Preheat oven to 400 degrees Fahrenheit. Grease or line a muffin tin and set aside.

In a small bowl, combine all topping ingredients and mix to a fine consistency. Set aside.

Combine parve milk and vinegar and allow to stand for five minutes (mixture will thicken to a buttermilk consistency).

In a medium-sized bowl, whisk together flour, sugar, baking powder, and salt. Add oil, pareve milk mixture, egg, and extract. Mix well. Fold in cranberries.

Fill each muffin tin three-quarters full (approximately one heaping tablespoon of batter). Top with one tablespoon of crumb topping. Bake for 22-25 minutes, until firm.
