Apple Crumble Pie: A Recipe with Crispy Buttery Crumbs

Apple crumble pie is one of those baked goods many remember from childhood: crispy buttery crumbs on the bottom and top, with a thick, moist layer of cinnamon apples in between. It is different from a fluffy sponge cake—there is no batter to whip, no mixer needed, and no risk of the cake falling. The whole secret is cold butter and properly prepared crumbs.

In Eastern Europe it is often called a grated pie, because the apples are usually coarsely grated, and some bakers even grate frozen dough over the top. This recipe is simpler: the crumbs are rubbed by hand in a few minutes, and the apples can be either grated or thinly sliced. The pie keeps well, slices easily, and is even tastier the next day.

This recipe is for a 10-inch (26 cm) pan and yields 12 slices. If this isn't your first time baking it, try the variation with a farmer cheese layer—we describe it at the end of the article.

Below is the full recipe card: you can recalculate the quantities for a different pan size, check off what you've already added, and print it. After the card, each step is explained in more detail.

Ingredients and how to choose them

Butter is the most important ingredient in a crumble pie. Choose real butter (at least 80% fat, European-style 82% is even better), not a spread: margarine and blends contain more water, which makes the crumbs clump together and bake up hard rather than crispy. The butter must be cold, straight from the fridge. It is easiest to coarsely grate it into the flour—then you can rub it in within a couple of minutes before the butter softens from the heat of your hands.

Flour and sugar. Regular all-purpose flour works perfectly. We use ⅔ cup (120 g) of sugar for the crumbs—just enough for the top to caramelize and become crispy. If you prefer less sweet baked goods, you can cut it to a scant ½ cup (80–90 g), but don't use less: without sugar, the crumbs remain pale and floury.

Egg binds the crumbs so the base doesn't crumble when sliced. Some recipes skip it, but then the bottom layer is very fragile and the slices are hard to remove from the pan.

Apples. The best are tart baking apples such as Granny Smith. The crumbs are sweet, so a tart filling balances them out. If you only have sweet apples, omit the sugar in the filling entirely, but definitely keep the lemon juice. 2.2 lb (1 kg) of unpeeled apples yields about 1.9 lb (850 g) of filling after peeling and coring—this makes a thick but not overly heavy layer for a 10-inch (26 cm) pan.

Cornstarch is a small but crucial addition. Grated apples release a lot of juice; a tablespoon of potato starch or cornstarch thickens it during baking, preventing the bottom crumb layer from getting soggy.

How to bake an apple crumble pie step by step

1. Crumbs. In a large bowl, mix the flour, sugar, baking powder, and a pinch of salt. Coarsely grate the cold butter directly into the flour and rub with your fingertips (not your palms—they are warmer) until the mixture resembles wet sand. Add the egg and quickly mix with a fork or your hands—uneven crumbs the size of peas and hazelnuts should form. If the mixture clumps into one ball, the butter was too warm: simply crumble it and keep it in the fridge longer.

2. Chilling. Divide the crumbs into two equal parts and chill in the fridge for 20 minutes. Cold butter turns into steam in the oven, creating tiny pockets of air—this is exactly what makes the crumbs crispy. You can also put the top portion in the freezer: it will be easier to sprinkle, and the top will remain bumpy.

3. Filling. While the crumbs are chilling, preheat the oven to 350°F (180°C). Peel the apples, core them, and coarsely grate or cut them into ⅛-inch (3–4 mm) slices. Immediately mix with lemon juice so they don't brown, then toss with sugar, cinnamon, and cornstarch. Grated apples yield a more uniform, moister layer, while slices provide distinct apple pieces.

4. Base. Line a baking pan with parchment paper—a springform pan is the most convenient here. Pour half of the crumbs into the pan and lightly press them down with your palm or the bottom of a glass. The layer should be even but not packed into a hard slab: a base pressed too firmly will bake up hard like a cookie.

5. Apples. Spread the apple mixture along with any released juices over the base and smooth it out, leaving about ½ inch (1 cm) to the edges of the pan. This gap is important: the apples won't stick to the sides of the pan, and the crumbs at the edges will join together to enclose the filling.

6. Top. Sprinkle the second half of the crumbs evenly over the apples, but do not press them down. If the crumbs are frozen, you can simply grate them with a coarse grater directly over the pie—this creates that classic grated pie top.

