    This Single Serve Apple Crisp recipe is a mini fruit crisp recipe that is baked up in a ramekin and is the perfect individual serving for one. I love that you only need one apple to make it and it's topped with the best crispy oat topping.

    ⭐Why I Love It:

    • Crispy Oat Topping - Oats are a classic ingredient in a crisp to give that signature crunch! Another favorite fruit crisp recipe is this Single Serve Microwave Mug Apple Crisp or full batch Grilled Peach Crisp! Or for a full batch Apple Crisp recipe, I love this Easy Apple Crisp!
    • Super Small Batch Dessert Recipe - I love that this single serve apple crisp recipe makes just one crisp that is perfect for one person! I have a similar recipe for a Single Serve Blueberry Crisp! Or if you're craving a pie recipe, try this Single Serve Apple Pie or Single Serve Pecan Pie recipe!
    • Only One Apple - You only need one medium-large apple to make this recipe and peeling is optional!

    🥘Ingredients

    Ingredients for an individual apple crisp in small glass prep bowls.

    For the Crisp Topping

    • Melted Unsalted Butter - This helps bind the oat topping together. You can also use salted butter and just omit the salt.
    • Brown Sugar - When measuring brown sugar, make sure you pack it into the measuring cup. I typically use light brown sugar for this recipe, but dark brown sugar works too.
    • Classic Oats - Also known as Rolled Oats or Old Fashioned Oats. These add that classic crunch to the crisp topping.
    • All Purpose Flour - You'll want to use the 'spoon and level' method when measuring flour to avoid over measuring. If you want to make this recipe gluten free, you can use a 1:1 Gluten Free Flour Blend.
    • Ground Cinnamon - I like to add a little cinnamon to both the topping and the apple filling.

    Apple Filling

    • Apple - It's up to you on what type of apple you use! Granny Smith is a popular choice for baking, but I've made this many times with a Honey Crisp as well and it's great! Peeling the apple is up to you then just a quick chop!
    • All Purpose Flour and White Sugar - A little bit of flour and sugar helps sweeten the apple filling and helps the juices thicken.
    • Ground Cinnamon - I like to add a little cinnamon to complement the apple flavor.

    See the recipe card for full information on ingredients and quantities.

    🔪Step by Step

    💭Recipe Tips

    • Leftovers and Storage - Leftover apple crisp can be stored in the fridge, covered, for up to 5 days or at room temperature for 2 days.
    • Use 'Spoon and Level' Method When Measuring Flour - When measuring flour, make sure to use the 'spoon and level' method. This is where you spoon the flour into the measuring cup and then level off the top. Instead of dipping the measuring cup directly into the flour bin which can lead to over measuring.
    • Peeling the Apple is Optional - I don't mind the texture of the skin on cooked apples, so I typically leave the skin on to keep prep easier! But you can peel the apple if you don't like the texture of the skin after cooking.

    👩‍🍳Recipe FAQs

    How do you tell when an apple crisp is done baking?

    Apple crisp is done when the crisp topping is golden brown, the juices are bubbling, and the apples are tender when pierced with a sharp knife.

    Can this recipe be made gluten free?

    Yes! Fruit crisp recipes are easy to make gluten free. Just swap out the flour for a 1:1 gluten free flour blend.

    • Author: Kathleen Hansen
    • Prep Time: 5 minutes
    • Cook Time: 35 minutes
    • Total Time: 40 minutes
    • Yield: 1-2 servings
    • Category: Dessert, Single Serve
    • Method: Oven
    • Cuisine: American

    Ingredients

    Apples

    • 1 medium-large apple, diced (skin on or off)
    • 2 teaspoons all-purpose flour
    • 2 teaspoon white granulated sugar
    • ⅛-¼ teaspoon ground cinnamon, depending on preference and apple size

    Crisp Topping

    • 1 tablespoon packed brown sugar, light or dark
    • 2 tablespoons melted unsalted butter
    • 3 tablespoons all-purpose flour
    • 2 tablespoons classic rolled oats
    • Pinch salt, omit if using salted butter

    Instructions

    1. Prep - Preheat oven to 350 degrees F. Grease a ramekin with butter (or spray with cooking spray).
    2. Prep Apples - Toss diced apples with the flour, sugar, and cinnamon. Add to greased ramekin 
    3. Crisp Topping - Mix together the crisp topping ingredients and crumble on top of the apples.
    4. Bake - Bake for about 35 minutes until the crisp topping is golden, the apples are tender when pierced with a sharp knife, and the juices are starting to bubble.  Bake time will depend on ramekin size, the size of apple, and how big your pieces. If the crisp topping is getting brown, I like to place a piece of foil on top to stop the browning.
    5. Enjoy - Allow to cool slightly (the juices will thicken as it cools) and enjoy!

    Notes

    Ramekin Size - Pictured is a 10 oz ramekin (when measured to the top rim) that is ~4.25 inches wide. The size of ramekin needed depends on how big your apple is. I've also used a smaller 7-8oz ramekin when using a smaller sized apple. It's okay if it's pretty full as the apples will cook down.
