Ingredients for Boozy Whiskey Apple Crisp

- For the Apple Whiskey Filling:
- 2 lbs (32 oz/907 g) Granny Smith apples (about 5 medium apples, peeled, cored, and sliced ¼-inch thick)
- ½ cup (3 oz/85 g) dark brown sugar
- 2 tablespoons all-purpose flour
- 1 teaspoon cinnamon
- 3 tablespoons O’Driscolls Irish Whiskey (or substitute with bourbon)
- 2 tablespoons lemon juice (freshly squeezed preferred)
- 1 teaspoon vanilla extract
- ½ teaspoon salt
- For the Crisp Topping:
- ⅔ cup (4 oz/115 g) dark brown sugar
- ½ cup (2 ½ oz/71 g) all-purpose flour
- 1 teaspoon cinnamon
- ¼ teaspoon salt
- 6 tablespoons (3 oz/85 g) butter, cold and diced
- ⅔ cup (2 oz/57 g) old-fashioned rolled oats
- 1 tablespoon O’Driscolls Irish Whiskey (optional, for extra flavor)
Step-by-Step Instructions
- Preheat the oven: Set your oven to 350°F (180°C) and lightly grease a 9-inch (23 cm) baking dish.
- Prepare the apple filling: In a medium bowl, toss the sliced apples with dark brown sugar, flour, cinnamon, whiskey, lemon juice, vanilla extract, and salt until evenly coated. Transfer the mixture to the prepared baking dish.
- Make the crisp topping: In the same bowl, combine dark brown sugar, flour, cinnamon, and salt. Cut in the cold butter using a pastry blender or your fingers until the mixture resembles coarse breadcrumbs. Stir in the oats and whiskey (if using).
- Assemble and bake: Sprinkle the crisp topping evenly over the apple filling. Bake for about 45 minutes, or until the topping is golden brown and the apples are tender and bubbling.
- Cool and serve: Let the crisp cool for 20 minutes before serving. Enjoy warm with a scoop of vanilla ice cream for the perfect finish!
- Storage tip: This dessert is best enjoyed the day it’s made, but leftovers can be stored loosely covered in the refrigerator for up to 2 days. Reheat in a 350°F (180°C) oven for 10 minutes before serving.
Perfect Pairings: Serving Suggestions
This Boozy Whiskey Apple Crisp is a showstopper on its own, but pairing it with the right accompaniments can take it to the next level. Serve it warm with a scoop of vanilla ice cream for a classic combo.
For a twist, try a dollop of whipped cream infused with a splash of Irish whiskey. If you’re feeling fancy, drizzle some caramel sauce over the top! It’s also delicious alongside a cup of hot coffee or spiced chai tea for a cozy fall dessert.
Storage Tips and Reheating Tricks
While this dessert is best enjoyed fresh, you can store leftovers loosely covered in the refrigerator for up to 2 days. To reheat, pop it back into a preheated 350°F (180°C) oven for about 10 minutes until warm and crispy again. If you’re short on time, a quick zap in the microwave works, though the topping may lose some of its crunch.
Whiskey-Infused Variations
Want to mix things up? Swap the Granny Smith apples for Honeycrisp or Fuji apples for a sweeter twist. Not a fan of whiskey? Substitute with bourbon or even rum for a different flavor profile. For a nutty crunch, add a handful of chopped pecans or walnuts to the crisp topping. The possibilities are endless!
Time-Saving Tips for Busy Bakers
Short on time? Opt for a pre-packaged apple slicer to speed up the peeling and coring process. You can also prepare the apple filling and topping a day in advance—just store them separately in the fridge and assemble before baking. For an even quicker assembly, use a ready-made crumble topping and just add the whiskey!
Essential Equipment Guidance
To make this recipe a breeze, arm yourself with a 9-inch baking dish and a pastry blender (or just use your hands!) to mix the topping. A sharp chef’s knife and a cutting board are key for slicing the apples evenly. Don’t forget a medium mixing bowl for tossing everything together. With the right tools, you’ll be set for success!
