What’s The Difference Between A Crumble And A Crisp?

Choosing between the terms “blueberry crumble” and “blueberry crisp” can seem like a culinary conundrum, but either way, you’re in for a delightful dessert experience. While both desserts feature a baked fruit base and a sugary topping, the nuances that set them apart are subtle yet impactful.

In general, a “crisp” features a crumbly, slightly crunchy topping made from a blend of butter, sugar, and often flour or oats. This gives the dessert its characteristic “crisp” texture.

On the other hand, a “crumble” is similar but may incorporate additional ingredients like chopped nuts or warm spices such as cinnamon and nutmeg, creating a slightly different texture and flavor profile.

Given that our recipe includes a deliciously crumbly topping, we’ve opted to label it as a “blueberry crumble.” So, let’s focus less on nomenclature and more on enjoying this irresistible treat!

Ingredients

If you have any ingredients leftover from this single serving blueberry crumble recipe, check out our Leftover Ingredients Recipe Finder.

  • Blueberries: While fresh blueberries are the go-to for this recipe, frozen blueberries can easily stand in. Just make sure to thaw them before incorporating into the mix. Got extra blueberries? Make a Blueberry Coffee Cake, Baked Oatmeal, or add them to a Green Smoothie.
  • Sugars: A combination of granulated sugar for the filling and a blend of granulated and brown sugar for the crumbly topping strikes the perfect balance of sweetness and complexity.
  • Flour: All-purpose flour is the ideal choice here, providing structure without altering the flavor.
  • Lemon juice: Whether you choose freshly squeezed or bottled, lemon juice is key for brightening the flavors and cutting through the sweetness. Consider using extra lemon juice in a mini Lemon Cake.
  • Butter: Ensure the butter is softened but still cool to the touch. Softened butter is essential for creating that perfect crumble texture.
  • Oats: Old-fashioned oats, also known as rolled oats, yield the best results for a traditional crumble texture. If you’ve got leftover oats, consider using them in Baked Oatmeal or in a small batch of the best Oatmeal Cookies!
  • Salt and Vanilla extract: These ingredients are flavor enhancers that elevate the entire dish.
  • Vanilla ice cream or whipped cream: These are optional but highly recommended toppings that add a creamy contrast to the fruit and crumble layers.

This is just an overview of the ingredients I used and why I used them. For the full recipe please scroll down to the recipe box at the bottom of the post.

Recipe Variations

Love the base but want to shake things up? These variations let you keep the comfort of familiarity while exploring new tastes.

  • Mixed Berry Crumble: Swap out the blueberries for an equal amount of mixed berries like raspberries, strawberries, and blackberries. This creates a tart and sweet combination that’s a berry lover’s dream.
  • Peach Blueberry Crumble: Add some sliced peaches to the blueberry mixture for a pop of color and a more complex flavor profile. Just replace half of the blueberries with an equal amount of sliced peaches.
  • Tropical Crumble: Looking for something exotic? Substitute half of the blueberries with diced mango and a sprinkle of shredded coconut. This tropical rendition will transport your taste buds to paradise.
  • Nutty Topping: Give your crumble a little crunch by adding some chopped nuts to the topping. Almonds, pecans, or walnuts would all work fabulously here. Just fold in about 1 tablespoon into the crumble mixture before baking.

With these variations, you can make this individual blueberry crumble uniquely yours. Enjoy experimenting!

How To Make A Blueberry Crumble

These step-by-step photos and instructions help you visualize how to make a small batch blueberry crumble. See the recipe box below for ingredient amounts and full recipe instructions.

  1. Preheat the oven to 375 degrees F (190 degrees C).
  1. In a small bowl, toss the blueberries with sugar, flour, lemon juice, and salt. Transfer the berries to a small baking dish.

Pro Tip: I use a 4×6-inch baking dish that has a base area of 24 square inches or a 5×5 inch baking dish with a base area of 25 square inches. See below for other dishes we recommend.

  2. Scatter the topping over the berries in the baking dish.

Expert Tips

  • Use Fresh Fruit: The fresher the blueberries, the more flavorful the result.
  • Check Doneness: The edges should be bubbling and the top golden brown.
  • Preheat Oven: Always start with a hot oven for even cooking.
  • Tailor Your Sugar: Taste your blueberries before mixing them into the recipe. If they’re tart, consider adding a bit more sugar for balance. If they’re naturally sweet, feel free to reduce the sugar to suit your taste. This personalized approach ensures you get the perfect level of sweetness every time.

Serving Suggestions

Elevate your small blueberry crumble with these options. From adding a dollop of whipped cream to creating a breakfast parfait, these serving suggestions will make your dish even more memorable.

  • With Vanilla Ice Cream: Ice cream melts perfectly into the warm crumble.
  • Whipped Cream: A lighter alternative to ice cream.
  • Yogurt Parfait: Layer crumble with Greek yogurt for a breakfast twist.

Frequently Asked Questions

How can I soften butter quickly for a crumble topping?

To perfectly soften butter for the crumble topping, leave it out on your countertop for about 30 minutes before you need it. If you’re in a rush, you can also microwave the cold butter for 10-15 seconds. Just keep an eye on it to ensure it doesn’t melt.

What size baking dish is best for a small batch blueberry crumble?

This small batch blueberry crumble is ideally made in a 4×6-inch dish or a 5×5-inch dish. Alternative options include a 6×6-inch dish (which may result in a thinner filling and less crumble, plus a quicker bake time), or a 6-inch round dish.

These baking dishes can be viewed on our Store page.

If you would like additional information on the cooking and baking dishes I use in our “recipes for one”, please visit our FAQ page.

Can I use a different kind of topping?

If you’re looking for a different texture, consider trying a cobbler-style topping that’s more biscuit-like, similar to the one we use in our Blueberry Cobbler.

Can I make blueberry crumble ahead?

This blueberry crumble stays fresh in the fridge for up to 5 days and can be frozen for up to a month. For optimal results, freeze the crumble topping separately. When you’re ready to enjoy, bake the frozen crumble until the filling is bubbly and the topping turns golden brown.

    A lot of sugar. No need for salt if you have salted butter. Coconut brown sugar works.

    1. Joanie Zisk says:

      Thank you for your comment. We recommend using a small pinch of salt in addition to the salted butter for balance, but feel free to adjust to your preference. As for the sugar, we suggest 3 to 4 tablespoons depending on the sweetness of the berriesโ€”perhaps yours were sweeter this time. I’m glad coconut brown sugar worked for you.

  2. Steph says:

    This was lovely! I halved it, and used 1 tbsp of butter in the topping instead of 2 like halving called for. I found that for me, that halving it was a perfect amount for one. I had a little vanilla ice cream with it and this dessert his the spot. Iโ€™ll be making it again!

      Wonderful! I’m so happy you enjoyed the crumble.
