Ingredients

  • ½ packet of flavored instant oatmeal
  • 1 tablespoon butter melted
  • ¾ cup blueberries fresh or frozen
  • ½ teaspoon cornstarch see note

Instructions

  • In a small bowl with a fork, mix the instant oatmeal and melted butter until it resembles a crumble topping.
  • Add the fresh or frozen blueberries (if using frozen see note!) to the mug; toss with cornstarch if using. I like to fill my mug to the brim with berries, so the amount will vary depending on its size. Spread the topping over the top.
  • Microwave on HIGH 1 ½ minutes. This time will be dependant on your microwave wattage, the size of your mug and quantity of berries used. Continue to microwave in additional 30-second increments until the blueberries are bubbling.
  • Let cool slightly before adding a scoop of vanilla ice cream, if liked. It's so yummy!

Notes

  1. Mugs: Use a microwave-safe mug with enough room for the blueberries to bubble as they cook. I prefer a shorter, broader mug because it gives the topping more surface area.
  2. Blueberries: Fresh or frozen blueberries both work well. Frozen berries do not need to be thawed, but they may require a little additional cooking time.
  3. Cooking Tip: Fill the mug generously with blueberries, as they will soften and shrink in the microwave.
  4. Instant Oats: Maple brown sugar or cinnamon spice instant oatmeal pairs especially well with blueberries.
  5. Cooking Time: Microwave cooking times vary. Begin with the time listed and add a few seconds as needed, until the berries are hot and bubbling.
  6. Texture: The topping will be softer than a traditional oven-baked crisp, with some of the oats settling into the warm blueberry sauce.
    Let the crisp rest briefly before serving, as the berries will be very hot.
