I’ll walk you through shopping, the exact stepwise method, common pitfalls, sensible substitutions, and how to store and reheat leftovers so each slice stays as good as the first. No fluff—just practical tips that make the bake dependable every time.
Shopping List
Grab everything on this short list so the bake goes smoothly. I group items by location in the store to save you time at the grocery aisle.
- Dry goods: all-purpose flour, brown sugar, cane sugar, baking powder, baking soda, sea salt, cinnamon.
- Dairy & eggs: unsalted butter, whole milk Greek yogurt, large eggs, vanilla extract.
- Equipment check: you’ll need a 9×13-inch baking dish, measuring cups and spoons, mixing bowls, and a mixer or strong whisk.
Ingredients
- ⅓ cup brown sugar — used in the filling; provides molasses warmth and moisture.
- ¼ cup cane sugar — balances the brown sugar in the filling for brightness.
- 1 teaspoon cinnamon — essential spice for the filling’s signature flavor.
- ⅔ cup all-purpose flour (spooned and leveled) — for the crumble topping; measured by spooning into the cup to avoid packing.
- ⅓ cup brown sugar — in the crumble topping for deeper caramel notes.
- ¼ cup cane sugar — in the crumble to add crispness and sweetness balance.
- 1 teaspoon cinnamon — heats the crumble with the same warm spice as the filling.
- 5 tablespoons unsalted butter, at room temperature — binds the crumble and creates tender, sandy bits.
- 2½ cups plus 2 tablespoons all-purpose flour (spooned and leveled) — main structure for the cake batter; spoon and level for accuracy.
- 1½ teaspoons baking powder — gives lift to the cake.
- 1½ teaspoons baking soda — reacts with yogurt to ensure proper rise and tenderness.
- ¾ teaspoon sea salt — enhances overall flavor; use measured sea salt for consistency.
- ¾ cup unsalted butter, at room temperature — creamed with sugar to create a light, rich batter.
- 1½ cups cane sugar — primary sweetener for the cake batter; provides structure and caramelization.
- 3 large eggs — add richness and structure; room temperature eggs incorporate better.
- 1½ teaspoons vanilla extract — lifts the flavor and rounds the sweetness.
- 1½ cups whole milk Greek yogurt — the moisture and tang that keep the crumb tender and flavorful.
Stepwise Method: Coffee Cake
- Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking dish.
- Make the filling: In a small bowl, stir together 1/3 cup brown sugar, 1/4 cup cane sugar, and 1 teaspoon cinnamon. Set aside.
- Make the crumble topping: In a medium bowl, combine 2/3 cup all-purpose flour (spooned and leveled), 1/3 cup brown sugar, 1/4 cup cane sugar, and 1 teaspoon cinnamon. Add 5 tablespoons unsalted butter (at room temperature) and use a spatula to press and mix until there is no dry flour remaining and the mixture is crumbly. Do not overmix. Set aside.
- Whisk the dry cake ingredients in a large bowl: 2 1/2 cups plus 2 tablespoons all-purpose flour (spooned and leveled), 1 1/2 teaspoons baking powder, 1 1/2 teaspoons baking soda, and 3/4 teaspoon sea salt. Set this dry mixture aside.
- In the bowl of a stand mixer or a large bowl with an electric mixer, cream 3/4 cup unsalted butter (at room temperature) until smooth.
- Add 1 1/2 cups cane sugar to the creamed butter and beat until combined and slightly fluffy.
- Add the 3 large eggs one at a time, beating well after each addition. Stir in 1 1/2 teaspoons vanilla extract.
- Add the dry mixture and the 1 1/2 cups whole milk Greek yogurt to the butter mixture in alternating additions: add one quarter of the dry mixture and mix just to combine, then add one third of the yogurt and mix. Repeat this sequence (dry, yogurt, dry, yogurt, dry, yogurt), ending with the remaining quarter of the dry mixture. Mix only until the ingredients are incorporated; do not overmix.
- Spread half of the batter evenly in the bottom of the prepared 9×13-inch pan.
- Evenly sprinkle the prepared filling (from step 2) over the batter layer.
- Dollop the remaining batter in spoonfuls over the filling, then use a spatula or an offset knife to carefully spread it into an even layer without mixing it into the filling.
- Evenly sprinkle the crumble topping over the top of the cake.
- Bake for 45 to 50 minutes, or until a toothpick inserted into the center comes out clean.
Why Cooks Rave About It
There’s a reason this style of coffee cake is a staple: it hits texture and flavor notes that feel universally satisfying. The cake is tender thanks to the yogurt and balanced leavening. The mid-layer filling gives a concentrated ribbon of cinnamon-sweetness in every bite, and the crumble topping adds contrasting crunch and buttery flavor.
