Apple Crumb Cake with Cinnamon Apple Drizzle tastes like a cozy fall afternoon baked into a pan, with tender spiced apples, a soft buttery cake, and a crunchy brown sugar crumb on top. It works perfectly for brunch, dessert, or a coffee break, and you can have it on the table in about 1 hour 15 minutes. I tested this version on my neighbors, and they “forgot” to return the pan, which says everything.

Why Choose This Apple Crumb Cake with Cinnamon Apple Drizzle

This apple crumb cake bakes up with three distinct layers: a soft sour cream cake, juicy cinnamon apples, and a thick, crunchy crumb that stays crisp. The warm cinnamon apple drizzle sinks into every nook and cranny and turns each slice into something between coffee cake and apple pie.

You mix everything in basic bowls, no mixer required, and the ingredients stay budget friendly. The recipe also works beautifully with slightly sad, wrinkly apples, so you rescue produce and get dessert at the same time.

Ingredients You’ll Need

For the cake base

1 ½ cups all-purpose flour (spooned and leveled; I like King Arthur or Gold Medal)
1 teaspoon baking powder
½ teaspoon baking soda
½ teaspoon fine sea salt
½ cup unsalted butter, melted and slightly cooled
¾ cup granulated sugar
2 large eggs, room temperature
1 teaspoon pure vanilla extract (use real vanilla, not imitation, for best flavor)
¾ cup sour cream or plain Greek yogurt (full fat tastes best, but 2% works)

For the cinnamon apple layer

3 medium apples, peeled, cored, and diced small
- Use firm baking apples like Honeycrisp, Granny Smith, Pink Lady, or a mix
2 tablespoons granulated sugar
1 tablespoon light brown sugar, packed
1 ½ teaspoons ground cinnamon
1 teaspoon lemon juice (bottled works fine in a pinch)
1 tablespoon all-purpose flour (helps thicken the juices)

For the crumb topping

1 cup all-purpose flour
½ cup light brown sugar, packed
¼ cup granulated sugar
1 teaspoon ground cinnamon
¼ teaspoon fine sea salt
½ cup unsalted butter, melted and slightly cooled

For the Cinnamon Apple Drizzle

1 cup powdered sugar, sifted
2–3 tablespoons apple cider or apple juice (milk works if you do not have cider)
½ teaspoon ground cinnamon
¼ teaspoon vanilla extract
Pinch of salt

Pantry shortcuts and substitutions

Use pre-cut apple slices from the produce section if you feel short on time; just dice them smaller.
Swap half the all-purpose flour in the crumb with oat flour for a slightly nutty flavor.
Use coconut sugar in the crumb topping if you prefer a deeper caramel note.
Use store-brand butter and sugar; they work just as well as premium brands in this recipe.

Equipment list

8-inch or 9-inch square baking pan (metal or glass; line with parchment for easy lifting)
Mixing bowls: 1 large, 2 medium, 1 small
Whisk and rubber spatula
Measuring cups and spoons
Knife and cutting board for apples
Cooling rack
Small spoon or squeeze bottle for the drizzle

Tips & Tricks

Line the pan with parchment and leave an overhang so you lift the whole cake out cleanly.
Dice the apples small and even so they soften fully and spread into a uniform layer.
Use room temperature eggs and sour cream so the batter mixes smoothly and bakes evenly.
Stir the crumb topping just until large clumps form; squeeze some in your hands to create big crunchy chunks.
Do not overmix the cake batter; stop as soon as the flour disappears to keep the crumb tender.
Taste an apple cube before baking and adjust cinnamon or sugar if your apples taste very tart.
Let the cake cool at least 30 minutes before you slice so it sets and does not crumble apart.
Add the cinnamon apple drizzle when the cake feels just slightly warm so it sinks in a bit but does not melt completely.
Use a light-colored metal pan if you have one; dark pans brown the edges faster, so check a few minutes early.
Test doneness with a toothpick in the cake portion, not the crumb; a few moist crumbs count as done, but wet batter means more time.

