Avoid These Common Mistakes and Make Perfect Fruit Crumbles Every Time (2024)

A fruit crisp or crumble is the ace up any novice baker's sleeve. It's free-form (no fussy lattice-top crusts to master) and it's forgiving (no strict ratios of ingredients that must be followed.) But that doesn't mean it's fool-proof. These are the most common mistakes people make when getting their crumble on.

1. Keep the Fruit in Big Pieces

The fruit will break apart a little as it bakes, but for harder fruits like pears and apples, says senior food editor Chris Morocco, you have to do a little knife work before assembling the crumble. Half an apple won't break down into bite-sized pieces even after a good long spin in the oven. Remove any pits, cores, and stems, then chop all fruit into small pieces. Shape doesn't matter and they need not be precise, but all pieces should be relatively similar in size.

2. Leaving Out a Thickening Agent

The ingredient list for a crumble or crisp is relatively short, but don't be tempted to leave out the cornstarch. As fruit cooks, it releases its juices, becoming saucy and soupy. This is partially what makes a crisp so delicious—but also what can turn it from a casserole-style dessert into fruit soup. (Some fruits, like red berries, contain very low amounts of pectin, meaning they won't "set up" without help). Don't have cornstarch on hand and definitely don't want to make a trip to the store? You can play around with substitutions—flour, arrowroot, potato starch, and tapioca can all be used to the same effect. Some recipes contain a mix of thickeners, which will work together just fine.

3. Not Getting Creative with the Topping

A proper crisp topping combines oats, flour, butter, and brown sugar—it's the perfect balance of rich, sweet, and hearty. But why stop there? A granola that contained just oats and butter would be boring, says Morocco. The same holds for your crumb topping. Get creative with chopped nuts, seeds, and even coconut flakes. Now we're talkin'!

4. Adding Too Much Topping

Whoa now, don't get too crazy with that crisp topping. Morocco reminds us to keep a pie's filling-to-crust ratio in mind: There shouldn't be two inches of dough covering up the fruit. Resist the urge to add too much crumb topping, or your crisp will become dense and too fatty. Remember: The fruit's the point. If you want buttery baked oats, make some granola.

5. Forgetting the Acid

Whether it's lemon juice, a splash of wine, or a good-quality vinegar, your crumble filling needs a little acidity to keep it from tasting clunky and overly sweet. Vinegar won't make your crumble taste like salad dressing, but it will perform the task of balancing out the sugar. Mix it right in with the chopped fruit, sweetener, and thickener before topping and baking. Even a little lemon zest can brighten things, says Morocco.

Why is my crumble not crumbly? ›

Often this happens if the crumb topping is over-mixed or if the butter was much too hot. Over-mixing will leave you with a pasty, batter-like mixture rather than the crumbly topping you are aiming for. Using very hot butter can cause the sugars to melt, leaving you with a greasy and not crumbly mixture.

How do you keep apples from getting mushy in crumble? ›

I usually give them a short blast in the microwave; not long enough to send them to mush, but just enough to keep their shape and texture and the oven will do the rest. I usually slice the apples quite thinly then put the crumble mixture on top and put the dish on a baking sheet.

Why put baking powder in crumble topping? ›

A crisp contains oats in the topping, while a crumble does not. Baking powder can also be added to a crumble topping (like it is here) to ensure it's extra light and tender.

What does cornstarch do in a crumble? ›

Then, make sure to bake the crumble long enough so that the fruit filling comes to a profuse simmer at the edges of the pan. This shows that the cornstarch has been activated enough to thicken the juices, turning them supple and silky.

Flatten down with your hand to prevent too much crumble falling through. Put 175g plain flour and 110g golden caster sugar in a bowl with a good pinch of salt. Slice in 110g cold butter and rub it in with your fingertips until the mixture looks like moist breadcrumbs.

Should crumble be hot or cold? ›

Apple Crumble also makes a great breakfast. Either you can microwave it, which is our usual method, or you can cover with foil and reheat at 350°f / 180°c in the oven until warmed through. Usually we tend to just warm up individual servings as needed though in the microwave. Apple crumble is also amazing cold!

Crumble requires more baking time than you think; the top should be brown and the filling should be bubbling. In order to thicken properly, the cornstarch in the filling must boil, which is why bubbling is a key indicator for doneness.

What is the difference between streusel and crumble topping? ›

Streusel is similar to crumb topping and the terms are often used interchangeably. Traditionally, the two have different ratios of the same ingredients, with streusel containing more flour, and crumb topping more sugar, so they offer a different texture and flavor on top of baked goods.

How to get crumble crunchy? ›

Double-bake your fruit crumble topping

What's the difference between apple crumble and apple crisp? ›
