter, water, and vanilla.
4. Mix well (add mix-ins if using).
5. Put in the microwave and cook on high heat for 1 minute 40 seconds - 2 minutes (less time for a more moist brownie, more time for a more cake-like brownie).
6. Add toppings or a scoop of ice cream and enjoy!
7. Variations:.
8. Mounds: add 1-2 tablespoons chocolate chips and a sprinkling of sweetened flaked coconut on top of cooked brownie.
9. Peanut Butter Swirl: add 1-2 tbsp creamy peanut butter into mix before microwaving, or add 1 tablespoons on top of brownie after its cooked (I've noticed the peanut butter swirl tastes best with peanut butter on top of the brownie after it's cooked).
10. Berry Jam: top cooked brownie with 1-2 tablespoons melted berry jam (strawberry, raspberry or blackberry is best. Just heat in microwave until melted then pour over brownie).
11. S'mores: top cooked brownie with mini marshmallows and graham cracker crumbs.
12. Candy Bar: mix in 1-2 tablespoons of your favorite chopped chocolate candy bar into the mix before heating, or add m&ms.
13. Caramel Sea Salt: drop 2 salted caramels into the middle of the mix before heating, and once done top with a light sprinkle of sea salt.
