Baking an Easy Peach Crumb Cake
The smell of cinnamon bubbling into melted sugar is what hits you first. Then comes that bright, jammy scent of peaches softening in the oven. I remember the first time I tried a crumb cake, and the topping was just a soggy layer of flour. It took me a while to realize that the temperature of the butter is everything.
This Easy Peach Crumb Cake relies on the contrast between a soft, moist sponge and a rugged, crunchy lid. It's the kind of bake that feels rustic and unpretentious, making it great for guests or just a quiet Tuesday.
You can expect a cake that holds its shape but stays tender. The peaches don't just sit there; they sink slightly into the batter, creating little pockets of fruit juice. It's a balanced sweetness that doesn't overwhelm the palate.
Why This Cake Works
Greek Yogurt: The acidity breaks down gluten for a more tender crumb. It also adds a subtle tang that cuts through the sugar.
Cornstarch: Mixing this with the fruit prevents the peaches from releasing too much water. According to King Arthur Baking, starch helps stabilize fruit juices during the bake.
Cold Butter: Keeping the fat cold prevents the topping from melting into a flat sheet. It creates those distinct, pea sized lumps that brown beautifully.

The Cake Base
- 250g all purpose flour Why this? Provides the structure for a sturdy slice
- 150g coconut sugar Why this? Adds a deep, caramel like sweetness
- 5g baking powder
- 3g baking soda
- 1.5g salt
- 120g plain Greek yogurt Why this? Ensures the cake stays moist
- 120ml unsweetened almond milk
- 1 large egg
- 5ml vanilla extract
- 28g melted coconut oil
The Fruit Layer
- 450g fresh peaches, peeled and sliced Why this? Fresh fruit provides a bright, natural acidity
- 8g cornstarch
- 2g ground cinnamon

- 95g all purpose flour
- 100g coconut sugar
- 2g ground cinnamon
- 55g cold unsalted butter, cubed Why this? Cold fat creates a pebbly, crisp texture
Simple Tools Needed
You don't need a professional kitchen for this. A couple of bowls and a whisk will do the job. I usually use a standard 13x9-inch baking pan, which is the gold standard for these kinds of rustic bakes.
If you don't have a pastry cutter, don't sweat it. Two forks pressed together work just as well to cut the butter into the flour. The goal is just to get those small lumps of fat.
Step-by-step Process
Phase 1: The Foundation
- Preheat your oven to 175°C (350°F). Grease a 13x9-inch baking pan and line it with parchment paper Note: This makes lifting the cake much easier.
- Toss the 450g sliced peaches with 8g cornstarch and 2g cinnamon in a medium bowl. Let them sit while you do the rest.
Phase 2: Mixing the Batter
- Whisk 250g flour, 150g coconut sugar, baking powder, baking soda, and salt in a large bowl.
- In a separate bowl, mix the 120g Greek yogurt, 120ml almond milk, egg, and vanilla extract.
- Stir the wet ingredients into the dry flour mixture until just combined. Stop as soon as the flour streaks disappear to avoid a tough cake.
Phase 3: Layering and Baking
- Spread the batter evenly into the pan.
- Layer the cinnamon peach slices on top of the batter.
- Mix 95g flour, 100g coconut sugar, and 2g cinnamon in a bowl. Cut in the 55g cold cubed butter using forks until you see pea sized lumps.
- Sprinkle the crumble topping evenly over the peach layer.
- Bake for 55 minutes until the topping is mahogany colored and the cake is set.
Chef's Note: If the edges are browning too fast but the center is still wobbly, tent the pan with foil for the last 10 minutes.
Fixing Common Issues
The most common issue with an Easy Peach Crumb Cake is the fruit. If you don't use enough cornstarch, the peaches leak, and you end up with a soggy middle.
Troubleshooting Common Issues
| Issue | Solution |
|---|---|
| Why Your Peaches Sink | If the batter is too thin or the peaches are too heavy, they might dive to the bottom. This usually happens if the yogurt is too watery. Use a thick, strained Greek yogurt to provide more support. |
| Why Your Crumble is Soft | If the butter was too warm when you mixed it, the topping will melt into the cake. Always use butter straight from the fridge. |
| Why the Cake Cracked | A crack in the middle usually means the oven was too hot. Ensure your oven is calibrated to 175°C. |
Customizing Your Cake
You can easily swap fresh peaches for canned ones. Just drain them well and pat them dry with a paper towel first. The flavor is more concentrated and syrupy, which makes for a very rich Easy Peach Crumb Cake.