It’s also very forgiving. The method separates filling and crumble early, which keeps preparation tidy and reduces risk of overworking the batter. From a practical standpoint, it travels well, slices cleanly once cooled, and is intuitive for bakers who want a consistent, comforting result without fuss.
Healthier Substitutions
- Reduce cane sugar in the batter slightly if you prefer less sweetness—start by cutting 1/4 cup and test to taste.
- Swap whole-milk Greek yogurt for a lower-fat plain Greek yogurt to cut fat while keeping moisture and tang.
- Use light brown sugar instead of dark if you want a milder molasses flavor in the filling and crumble.
- For a gluten-free option, use a 1:1 gluten-free baking flour blend, but expect subtle texture differences; check the blend’s starch content for best results.
Tools of the Trade
- 9×13-inch baking dish — the recipe’s bake time and texture rely on this pan size.
- Stand mixer or electric hand mixer — speeds creaming and ensures even incorporation of eggs.
- Mixing bowls (small, medium, large) — keep filling, crumble, dry, and wet ingredients separate for efficiency.
- Spatula and offset knife — for spreading batter gently over the filling without mixing layers.
- Measuring cups and spoons — spoon and level flour; accuracy matters here for texture.
- Toothpick — for the simple doneness check in the center of the cake.
Steer Clear of These
- Overmixing the batter — it develops gluten and makes the cake tough. Mix only until combined, especially after adding dry ingredients.
- Using cold butter for creaming — it won’t incorporate properly. Bring butter to room temperature for a smooth cream.
- Packing the flour into the cup — spoon flour into the cup and level it to avoid a dense cake.
- Ignoring the spread technique — when you dollop the remaining batter over the filling, work gently. Forceful spreading can tear through the filling and create a marbled mess.
Dietary Customizations
Simple swaps can tailor this cake to preferences or restrictions. For a dairy-free version, replace the butter with a high-quality vegan butter and use a nondairy strained yogurt for the batter—expect small changes in flavor and browning. To make it vegan, also replace eggs with neutral egg replacers or a flaxseed mixture, but be mindful that structure and rise can change; add a little extra leavening if needed and test for texture.
For lower-sugar diets, reduce the sugar amounts gradually and consider adding a splash more vanilla or a grated citrus zest to keep the flavor bright without extra sweetness.
Cook’s Commentary
I love this recipe because the structure is straightforward but the finish is satisfying—big contrast between tender cake and crunchy crumble. A couple of personal tips: always make the crumble with room-temperature butter and mix just until crumbly; a cold crumble won’t press together right and an overworked crumble can be greasy. Also, when layering, use an offset knife to coax the top batter into place. That careful spread keeps the filling concentrated and gives the layered look we all expect.
Oven temperatures vary—mine runs slightly hot, so I check the cake at 40 minutes the first time I bake it in a new oven. Look for even browning and the toothpick test to be sure the center is set.
Storage & Reheat Guide
Let the cake cool completely in the pan on a rack before storing. For short-term storage, cover the pan tightly with foil or plastic wrap and keep at room temperature for up to 2 days. For longer storage, refrigerate up to 5 days or freeze portions for up to 3 months—wrap slices individually in plastic then foil to prevent freezer burn.
To reheat, remove from the refrigerator and microwave a single slice for 15–25 seconds depending on microwave power, or warm in a 325°F oven for 8–12 minutes until heated through. If frozen, thaw overnight in the fridge, then warm gently as above. Reheating briefly helps revive the crumble’s texture without drying the cake.
Your Questions, Answered
- Q: Can I use sour cream instead of Greek yogurt? A: Yes. Sour cream is a fine substitute and will provide similar moisture and tang.
- Q: What if the top browns too quickly? A: Tent the pan loosely with foil for the last 10–15 minutes of baking to prevent over-browning while the center finishes.
- Q: Can I halve the recipe? A: You can, but you’ll need to adjust baking time and use a smaller pan (an 8×8-inch pan is common). Check doneness early and often.
- Q: Why both baking powder and baking soda? A: They work together: baking powder provides general lift, while baking soda reacts with the yogurt for additional rise and tenderness.
Let’s Eat
Slice this cake thick and serve warm or at room temperature. It’s perfect with a cup of coffee, but it’s also excellent with tea or a tall glass of milk. If you want to dress it up, a light dusting of powdered sugar or a simple vanilla glaze complements without stealing attention from the cinnamon ribbon and buttery crumble.
Make it for a morning gathering or to keep in the kitchen for a few days of sweet, reliable slices. Follow the steps, mind the small tips, and you’ll have a coffee cake that disappears fast—every time.
