Apple Crumb Cake: Grandma's Old-Fashioned Yeasted Recipe

Many remember this old-fashioned apple crumb cake not from a cookbook, but from their grandmother's kitchen: a large sheet pan, yeasted dough rising under a towel in a warm spot, tightly packed apples from the backyard tree, and a crispy buttery streusel on top. It isn't baked for one dessert but for the whole family and their guests—one sheet pan yields twenty hearty slices.

It differs from a quick sponge cake in the dough itself. The yeasted dough isn't overly sweet or crumbly—it's soft, slightly elastic, smells like fresh bread, and perfectly absorbs the apple juices without getting soggy. Baking powder became common in everyday kitchens much later, so for a long time, cakes were leavened with yeast. It takes a bit more work, but the dough does most of the rising on its own while you prep the apples.

This recipe is a classic yeasted sheet-pan apple crumb cake. At the end of the article, you'll also find a second old-fashioned variation—with a shortcrust pastry and a sour cream custard—which many also call grandma's apple cake.

The full recipe is in the card below: you can double or halve the amounts, check off what you've added, and print it out. After the card, each step is explained in more detail.

Ingredients and How to Choose Them

Yeast. Fresh yeast should be moist, light beige, and crumble easily—darkened or hardened yeast often no longer works. 25 g (about 1 oz) of fresh yeast equals one ¼-oz packet (2 ¼ tsp or 7 g) of active dry or instant yeast. Instant (rapid-rise) yeast can be mixed straight into the flour and needs no starter; active dry yeast should be dissolved in the warm milk first.

Milk. It should be warm, not hot—about 98°F (37°C), a temperature where your finger barely feels it. Milk that is too hot (above 115–120°F / 45–50°C) will kill the yeast, while cold milk will significantly slow down the rise.

Flour. Regular all-purpose flour works perfectly. You might need slightly more or less depending on the size of your eggs and the humidity of the flour: it's best to hold back a little flour and add it gradually until the dough stops being sticky.

Apples. Tart baking apples such as Granny Smith are best for this old-fashioned cake. Their tartness balances the sweet streusel, and since the apple layer is thick, overly sweet apples would make the cake too sugary. If your apples are very juicy, mix them with sugar right before arranging them—otherwise, they will release too much juice.

Butter for the streusel must be cold, straight from the fridge. Only then, when rubbed with flour and sugar, will it form distinct clumps that become crispy when baked. Soft butter will turn into a sticky paste instead of a crumb topping.

How to Bake an Old-Fashioned Apple Crumb Cake

First, prepare the starter. Mash the fresh yeast with a teaspoon of sugar, pour in half of the warm milk, add a couple of tablespoons of flour, and leave in a warm place. After 10–15 minutes, a foamy cap should appear on the surface—this is a sign that the yeast is alive. If nothing happens after 20 minutes, it's better to discard it and start over with fresh yeast.

In a large bowl, combine the flour and salt, then pour in the yeast starter, the remaining milk, sugar, and eggs. Knead for about 8–10 minutes by hand or 5–6 minutes with a stand mixer fitted with a dough hook. Mix in the melted butter at the very end, once the dough has formed: fat added too early coats the flour and prevents gluten development, resulting in a less elastic dough. A well-kneaded dough is smooth, shiny, and no longer sticks to the bowl or your hands.

Cover the bowl with a towel or plastic wrap and leave it in a warm, draft-free place—near a radiator, in an off oven with the light on, or just on the kitchen counter. The dough should double in size; this usually takes about an hour, or longer in a cooler room. Don't watch the clock: what matters is how the dough looks.

While the dough rises, prepare the apples and streusel. Peel the apples, core them, and cut them into ¼-inch (5 mm) thick slices. For the streusel, rub the flour, sugar, and cubed cold butter together with your fingertips until you get crumbs of various sizes. Keep them in the fridge until ready to use.

Briefly knead the risen dough to knock out large air bubbles, and roll it out into a rectangle about the size of your baking sheet, roughly ½-inch (1 cm) thick. Transfer it to a buttered or parchment-lined 12x16-inch (30x40 cm) baking sheet, smooth it out with your fingers, and slightly raise the edges—they will hold in the apple juices.

Toss the apples with sugar and cinnamon and arrange them tightly over the dough. Leave any juices that have pooled at the bottom of the bowl—they will only make the dough soggy. Evenly sprinkle the streusel over the top and let the cake rise for another 20 minutes. This second rise is crucial: without it, the dough under the apples will be dense and damp.

Meanwhile, preheat the oven to 375°F (190°C) or 350°F (175°C) for convection. Bake on the middle rack for 25–30 minutes, until the streusel is golden and the edges of the dough are reddish-brown. If you lift a corner and see the bottom is still pale, bake for another 5 minutes on the bottom rack.