7. Baking. Bake on the middle rack of the oven for 45–55 minutes. The pie is done when the top is an even golden color and the apple juices are bubbling around the edges. If using a convection setting, reduce the temperature to 325–340°F (165–170°C). In a 9½-inch (24 cm) pan, the layers will be thicker, so bake 5–10 minutes longer.

8. Cooling. This is the step that usually requires the most patience. The filling of a freshly baked pie is still runny, and the crumbs are soft, so the slices will fall apart if cut immediately. Leave the pie in the pan for at least 30 minutes, or until completely cool if you want perfectly neat slices. You can dust it with powdered sugar before serving.

Common mistakes when baking a crumble pie

The crumbs clumped into a solid dough. The butter was soft, or the mixture was kneaded by hand for too long. Use only cold butter, work with your fingertips, and do not knead—the crumbs should remain uneven.

The bottom is soggy and sticky. The apples released too much juice, and there was no cornstarch. Add a tablespoon of cornstarch, and if using very juicy apples, drain a little of the juice before adding them to the pan.

The top is pale and floury. Too little sugar in the crumbs or baked for too short a time. Bake until the top is evenly browned, and you can turn on the broiler for the last 5 minutes.

The base is hard as a cookie. The crumbs were pressed too firmly. Press just enough to make the layer even.

The pie falls apart when sliced. It was sliced while too hot, or there was no egg in the crumbs. Let the pie cool and cut it with a sharp knife warmed in hot water.

Variations: with farmer cheese, nuts, and rolled oats

Apple crumble pie with farmer cheese is a richer and moister version. Blend 14 oz (400 g) of full-fat farmer cheese with 1 egg, 3 tablespoons (40 g) of sugar, and a tablespoon of cornstarch. Spread it over the crumb base, top with the apples, and sprinkle the remaining crumbs. Bake for 55–65 minutes until the cheese layer sets. If you want a pie where the cheese is the main flavor, choose a dedicated apple cottage cheese cake.

With nuts. Mix ½ to ⅔ cup (50–70 g) of chopped walnuts or almonds into the top crumbs—the top will be even crispier and more aromatic.

With rolled oats. Replace a third of the flour with rolled oats—the crumbs will be larger and more like a classic crumble topping.

On a sheet pan for a crowd. For holidays or the office, it is convenient to bake the crumble pie in a 12x16-inch (30x40 cm) rectangular baking pan. You will need double the amount of all ingredients, but the baking time remains almost the same—45–50 minutes, because the layers stay the same thickness as in a 10-inch (26 cm) pan. A baking sheet yields about 24 squares, which are easily removed with a spatula and travel well.

With berries. Mix a handful of cranberries, lingonberries, or frozen raspberries into the apple filling—the tartness pairs perfectly with the sweet crumbs.

Lighter version

A crumble pie is not a light dessert—most of its calories come from the butter and sugar in the crumbs. Here is how much the most common modifications actually change, calculated per one of the 12 slices:

The most savings come from reducing the butter and sugar: each of these changes removes about 26–28 kcal per slice, so both together lighten the pie by about a sixth (around 55 kcal). Rolled oats barely change the calories—they add fiber and crunch. More apples add a few calories per slice because the slice becomes heavier, but you get more fruit and less dough in every bite. The farmer cheese layer, on the other hand, makes the pie more filling and higher in calories, but also richer in protein.

How many calories are in an apple crumble pie

One slice of this pie (divided into 12 slices, about 4.5 oz / 130 g) has about 310 kcal—roughly one and a half times more than an easy apple cake. The difference is due to the crumbs: they contain much more butter and flour than a fluffy sponge. Below is how many calories each ingredient contributes.

How to store and freeze

Covered at room temperature, the crumble pie keeps well for 2 days, and in the fridge for up to 4–5 days. In the fridge, the crumbs soften slightly, so before eating a slice, it is worth warming it for 5–7 minutes in a 320°F (160°C) oven—the top will become crispy again.

This pie freezes beautifully. Once completely cooled, slice it, wrap the slices in plastic wrap, and keep in the freezer for up to 3 months. You can also freeze the prepared crumbs: placed in a bag, they keep for up to 3 months, and when needed, you just need apples and half an hour—simply sprinkle the crumbs straight from the freezer.

If you want a different texture, try an easy apple cake—it is quicker and fluffier, or a shortcrust apple pie with a lattice top. And for a true heirloom bake, there is the old-fashioned apple crumb cake on a yeasted dough.
