Cinnamon Sugar Peach Snack Cake

Make this gluten-free cinnamon sugar peach snack cake with fresh peaches, Greek yogurt, and a golden cinnamon topping. Step-by-step instructions, storage tips, and easy variations.

Peach season hits fast and leaves even faster, and I learned that the hard way the summer I waited too long to bake with the haul from my neighbor’s tree. I threw together this gluten-free cinnamon sugar peach snack cake in a mild panic, and it turned out to be the best thing I baked all year.

The cinnamon sugar crust that bakes on top crackles just slightly when you press it with a finger—like the top of a good coffee cake but with that warm, jammy peach hiding in every bite.

This is the kind of cake you cut straight from the pan at room temperature, no plates required. It travels well, slices cleanly, and disappears faster than you’d expect from something this unfussy.

Why You’ll Love This Cinnamon Sugar Peach Snack Cake

• Texture and flavor: Moist and tender crumb from Greek yogurt, with pockets of soft peach and a lightly crisp cinnamon sugar top that sets beautifully as it cools.
• Difficulty level: One bowl for the wet ingredients, one for the dry—no stand mixer required, and no complicated techniques.
• Naturally adaptable: Works dairy-free with simple swaps, and the topping is endlessly riffable without touching the base recipe.
• Best when: Peaches are at peak ripeness in summer, but frozen peaches make this a year-round easy dessert option that doesn’t sacrifice flavor.

The Secret to Perfect Gluten-Free Cinnamon Sugar Peach Snack Cake

• Room-temperature eggs and butter matter: Cold eggs can cause the batter to curdle and gluten-free batters are less forgiving than wheat-based ones. Letting both come to room temp before mixing keeps everything smooth and evenly emulsified.
• Greek yogurt is load-bearing: It adds moisture, a gentle tang, and structure that compensates for the lack of gluten. Don’t skip it or thin it out—it’s doing real work here.
• Fold, don’t stir, the peaches in: Overmixing after adding fruit breaks down the peach cubes and releases excess liquid, which can make the center of the cake gummy. A few gentle folds are all you need.
• Brush butter before the cinnamon sugar: This anchors the topping so it bakes into a cohesive crust rather than sliding off or baking into a patchy layer. It’s the detail that makes the top look bakery-finished.

Ingredients

Cake Batter

Ingredient	Amount	Notes
Certified gluten-free all-purpose flour	2 cups	Certified GF label matters—cross-contamination is a real risk with generic flours
Certified gluten-free baking powder	2 teaspoons	Check the label; some brands contain gluten-based starch
Baking soda	½ teaspoon
Fine sea salt	½ teaspoon
Ground cinnamon	1½ teaspoons	Use fresh-smelling cinnamon—old spice loses its punch
Ground nutmeg	½ teaspoon	Freshly grated is noticeably more aromatic
Unsalted butter, softened	½ cup	Must be fully softened, not melted
Granulated sugar	½ cup
Light brown sugar	¼ cup	Adds moisture and a subtle molasses note
Large eggs, room temperature	2
Vanilla extract	1 teaspoon
Plain Greek yogurt or sour cream	½ cup	Full-fat gives the best result
Milk (if needed)	2 tablespoons	Add one tablespoon at a time only if batter is too stiff to spread
Fresh peaches, peeled and diced	2 cups	About 2–3 medium peaches; frozen works too (thaw and pat dry first)

Cinnamon Sugar Topping

Ingredient	Amount	Notes
Granulated sugar	2 tablespoons
Ground cinnamon	1 teaspoon
Melted butter	1 tablespoon	Brushed on top to anchor the sugar crust

Optional Garnishes

• Powdered sugar
• Vanilla glaze
• Whipped cream
• Fresh peach slices
• Chopped pecans

Instructions

Prep the Pan and Oven

1. Preheat and prepare. Preheat the oven to 350°F (175°C). Grease and line an 8×8-inch square baking pan with parchment paper, leaving a little overhang on two sides so you can lift the cake out cleanly after baking.

Mix the Batter

2. Whisk the dry ingredients. In a medium bowl, whisk together the gluten-free flour, baking powder, baking soda, salt, cinnamon, and nutmeg until evenly combined. Whisking distributes the leaveners so the cake rises evenly rather than doming on one side.
3. Cream the butter and sugars. In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar together until light and fluffy—about 2–3 minutes. The mixture should look pale and slightly airy; this step builds the structure that holds the cake together without gluten.
4. Add the eggs and vanilla. Beat in the eggs one at a time, making sure the first is fully incorporated before adding the second. Mix in the vanilla extract. The batter should look smooth and cohesive at this stage.
5. Fold in the Greek yogurt. Add the Greek yogurt and mix until smooth. This is what keeps the crumb moist and tender even after the cake cools completely.
6. Combine wet and dry. Gradually fold the dry ingredients into the wet ingredients using a spatula. If the batter looks too thick to spread easily, stir in the milk one tablespoon at a time until it reaches a spreadable consistency. Don’t add both tablespoons automatically—check the texture first.
7. Fold in the peaches. Gently fold in the diced peaches with just a few strokes. You want the fruit distributed without breaking it down—overmixing here releases liquid that can sink the center of the cake.

