What You’ll Need

For the Crisp Topping:
- 3 tablespoons (1 1/2 oz/45g) butter, melted
- 4 tablespoons oats
- 2 tablespoons chopped pecans (or walnuts for a substitute)
- 2 tablespoons all-purpose flour
- 2 tablespoons brown sugar
- ¼ teaspoon cinnamon
- ⅛ teaspoon salt
For the Apple Filling:
- 1 small apple, peeled and diced (Granny Smith or Honeycrisp work well)
- ½ tablespoon all-purpose flour
- ½ tablespoon brown sugar
- ¼ teaspoon cinnamon

How to Make It

Prepare the Crisp Topping: In a small bowl, combine the oats, flour, pecans, brown sugar, cinnamon, and salt. Stir in the melted butter until the mixture is crumbly and well combined.
Toss the Apples: In another bowl, toss the diced apple with the ½ tablespoon flour, ½ tablespoon brown sugar, and ¼ teaspoon cinnamon until evenly coated.
Assemble in the Mug: Fill a microwave-safe mug with the apple mixture (it’s okay to fill it up as the apples will cook down). Spoon the crisp topping evenly over the apples.
Microwave: Microwave on high for 2 to 2 ½ minutes, or until the apples are bubbling and the topping is golden. (Cooking time may vary based on your microwave’s wattage and the mug’s size.)
Cool and Serve: Carefully remove the mug from the microwave (it will be very hot!) and let it cool for a few minutes. Enjoy warm, ideally with a scoop of vanilla ice cream.

Perfect Pairings: Toppings and Serving Ideas

Take your Microwave Mug Apple Crisp to the next level with a scoop of vanilla ice cream or a dollop of whipped cream. For a drizzle of sweetness, try caramel sauce or maple syrup. If you’re feeling fancy, sprinkle a pinch of sea salt on top for a delightful contrast. These additions make this cozy dessert even more indulgent!

Quick Storage and Reheating Tips

If you have leftovers (though it’s hard to resist!), let the mug cool completely, then cover it with plastic wrap or a lid. Store in the fridge for up to 2 days. To reheat, microwave for 30-45 seconds until warm. Add a fresh scoop of ice cream or whipped cream to bring it back to life!

Fun Recipe Variations to Try

Switch things up by using pears instead of apples or adding raisins or dried cranberries for extra sweetness. For a nut-free version, skip the pecans and add sunflower seeds or extra oats. You can also experiment with spices like nutmeg or cardamom for a unique twist. The possibilities are endless!

Microwave Mug Tips for Success

Use a microwave-safe mug that’s at least 12 ounces to prevent overflow as the apples cook down. Avoid mugs with metallic accents, as they can cause sparks. If your microwave is less powerful than 1200W, start with 2 ½ minutes and adjust as needed. Always handle the mug with care—it’ll be hot!
