A delicious crumble topping should be perfectly golden brown and delightfully crunchy. If your crumble topping isn’t quite hitting the mark, don’t worry! There are a few common reasons why this might happen, and luckily, they’re all easily fixable.
The Secret Ingredient: Demerara Sugar
The key to a truly crunchy crumble topping lies in the type of sugar you use. While regular white sugar will work in a pinch, it won’t provide the same level of crunch as Demerara sugar. This coarse, golden sugar has a higher molasses content, which helps to caramelize and crisp up during baking, resulting in a satisfyingly crunchy texture.
Finding the Right Balance: Ingredient Proportions
Another crucial factor for achieving a crunchy crumble topping is using the correct proportions of ingredients. The classic ratio for a crumble topping is 2 parts flour : 1 part butter : 1 part sugar. However, the exact amounts can vary depending on the recipe and your personal preferences.
If your crumble topping is turning out too soft or doughy, it might be due to having too much butter or not enough flour. Conversely, if it’s too dry and crumbly, you might need to add a bit more butter or moisture.
Here are some tips for adjusting your crumble topping recipe:
- Too much butter: If your topping is too oily or greasy, try reducing the amount of butter by 1-2 tablespoons.
- Not enough flour: If your topping is too soft or doughy, try adding 1-2 tablespoons of flour.
- Too dry: If your topping is too dry and crumbly, try adding 1-2 tablespoons of cold water or milk.
Additional Tips for a Crunchy Crumble Topping
- Use cold butter: Cold butter is essential for creating a flaky and crumbly texture. Make sure your butter is straight from the fridge before incorporating it into the dry ingredients.
- Don’t overmix: Overmixing the crumble topping will result in a tough and dense texture. Gently rub the butter into the flour and sugar until it resembles coarse crumbs.
- Chill the dough: Chilling the crumble topping dough for at least 30 minutes before baking will help it to firm up and prevent it from spreading too much in the oven.
- Bake at the right temperature: The ideal baking temperature for a crumble topping is around 350°F (175°C). This will ensure that it cooks evenly and becomes golden brown without burning.
Common Mistakes to Avoid
- Using melted butter: Melted butter will create a greasy and dense crumble topping. Always use cold, cubed butter for the best results.
- Overworking the dough: As mentioned earlier, overmixing will lead to a tough and dense texture. Aim for a light and crumbly consistency.
- Using the wrong type of sugar: Regular white sugar won’t provide the same level of crunch as Demerara sugar. Opt for the coarse, golden sugar for the best results.
- Baking at the wrong temperature: Baking at too low a temperature will result in a soft and undercooked crumble topping, while baking at too high a temperature will burn it.
By following these tips and tricks, you can ensure that your crumble topping turns out perfectly crunchy every time. Remember, the key is to use the right type of sugar, maintain the correct ingredient proportions, and avoid overmixing. With a little practice, you’ll be mastering the art of the perfect crumble topping in no time!
My trick is to use melted butter and to thoroughly stir it in rather than rubbing it in. To save on washing up, I actually frequently prepare the topping in the dish that holds my scales. 6 ounces of plain flour, 3 ounces of melted butter, and 2-3 ounces of caster sugar (or I just use half as much butter and sugar as I have weighed out flour) Prepare fruit based on type. Pour melted butter into a bowl with flour, sugar, and sifted flour. Toss together until mixed. Add to prepared fruit, bake for about 40mins.

This evening, we made a crumble and the topping turned out beautifully! We used 150 g of unsalted butter that had been left out for a few hours. Add 200 g plain flour. With minimal whisking with an electric whisk, the mixture was combined, although some clumps remained. After that, mix in 200 g of demerera sugar and 100 g of oats. It came out beautifully crunchy :).
Great. Thank you. On Sunday, I’ll add crunch and soften the rub to see if that makes a difference.
After the topping is placed over the fruit, I always add extra butter specks to it.
A Buttery Crumb Topping
This streusel recipe has been on the blog before, but for those of you who have an apple pie, coffee cake, or batch of blueberry muffins that need a crumble topping, I’ve got you (and your baked goods) covered! Today I’m sharing a really easy and quick recipe with you!
My recipe yields a crumbly, crisp, buttery streusel that tastes great on almost anything, and it’s easier than most—no pastry cutter required!—and it only takes five minutes to prepare. I also include lots of notes so you can add your preferred nuts or spices to the crumb topping.
Now that we’ve got that out of the way, let me tell you about one of my coffee cake muffins, which is the one with streusel on top!
For my streusel recipe, all you need are basic pantry staples:
- Flour. Since I’ve only tried this recipe using all-purpose flour, that’s what I suggest doing.
- Brown sugar. I use a higher proportion of brown sugar to granulated sugar for two reasons: 1) it makes the streusel clump together better, and 2) I like the slightly stronger, richer flavor. You can use dark brown sugar to make the streusel even more flavorful.
- Granulated sugar. Regular granulated sugar counteracts the streusel and prevents it from getting overly rich and sugary.
- Salt. This recipe’s tiny amount of salt counteracts the sweetness and prevents the topping from being too sweet.
- Butter. This creates the crumbly, clumpy crumble topping and binds the streusel together. I use melted butter instead of cold butter that needs to be cut in with a pastry cutter, unlike many streusel topping recipes. I use unsalted butter in my recipe to best control the flavor (see more in my post on salted vs. unsalted butter), but if you only have salted butter on hand, simply omit the salt that is called for. This method is not only easier and faster, but it also improves the flavor of the streusel!
You can choose to add spices or other flavorings if you want to elevate your crumb topping. For extra flavor depth, I frequently add a dash of nutmeg or a pinch of cinnamon. Additional choices include the spice for pumpkin pie, cardamom, cloves, lemon zest, or even a small amount of vanilla extract. Add any dry spices to the flour/sugar mixture; you can whisk in any liquid spices with the butter.
Another option that some people like to add to their crumb topping is chopped nuts, such as pecans or walnuts; I go into more detail about this in the recipe card.

FAQ
How do you keep crumble topping crunchy?
Why does my crumble topping go soggy?
Why is my streusel topping not crumbly?
Why is my crumble topping not crunchy?
The first reason a crumble topping isn’t crunchy is that it’s too dry, with more flour than butter. You’ll notice immediately that the topping is powdery and floury, with none of the caramelized nuggets of pastry you want. You don’t add enough butter.
What if my topping is too dry & crumbly?
But if you feel your topping is still too dry and crumbly, (even for a crumble) add a bit more melted butter, a tablespoon at a time. If you think it’s too wet, add a little more flour to soak up the extra butter.
Why is my crumb topping soggy?
The opposite of a powdery topping is a soggy, greasy crumble, where there is too much butter and not enough flour. You add too much butter. Add a little more flour, which will soak up the extra butter. This can happen if you use melted butter rather than rubbing in cold butter. Your crumb topping is too thick – it should be less than an inch deep.
Why is my crumb topping too thick?
Add a little more flour, which will soak up the extra butter. This can happen if you use melted butter rather than rubbing in cold butter. Your crumb topping is too thick – it should be less than an inch deep. A hefty layer of crumble topping will become dense and fatty, unable to crisp up in the oven.
