Why You'll Love This Recipe
This is truly one of the best apple coffee cakes! While it's particularly awesome to enjoy during peak apple season in the fall, this is a perfect year-round recipe. If you prefer something strictly fall-based, try my Pumpkin Sour Cream Coffee Cake!
Flavor - the fresh, tart apples tossed with warm spices pair so nicely with the vanilla cake and the brown sugar streusel. It's buttery, sweet, tart, and is such a delicious apple streusel coffee cake recipe.
Texture - the cake has such a wonderful, delicate texture. Pair that with the slight bite from the apple pieces and the crunchy yet soft, crumbly texture of the coarse crumbs and it is really the perfect pairing.
Make ahead - coffee cake recipes are the perfect bake ahead options to serve for a weekend of guests or just for a quick weekday breakfast. The apple coffee cake stores at room temperature for days, and also remains moist and delicious.
- Dry ingredients. All-purpose flour, baking powder, salt.
- Dairy. Unsalted butter (both room temperature and melted butter), eggs, sour cream, and milk.
- Light brown sugar. This is the only type of sugar used in the recipe.
- Rolled oats. For the streusel topping. This can be omitted if you don't want to include them.
- Tart apples. I used Pink Lady Apples in this recipe, but other tart baking apples like Braeburn, Granny Smith, or Honey Crisp apples are also great apple varieties to use.
- Cornstarch. One tablespoon is used to thicken the apple pie filling.
- Lemon juice. For the apple pie filling.
- Spices. Ground cinnamon, cloves, and nutmeg are used in this recipe.

Substitutions & Variations
- Use greek yogurt in place of sour cream. Just be sure to use a high-fat version.
- Use 120ml (½ cup) of buttermilk in place of both the sour cream and milk.
- Omit the rolled oats from the crumb topping if you aren't into it.
- Add up to ⅓ cup chopped pecans, walnuts, or almonds for extra crunch. Add them to the top during the last 10 minutes of baking.
- Add ½ teaspoon of ground cinnamon to the topping to make a cinnamon streusel.
- Use slightly firm pears in place of apples for another seasonal version.
- Make the sour cream coffee cake in a springform pan (9") and bake for roughly 10 minutes less.
How to Make This Recipe
One: Cook the fresh apples, sugar, lemon juice, and spices in a saucepan over medium heat. Then add the cornstarch, water, and vanilla.
Two: In a medium bowl, use a fork to mix the streusel ingredients until medium and small chunks form.
Three: In the bowl of a stand mixer (or using a hand mixer), cream together the butter and sugar, then the eggs and vanilla. Add half of the flour mixture and mix to combine.
Four: Mix together the sour cream and milk and add half to combine into the batter. Then add the remaining flour, then the last of the milk mixture.
Five: Pour the cake batter into the prepared square pan, then spread the apple mixture over top.
Six: Sprinkle the crumble mixture evenly over the apples, then bake until risen and the cake is set. Cool completely, then slice and serve.
Hot tip! Use a large, sharp knife to cut the apple streusel coffee cake, cleaning the blade in between each cut for the cleanest slices.
- Try not to cut the apple slices too large. You want them to be in easily edible pieces.
- Preparing the pan with parchment paper allows you to remove the cake from the pan to cut it more easily. It's always best to remove the cake to cut it so you don't scratch the bottom of your pan.
- Don't over-mix the cake batter! Too much mixing can result in a tough, dry cake rather than a moist delicate crumb.
- Cool the cake on a wire rack so air can circulate under the bottom of the pan and cool it more quickly.
Using tart, firm apples that specifically hold up to baking and heat are best. These are apples such as Granny Smith, Braeburn, Pink Lady, or Honey Crisp, which hold their flavor and texture.
Traditionally, streusel, crumble or crumb topping is made from a mixture of flour, sugar, and butter. I typically like to add old-fashioned oats for a bit of extra texture. A variety of nuts can also be incorporated.
Store the apple crumble coffee cake lightly covered at room temperature for up to five days or in the fridge for a week. I like to allow just a bit of air into the container so the streusel topping doesn't turn mushy. The apples help to keep the cake moist, so it doesn't dry out too quickly using this method.
To freeze the coffee cake, wrap the cake or individual slices tightly in plastic wrap, then foil, and place it into an airtight container or zip-top bag. Freeze for three months. Unwrap the cake completely, then thaw at room temperature for about one to two hours.

This was such a treat for Christmas morning breakfast. The gooey apples and spongey cake were perfection. I love that it’s decadent, but not overly sweet!
I feel the same about this cake!! Glad to hear this.
