Cinnamon Apple Crumb Cake

There’s something about the combination of fresh apples, warm cinnamon, buttery crumb topping, and maple icing that instantly feels like fall.

This Cinnamon Apple Crumb Cake is soft, moist, generously packed with diced apples, and finished with a thick brown-butter cinnamon crumb topping. A simple drizzle of maple icing takes it over the top.

It’s the kind of homemade apple cake that works beautifully for a cozy weekend breakfast, afternoon coffee, Thanksgiving dessert, or an easy fall treat when you want the kitchen to smell amazing.

Why You’ll Love This Apple Crumb Cake

This isn’t a thin, delicate coffee cake. It has a generous layer of buttery crumb topping that becomes golden and slightly crisp while the cake underneath stays soft and moist.

Here’s what makes it special:

• Fresh diced apples add moisture and natural sweetness.
• Brown butter gives the crumb topping a deeper, nutty flavor.
• Cinnamon brings classic warm fall flavor.
• Sour cream helps keep the cake tender and moist.
• Maple icing adds just the right amount of sweetness.
• It’s made in a simple 8-inch square baking pan.
• It’s delicious slightly warm or completely cooled.

What Kind of Apples Are Best?

You can use several varieties of apples for this cake. Apples that are naturally sweet-tart and hold their shape during baking work particularly well.

Honeycrisp, Pink Lady, Granny Smith, or Braeburn are all good choices.

For a sweeter cake, use a sweeter apple. For a little more contrast against the brown sugar and maple icing, a tart apple such as Granny Smith works beautifully.

How to Make Cinnamon Apple Crumb Cake

1. Prepare the Apples

Peel and core two medium apples, then cut them into small, even pieces.

Keeping the pieces relatively small helps them distribute throughout the cake instead of sinking into one area.

2. Brown the Butter

Melt ½ cup of butter in a small saucepan over medium heat.

Continue cooking until the butter becomes golden brown and develops a nutty aroma. Watch it carefully because browned butter can quickly go from perfectly golden to burnt. Set it aside to cool slightly.

3. Make the Crumb Topping

Combine the flour, brown sugar, cinnamon, and salt in a bowl.

Pour in the browned butter and mix until chunky crumbs form.

You want a mixture with different-sized crumbs rather than a smooth paste. Those larger pieces create the delicious crunchy topping once baked.

4. Make the Cake Batter

Whisk together the flour, baking powder, baking soda, salt, and cinnamon.

In a separate bowl, beat the softened butter and brown sugar until light and fluffy. Add the eggs one at a time, followed by the vanilla extract.

Mix in the sour cream and milk. Gradually add the dry ingredients and mix just until combined. Avoid overmixing the batter.

5. Add the Apples

Gently fold the diced apples into the cake batter. The apples should be evenly distributed throughout the mixture without breaking them apart.

6. Fill the Pan

Line an 8-inch square baking pan with parchment paper. Transfer the apple cake batter into the pan and spread it evenly.

7. Add the Crumb Topping

Generously scatter the prepared brown-butter crumb mixture over the entire surface of the cake batter.

Don’t press the crumbs down too firmly. Keeping them loose helps create that chunky, bakery-style crumb topping.

8. Bake

Bake at 350°F (175°C) for 40–45 minutes. The top should be golden brown, and a toothpick inserted into the center should come out with a few moist crumbs but no wet batter. Let the cake cool before adding the icing.

9. Make the Maple Icing

Whisk together powdered sugar, maple syrup, milk, and vanilla extract.

Add the milk gradually until you reach a thick but pourable consistency.

10. Drizzle and Serve

Drizzle the maple icing over the cooled apple crumb cake. Slice into squares and serve.

The contrast between the soft apple cake, crunchy cinnamon crumb topping, and sweet maple icing makes every bite incredibly satisfying.

Tips for Making the Best Apple Crumb Cake

Don’t overmix the batter.
Once the dry ingredients are incorporated, stop mixing. Overmixing can make the cake dense.

Cut the apples evenly.
Small, uniform pieces distribute better throughout the batter and cook evenly.

Watch the brown butter carefully.
The butter can change from golden brown to burnt very quickly. Remove it from the heat as soon as it reaches a nutty golden color.

Let the cake cool before icing.
If the cake is too hot, the maple icing will melt and disappear into the crumb topping.

Keep the crumb topping chunky.
Large and small crumbs create a much better texture than a finely mixed topping.

What to Serve with Apple Crumb Cake

This cake is delicious on its own, but it pairs especially well with:

• A hot cup of coffee
• Apple cider
• Black tea
• Chai tea
• A scoop of vanilla ice cream
• A warm latte

For a cozy fall dessert, serve a slightly warm slice with vanilla ice cream and let the crumb topping soften just a little.