Let the baked cake rest in the pan for at least 20 minutes. The hot apple layer is still loose, but it sets as it cools, ensuring neat slices.

Common Mistakes

The dough isn't rising. Old yeast or milk that is too hot is usually to blame. Check if the starter foamed, and only heat the milk to body temperature. In a cold kitchen, the dough simply needs more time—sometimes up to an hour and a half or two hours.

The dough is hard and dry. Too much flour was added. Yeasted dough is always sticky at first, but it becomes smooth as you knead it. If you keep adding flour to stop it from sticking, you'll "kill" its texture. It's better to grease your hands with a little oil.

The dough under the apples is soggy and underbaked. Apple juices were poured over the dough, the second rise was skipped, or the temperature was too low. Arrange the apples without their juices, let the cake rise, and bake in a hot oven.

The streusel melted into a crust. The butter was too soft, or the streusel sat in a warm place for too long. Always rub it together using cold butter and keep it in the fridge until you're ready to sprinkle it.

The edges burned, but the center is pale. The oven bakes unevenly. Rotate the pan 180 degrees halfway through baking.

Another Old-Fashioned Variation: With Sour Cream Custard

A second cake that many families call grandma's apple cake is baked without yeast. The base is a shortcrust pastry, and the apples are covered with a sour cream and egg mixture that sets like a delicate custard as it bakes. You'll need a 9½- to 10-inch (24–26 cm) pan.

• For the dough: 1 ⅔ cups (200 g) all-purpose flour, 7 tbsp (100 g) cold butter, 2 tbsp sour cream, 2 tbsp sugar, ½ tsp baking powder.
• For the filling: 1.5 lb (700 g) apples, 1 tsp cinnamon.
• For the custard: 1 ¼ cups (300 g) full-fat sour cream, 1 egg, ½ cup (100 g) sugar, 2 tbsp flour, 1 tsp vanilla extract.

Rub the butter into the flour, sugar, and baking powder, knead in the sour cream, and chill for half an hour. Press the dough into the bottom and sides of the pan, arrange the apple slices tossed with cinnamon, and pour the whisked sour cream mixture over the top. Bake at 350°F (180°C) for about 50 minutes, until the custard sets and the edges are golden. Let the cake cool completely before slicing, preferably for a few hours in the fridge. The custard will firm up, and the slices will be neat.

Substitutions

• Fresh yeast – with dry yeast: use one ¼-oz packet (2 ¼ tsp or 7 g) instead of 25 g (1 oz) of fresh yeast. Instant yeast goes straight into the flour; active dry yeast is dissolved in the warm milk first.
• Butter for the dough – with ¼ cup (60 ml) of oil. The dough will be slightly less fragrant but just as soft.
• Milk – with kefir or buttermilk. The dough will have a slight tang, typical of many rustic bakes.
• Streusel – with an egg wash and cinnamon sugar, if you prefer a lighter cake.
• Apples – partially with plums or pears; they pair beautifully in the same cake during the fall.

Lighter Version

This old-fashioned cake is filling, but a single slice isn't as calorie-dense as it might seem: a lot of the bulk comes from the apples. Here is how the calories in one slice (when cutting the pan into 20 slices) change with common modifications.

The most calories are saved by skipping the streusel—it accounts for about a quarter of the energy in a single slice. Reducing the sugar in the dough and filling doesn't do much, as most of the sugar is in the streusel. Whole wheat flour barely reduces the calories but adds fiber and a richer, nutty flavor that pairs very well with yeasted dough.

How Many Calories Are in an Apple Crumb Cake?

One slice (about 4 oz or 115 g, when cutting the pan into 20 slices) has roughly 240 calories. The largest portion of energy comes from the flour and butter. The apple layer, although the thickest, adds very few calories—2.2 lb (1 kg) of peeled apples make up almost half the cake's weight but contribute only about a tenth of its energy.

Storage and Freezing

A yeasted cake is best on the first day. Covered with a towel, it stays fresh at room temperature for 1–2 days; after that, store it in an airtight container in the fridge for up to 4 days. To make the yeasted dough soft again, warm the slice in a 320°F (160°C) oven for 5–7 minutes before eating. The streusel will become crispy again.

Yeasted cakes freeze well: wrap completely cooled squares individually and keep them in the freezer for up to 3 months. Thaw at room temperature and briefly warm in the oven.

If you don't have time for yeasted dough today, choose an easy apple cake that can be prepped in just a few minutes. If you want similar crispy streusel on a shortcrust base, try an apple crumble pie, and if you prefer richer bakes, an apple cottage cheese cake is perfect.
