How to Make Apple Crumble Cake
1. Prepare the pan and apples
Heat the oven to 350°F. Butter an 8-inch square pan so the cake can be removed more easily after baking. Peel the apples, cut them into small pieces, and dice them evenly. Smaller pieces soften more easily and distribute through the cake instead of creating large wet pockets.
2. Make the cake batter
In a mixing bowl, whisk together the 1½ cups flour, ¾ cup sugar, baking powder, and salt. In a separate bowl or measuring cup, combine the ½ cup melted butter, eggs, milk, and vanilla. Pour the wet mixture into the dry mixture and stir until the batter is smooth. Stop mixing as soon as the ingredients are combined.
3. Add the apples
Fold the diced apples gently into the batter with a spatula or large spoon. Use a folding motion rather than vigorous stirring so you do not overwork the flour.
4. Make the crumble topping
Add the ½ cup flour, ā cup brown sugar, and 1 teaspoon cinnamon to a small bowl. Add the 4 tablespoons cold butter. Use your fingertips or a pastry cutter to work the cold butter into the dry ingredients until you have a mixture with small and medium clumps. Do not turn it into a smooth paste.
5. Assemble and bake
Scrape the apple-filled batter into the prepared pan and spread it into an even layer. Scatter the crumble over the entire surface. Bake at 350°F for 38 to 42 minutes, until the cake is set and a skewer inserted into the cake portion comes out clean or with a few moist crumbs.
6. Rest before slicing
Let the cake cool in the pan for 15 minutes before cutting. This short rest gives the warm apples, cake, and crumble time to settle so the slices hold together better.
Tips for a Better Apple Crumble Cake
- Dice the apples fairly small so they soften within the cake’s bake time.
- Let melted butter cool slightly before combining it with the eggs so the eggs do not cook on contact.
- Mix the batter only until combined. A few tiny lumps are preferable to overmixing.
- Keep the butter cold when making the crumble so the topping stays clumpy and crisp.
- Use the skewer test in the cake portion rather than judging doneness only by the crumble, which can brown before the center is finished.
Troubleshooting
- The center is wet: Continue baking in a few-minute increments until the cake portion passes the skewer test. Oven temperatures vary.
- The crumble is browning too quickly: Loosely cover the top with foil while the center finishes baking.
- The cake is dense: The batter may have been overmixed after the flour was added. Stir only until combined next time.
- The apples are still firm: Cut them smaller and make sure the cake has reached the full bake time.
Substitutions
- Dairy-free: Use plant butter and oat milk.
- Gluten-free: Use a 1:1 gluten-free flour blend that is intended for baking.
- Apples: Choose a firm baking apple that you enjoy eating. Keep the amount at 2 medium apples so the cake’s moisture balance stays close to the original.
Storage and Reheating
Storage: Cover the cake and keep it at room temperature for up to 2 days, or refrigerate for up to 5 days.
Reheating: Warm an individual slice for about 15 seconds in the microwave, checking before adding more time.
Freezer: Wrap individual slices well and freeze for up to 2 months. Thaw in the refrigerator or at room temperature, then warm gently before serving.
Frequently Asked Questions
Can I make this ahead?
Yes. You can prepare the components up to 24 hours ahead and keep them separately covered in the refrigerator. Assemble and bake when you are ready for the best texture.
What apples work best?
A firm apple that holds its shape while baking works well. The important part is cutting the apples into evenly sized pieces so they cook at the same rate.
Why did my crumble disappear into the cake?
Make sure the crumble mixture still has visible butter clumps and scatter it over the batter rather than pressing it down. The topping should sit on the surface before baking.
Can I serve it warm?
Yes. The recipe calls for a 15-minute rest before slicing, and the cake is especially cozy served slightly warm.