Top and Bake

8. Fill the pan. Spread the batter evenly into the prepared baking pan using a spatula or the back of a spoon. Getting an even layer ensures the cake bakes through at the same rate edge to center.
9. Brush with butter and add the topping. Brush the top of the batter lightly with the 1 tablespoon of melted butter. Mix the 2 tablespoons of granulated sugar and 1 teaspoon of cinnamon together, then sprinkle the mixture evenly over the entire surface.
10. Bake until golden. Bake for 35–40 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. The edges will pull slightly away from the pan, and the cinnamon sugar top will have set into a light, crackling crust.
11. Cool before slicing. Allow the cake to cool in the pan for 15 minutes, then transfer to a wire rack to cool completely. Slicing too early—before the structure sets—can cause the crumb to collapse, especially in the center where the peaches are densest.
12. Finish and serve. Dust with powdered sugar or drizzle with vanilla glaze before serving if desired. A handful of chopped pecans over the top adds crunch that plays really well against the soft peach interior.

Make It Your Own

You know… one of the things I love most about this gluten-free peach cake is how well it takes to substitutions without losing what makes it work.

Dairy-free version: Swap the butter for a good-quality vegan butter (same amount, same method), and replace the Greek yogurt with a full-fat dairy-free coconut yogurt. The result is slightly richer and just as moist—this swap works because coconut yogurt has a similar fat content and acidity to the original.

Frozen peaches: Thaw completely and pat very dry with paper towels before folding in. Excess liquid from frozen fruit is the most common reason this cinnamon sugar snack cake comes out gummy in the center—drying them thoroughly solves it completely.

Swap the fruit: Diced nectarines, plums, or blueberries all work well in the same quantities. Berries release more juice than peaches, so reduce milk to zero when using them—the batter won’t need it.

Add a streusel topping: Mix 3 tablespoons gluten-free oats, 2 tablespoons brown sugar, and 1 tablespoon cold butter cut into small pieces. Scatter this over the cinnamon sugar layer before baking for a thicker, crunchier crown. According to the Beyond Celiac gluten-free diet guide, certified gluten-free oats are safe for most people with celiac disease, though some individuals remain sensitive—know your tolerance before adding them.

Spice it differently: Replace the nutmeg with cardamom for a more floral, slightly exotic profile. Or add ¼ teaspoon of ground ginger alongside the existing spices—it sharpens the cinnamon without taking over.

Common Problems & Solutions

Problem: The center of the cake is gummy or underdone. This almost always comes from too much liquid—either from wet peaches or over-measuring the milk. Solution: pat fruit very dry before folding in, and only add milk if the batter genuinely won’t spread. Bake to 40 full minutes and test with a toothpick in two spots, not just one.

Problem: The cinnamon sugar topping sank into the batter. This happens when the butter brush is too heavy, making the surface too slick for the sugar to grip. Solution: use just a thin layer of melted butter—enough to coat, not saturate—then sprinkle immediately before the butter cools and absorbs.

Man, oh man… this one caught me off guard the first time I made it for a Labor Day potluck. The top looked bare coming out of the oven because I’d been too generous with the butter. Now I use a pastry brush and go light-handed.

Problem: The cake crumbles when sliced. Gluten-free batters need more cooling time than wheat-based ones before slicing. Solution: wait the full 15 minutes in the pan, then let the cake cool at least 30 more minutes on the rack before cutting. The structure continues to set as it cools.

Problem: The cake domed and cracked on top. Too much leavening or an oven running hot can cause this in gluten-free baking. Solution: verify your baking powder is fresh (drop a teaspoon in hot water—it should bubble vigorously), and use an oven thermometer to check actual temperature. The USDA food safety temperature guidelines are a useful reference for understanding how oven calibration affects baked goods.

Storage & Meal Prep

Method	Duration	Notes
Counter	2–3 days	Airtight container; keeps the cinnamon top from softening too quickly
Fridge	5–7 days	Bring to room temperature before serving for best texture
Freezer	2–3 months	Wrap individual slices tightly; thaw at room temperature overnight

To reheat a cold slice, microwave for 15–20 seconds—just enough to take the chill off without drying out the crumb. A warm slice with a small spoonful of whipped cream on top is honestly one of the better versions of this easy dessert.

For meal prep, bake the full batch and freeze individual slices wrapped in plastic wrap then foil. Pull them out the night before you want them and let them thaw on the counter—you’ll have a ready-made snack without any extra effort during the week.
