This apple sour cream cake is SO moist and delicious. Topped with a gooey cinnamon crumble, this is the perfect coffee cake to enjoy on a chilly fall day.
This coffee cake is giving me all of the cozy fall vibes! It's packed with ton of cinnamon apple flavor, and pairs perfectly with a warm cup of coffee in the morning.
While I don't discriminate when it comes to fall flavors, I think apple is pretty far up there on my list of favorites. So you just know this cake is packed with lots of fresh apple chunks!
And then of course there's the sour cream. Just like with my chocolate bundt cake, this ingredient really adds so much richness and moisture. It's irresistible!
Why You'll Love This Recipe

Ingredient Notes and Substitutions
- Gluten free flour: My favorite gluten free flour blend is Bob's Red Mill 1 to 1. If you're using a different blend, make sure it contains xanthan gum. And because this is a cup for cup flour, you should be able to substitute AP flour if you're not looking to make this cake gluten free.
- Baking powder and baking soda: Make sure your leavening agents are fresh! Otherwise the cake won't rise. Here's an easy way to test it out.
- Sour cream: This really is one of the stars of this recipe and adds some delicious richness, so make sure you're using full-fat sour cream. I wouldn't recommend substituting this ingredient with anything else. It simply won't be the same.
- Apples: I used 2 small Honeycrisp apples for this recipe, but you should be able to use just about any kind you want!
- Brown sugar: I recommend light brown sugar for the crumble topping, but dark brown will work just fine too.
STEP ONE: Start by combining your dry ingredients in a medium bowl. Whisk it all up, then set aside.
STEP TWO: Use your mixer to cream the butter with the sugar until it's smooth.
STEP THREE: Add in the sour cream and vanilla, and continue mixing until it's all incorporated.
STEP FOUR: Add the dry ingredients and mix on low speed.
STEP FIVE: Fold in the diced apples.
STEP SIX: Make the cinnamon topping by combining the three ingredients in a small bowl.
STEP SEVEN: Transfer the cake batter into a lined pan, then sprinkle the topping on top. Bake for 35-40 minutes.
- My top tip when it comes to baking, and especially gluten free baking, is to use a scale to weigh your flour. This is the only way to ensure accuracy, and too much (or too little) flour can really impact your cake.
- I like to use a fork to combine the brown sugar, cinnamon, and butter for the topping. You can use your hands, too. You just want to make sure the butter is really getting incorporated.
- The suggested bake time is 35-40 minutes, but because all ovens are different, I recommend checking in around the 35 minute mark. You'll know the cake is done when a toothpick inserted into the center comes out clean.