How to Make Apple Crumb Cake with Cinnamon Apple Drizzle

Step 1: Prep the pan and oven

Heat your oven to 350°F (175°C).
Grease an 8-inch or 9-inch square pan with butter or nonstick spray.
Line the bottom and two sides with parchment, leaving a little overhang as handles.

Step 2: Mix the apple layer

Add the diced apples to a medium bowl.
Sprinkle in granulated sugar, brown sugar, cinnamon, lemon juice, and flour.
Toss until every apple piece looks coated and no dry flour remains, then set the bowl aside.

Step 3: Make the crumb topping

In another medium bowl, whisk flour, brown sugar, granulated sugar, cinnamon, and salt.
Pour in the melted butter.
Stir with a fork until the mixture forms clumps; squeeze some together with your fingers to build larger crumbs, then chill the bowl in the fridge while you mix the cake batter.

Step 4: Mix the cake batter

In a large bowl, whisk melted butter and granulated sugar until the mixture looks thick and glossy.
Add eggs one at a time, whisking well after each, then stir in vanilla.
In a separate small bowl, whisk flour, baking powder, baking soda, and salt.
Add half the dry ingredients to the wet mixture and stir just until combined.
Add the sour cream and mix until smooth.
Add the remaining dry ingredients and fold gently until no dry streaks remain.

Step 5: Assemble the layers

Spread the cake batter evenly into the prepared pan; the layer will look fairly thick.
Scatter the cinnamon apple mixture evenly over the batter, including any juices from the bowl.
Take the chilled crumb topping from the fridge and sprinkle it over the apples, covering the surface completely with big and small clumps.

Step 6: Bake the apple crumb cake

Place the pan on the center rack of the oven.
Bake 40–50 minutes, depending on your pan size and oven.
Start checking at 38–40 minutes; insert a toothpick into the cake portion near the center.
Pull the cake out when the toothpick shows a few moist crumbs but no wet batter and the crumb topping looks golden brown.

Step 7: Cool the cake

Set the pan on a cooling rack.
Let the cake cool in the pan at least 30–40 minutes.
Lift it out by the parchment if you lined the pan, then cool a bit longer if you want very clean slices.

Step 8: Make the Cinnamon Apple Drizzle

In a small bowl, whisk powdered sugar, cinnamon, salt, vanilla, and 2 tablespoons of apple cider or juice.
Check the consistency; you want a thick but pourable drizzle that slowly runs off the spoon.
Add the remaining cider or a tiny splash more if it looks too thick, or add a spoonful of powdered sugar if it looks too thin.
Taste and adjust cinnamon or vanilla to your liking.

Step 9: Drizzle and serve

When the cake feels just slightly warm, spoon or zigzag the cinnamon apple drizzle over the top.
Let the drizzle set for about 10 minutes.
Slice into squares and serve with coffee, tea, or a cold glass of milk.
Watch the corner pieces disappear first, because that crumb-to-cake ratio wins every time.

What to Serve with it?

Serve this apple crumb cake warm with a scoop of vanilla ice cream or a dollop of lightly sweetened whipped cream. A mug of hot coffee, chai, or cinnamon-spiced herbal tea pairs perfectly with the cinnamon apple drizzle and crumb topping. Add fresh fruit on the side, like orange slices or berries, if you want a brunch spread that feels a bit lighter. This cake also works nicely on a breakfast table next to scrambled eggs, yogurt, and granola so everyone builds their own sweet-and-savory plate.

Storage Options

Store leftover apple crumb cake tightly covered at room temperature for up to 2 days if your kitchen stays cool.
Keep it in the fridge for up to 5 days; reheat slices in the microwave for 15–20 seconds or in a 300°F oven for about 8–10 minutes.
Freeze individual slices by wrapping them in plastic, then placing them in a freezer bag; they keep well for up to 2 months.
Thaw frozen slices in the fridge overnight or at room temperature for about an hour, then warm them briefly in the oven or microwave before serving.