If you're in the mood for something different, try adding a handful of oats to the crumble topping for a nuttier texture. For those who love a little extra zest, a teaspoon of lemon juice mixed into the peaches brightens the whole dish.
If you need more ideas for a brunch spread, these Homemade Biscuits are a great savory side to balance the sweetness of the cake. For another sweet treat to keep in the jar, my Peanut Butter Cookies are always a hit.
Decision Shortcut
- Want more crunch? Add 30g of rolled oats to the crumble.
- Want it tarter? Add 1 tsp of lemon zest to the batter.
- Need a faster bake? Use canned peaches and a smaller 8x8 pan (reduce bake time to 35-40 mins).
Adjusting the Batch Size
Scaling this recipe is straightforward, but baking is a bit of a science. If you're making a half batch, use an 8x8-inch pan and reduce the baking time by about 20%. Since you can't easily halve an egg, beat one egg in a cup and use about 2 tablespoons.
When doubling the Easy Peach Crumb Cake, don't just double the spices. Salt and cinnamon can become overwhelming, so increase them by only 1.5x. Use two 13x9 pans rather than one deep one.
If you must use a deeper pan, lower the oven temp to 150°C (325°F) and extend the time by 15-20 minutes to ensure the middle cooks through.
| Batch Size | Pan Size | Temp Change | Time Adjustment |
|---|---|---|---|
| Half (1/2) | 8x8 inch | None | -20% time |
| Double (2x) | 2x 13x9 inch | None | Same time |
| Double (2x) | Deep pan | -25°F / -20°C | +15-20 mins |
Busting Baking Tales
Some people think that searing the fruit in a pan first is necessary for flavor. It's not. The oven does all the work, caramelizing the sugars as the peaches roast on top of the batter.
Another myth is that you should cream the butter and sugar for the crumble. Actually, the goal is to avoid a smooth emulsion. You want distinct chunks of fat to create those crispy pockets in the crust.
Storage and Freshness
This cake stays moist thanks to the yogurt, but it's best kept in an airtight container. At room temperature, it lasts about 2 days. In the fridge, it'll stay good for 5 days, but the crumble may soften slightly.
For longer storage, you can freeze the Easy Peach Crumb Cake. Slice it first, wrap each piece in parchment paper, and place them in a freezer bag. They last up to 3 months. To reheat, pop a slice in the oven at 175°C for 5-10 minutes to bring back the crispiness.
To avoid waste, don't throw away the peach peels. If you have a lot of them, simmer them with a bit of sugar and water to make a simple peach syrup for pancakes.
Serving and Styling
For a cafe style finish, let the cake cool completely before slicing. This prevents the fruit from sliding off. Cut into 2x3 inch rectangles for a clean, professional look.
Serving this warm with a dollop of cold whipped cream or a scoop of vanilla bean ice cream is the way to go. The contrast of the hot, jammy peaches and the cold cream is brilliant. If you're serving it for breakfast, a drizzle of maple syrup over the crumble adds a nice touch of richness.
Keep the slices simple. A light dusting of powdered sugar over the mahogany crust adds a bit of visual pop without adding too much sweetness. Enjoy it while the cake is still slightly warm from the oven.
Recipe FAQs
How to make a simple peach cake?
Whisk dry and wet ingredients separately, combine them, and top with sliced peaches and crumble. Bake at 350°F (175°C) for 55 minutes until the topping is mahogany colored and the cake is set.
How to make the peach crumble topping?
Mix flour, coconut sugar, and cinnamon, then cut in cold cubed butter. Use a pastry cutter or forks until pea-sized lumps remain before sprinkling the mixture over the peach layer.
Why did my peaches sink to the bottom of the cake?
The batter was likely too thin. This usually happens if the Greek yogurt is too watery; use a thick, strained variety to provide more support for the fruit slices.
