Fresh Peach Coffee Cake with Cinnamon Crumble

This peach coffee cake is the kind of easy, not-too-sweet breakfast cake that turns a summer morning into something special.

Ripe peach slices bake into a soft, sour cream cake under a brown sugar and cinnamon crumble. It’s the treat I pull out when I need something that feels a little fancier than a muffin but requires almost no extra work.

Why This Coffee Cake Works

The sour cream keeps the cake tender for days, so you can make it the night before and it’s still moist in the morning.

The cinnamon crumble is buttery and crisp on top, with a little extra tucked into the center of the batter. It gives every bite a salty-sweet contrast that works beautifully with the juicy peaches.

Ingredients

• 2 cups all-purpose flour: spoon and level for accurate measuring
• 2 teaspoons baking powder: helps the cake rise evenly
• 1/2 teaspoon baking soda: works with the sour cream for a tender crumb
• 1/4 teaspoon salt: balances the sweetness
• 1/2 cup (1 stick) unsalted butter, softened: brings richness to the cake
• 3/4 cup granulated sugar: sweetens the batter just enough
• 2 large eggs: give structure and moisture
• 1 cup full-fat sour cream: the key to a soft, moist cake
• 1 teaspoon vanilla extract: rounds out the flavor
• 2 cups sliced peeled fresh peaches: about 2 medium peaches

For the Crumble

• 3/4 cup all-purpose flour: spoon and level
• 1/2 cup packed brown sugar: light or dark both work
• 1 teaspoon ground cinnamon: adds warmth and spice
• 6 tablespoons cold unsalted butter, cut into small cubes: creates a craggy, crisp topping

Variations / Substitutions

• Use plums or nectarines instead of peaches: same amount, just slice them about the same thickness.
• Frozen peach slices work: no need to thaw, just scatter them straight from the freezer.
• Dairy-free version: swap the sour cream for a thick plant-based sour cream and use vegan butter sticks; the crumble will still crisp.
• A little crunch: mix 1/2 cup chopped pecans or walnuts into the crumble before baking.

How to Make Peach Coffee Cake

Step 1: Make the Cinnamon Crumble

Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan. In a medium bowl, stir together 3/4 cup all-purpose flour, 1/2 cup packed brown sugar, and 1 teaspoon cinnamon. Add the 6 tablespoons cold butter cubes and rub them into the dry ingredients with your fingertips until the mixture looks like coarse crumbs with some pea-sized bits.

The crumble should hold together when squeezed but still fall apart easily. Set it aside while you mix the cake.

Step 2: Whisk the Dry Ingredients

In a separate bowl, whisk together 2 cups flour, 2 teaspoons baking powder, 1/2 teaspoon baking soda, and 1/4 teaspoon salt.

This step gets the leavening evenly distributed so you don’t end up with any unpleasant pockets of baking powder in the baked cake.

Step 3: Cream the Butter and Sugar

In a large bowl, beat the softened 1/2 cup butter and 3/4 cup granulated sugar with an electric mixer on medium speed until light and fluffy, about 2 minutes. Beat in the 2 eggs, one at a time, then the 1 cup sour cream and 1 teaspoon vanilla.

The mixture may look a little curdled after adding the sour cream; that’s normal and will smooth out once the dry ingredients go in.

Step 4: Layer the Batter and Peaches

With the mixer on low, gradually add the flour mixture to the wet ingredients, mixing just until no dry streaks remain. Spread half the batter into the prepared pan. Scatter half the sliced peaches evenly over the batter, then sprinkle half the crumble on top. Carefully spread the remaining batter over the crumble, top with the rest of the peaches, and finish with the remaining crumble.

Don’t worry about the batter covering the crumble perfectly; it’s a rustic cake and any exposed crumble gets extra crisp in the oven.

Step 5: Bake and Slice the Cake

Bake the cake on the middle rack for 40 to 45 minutes, until the top is deeply golden and a toothpick inserted in the center comes out with just a few moist crumbs. Let the cake cool in the pan on a wire rack for at least 30 minutes before slicing.

Dust with powdered sugar if you like, then cut into squares and serve warm or at room temperature.

Tips for a Tender Peach Coffee Cake

• Bring cold ingredients to room temperature: set out the eggs and sour cream about 30 minutes before you start so they blend smoothly into the batter.
• Pat juicy peaches dry: if your peach slices release a lot of juice, give them a quick blot with a paper towel so they don’t make the cake soggy.
• Stop mixing as soon as the flour disappears: overmixing the batter can make the cake dense and rubbery.
• Check for doneness with a toothpick: the cake is ready when the toothpick has a few moist crumbs attached. A clean toothpick means it may already be a bit overbaked.
• Use a serrated knife for clean slices: the crumble can crack a smooth-edged knife; a serrated blade cuts through it neatly.

Bake times shift a little depending on your pan.

Storing Leftover Coffee Cake

• Refrigerate: keep the cake covered at room temperature for up to 2 days, or in the fridge for up to 5 days. The fridge will firm up the crumb slightly, but the flavor stays good.
• Reheating: warm individual slices in the microwave for about 20 seconds to soften the cake and revive the crumble’s crisp edge.
• Serve cold: straight from the fridge, it’s still tender and makes a refreshing snack on a warm afternoon.

What to Serve With Peach Coffee Cake

A thick slice next to a hot cup of coffee or spiced chai feels just right for a slow morning. When dessert is the plan, a small scoop of vanilla ice cream melts into the warm cake beautifully. For a bigger brunch spread, add a bowl of fresh berries and some scrambled eggs.

Frequently Asked Questions

Can I use frozen or canned peaches?

Yes. Frozen peach slices can go in straight from the freezer; no need to thaw. Canned peaches should be drained well and patted dry so they don’t water down the cake.

My crumble sank into the batter; what went wrong?

It likely got too fine. Keep some pea-sized butter bits in the crumble when you rub it together, and be gentle when you spread the top batter layer so the crumble stays on the surface.

Can I freeze this coffee cake?

Yes. Wrap the completely cooled cake tightly in plastic wrap and foil, then freeze for up to 3 months. Thaw overnight in the fridge and bring to room temperature or warm slices before serving.

Can I make this dairy-free?

You can. Use a thick plant-based sour cream and stick-style vegan butter. The texture will be slightly less rich but the cake will still be tender and the crumble will still crisp up.

Notes

The cake stays moist at room temperature for 2 days or in the fridge for up to 5. For the cleanest slices, use a serrated knife and wipe it between cuts.
