This moist coffee cake recipe makes a tender 9 x 13-inch cake layered with cinnamon-brown-sugar streusel and crunchy walnuts or pecans. Full-fat sour cream keeps the vanilla cake soft and rich, while the classic streusel adds a buttery, warmly spiced finish. It takes about 20–25 minutes to prepare and bakes at 350°F (175°C) for 45–50 minutes.
Serve this easy sour cream coffee cake for breakfast, brunch, an afternoon snack, or a relaxed dessert. Each slice has a soft crumb, a sweet cinnamon center, and a crumbly topping that tastes especially good with coffee, tea, or a cold glass of milk.
This is the kind of coffee cake that feels special without requiring complicated pastry techniques. The batter comes together with familiar pantry ingredients, and the streusel is mixed in one bowl before being layered into the cake.
Its texture is the main attraction. Sour cream contributes moisture and a gentle tang, while creamed butter and sugar create a tender, flavorful crumb. The cinnamon-brown-sugar filling breaks up the vanilla cake with pockets of sweetness and spice.
The generous 9 x 13-inch pan makes 12–16 servings, so this recipe works well for a family breakfast or a weekend gathering. For another simple variation, you can also try this easy cake mix coffee cake when you want a shortcut-style bake.
Ingredients You’ll Need
The ingredient list is divided into two simple parts: the buttery streusel and the sour-cream cake. Measuring carefully matters, especially for the flour, because too much can make the crumb heavier than intended.
Brown sugar, flour, cinnamon, and butter: These form the moist, crumbly streusel with its classic caramel-like flavor.
Walnuts or pecans: Chopped nuts add crunch and a pleasant roasted flavor. Either choice works well.
All-purpose flour, baking powder, baking soda, and salt: This combination provides structure, lift, and balanced seasoning.
Softened butter and granulated sugar: Beating them together introduces air and gives the cake a lighter crumb.
Eggs and vanilla: Eggs bind the batter, while vanilla rounds out the buttery flavor.
Full-fat sour cream: This is the key to a moist, tender cake and supplies acidity for the baking soda.
Room-temperature butter should be soft enough to press gently with a fingertip but not melted. Room-temperature eggs blend more evenly into the creamed butter mixture, which helps the batter rise consistently.
How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C), then grease a 9 x 13-inch baking pan. If you want especially easy serving and cleanup, line the bottom with parchment paper while leaving enough paper extending slightly over the sides to help lift the cake later.
Step 2: Prepare the streusel first by combining the packed brown sugar, flour, chopped walnuts or pecans, and cinnamon. Stir in the melted butter until the mixture resembles coarse, moist crumbs; do not try to turn it into a smooth paste.
Step 3: In a separate bowl, whisk together the 3 cups of flour, baking powder, baking soda, and salt. Whisking distributes the leaveners and salt so the cake rises evenly without concentrated pockets of baking soda.
Step 4: Beat the softened butter and granulated sugar for about 2–3 minutes. Stop when the mixture looks light and creamy, scraping down the sides of the bowl once or twice so the butter is evenly incorporated.
Step 5: Add the eggs one at a time, beating after each addition. Mix in the vanilla extract, and pause to scrape the bowl if the mixture collects around the edges.
Step 6: Add the dry ingredients in two or three additions, alternating with the sour cream. Begin and end with the dry ingredients, mixing only until no dry streaks remain; excessive mixing can make the cake dense or chewy.
Step 7: Spread half of the batter across the prepared pan. The batter is thick, so use an offset spatula or the back of a spoon to guide it into the corners without flattening it aggressively.
Step 8: Sprinkle approximately half of the streusel evenly over the first layer of batter. Keep the filling distributed from edge to edge so each portion receives a cinnamon layer.
Step 9: Carefully spread the remaining batter over the streusel, then scatter the rest of the streusel across the top. Work gently with an offset spatula or spoon so the second layer of batter does not mix heavily with the filling beneath it.
Step 10: Bake for 45–50 minutes, checking the cake near the end of the baking time. It is ready when the center is set and a toothpick inserted into the cake portion, rather than directly into a thick streusel pocket, comes out with only a few moist crumbs.
Step 11: Cool the cake in the pan for at least 20 minutes before cutting. For neater squares and a more settled filling, allow it to cool longer before slicing.
Pro Tips for a Moist Crumb
Full-fat sour cream is the best choice for this recipe because its richness and moisture support the soft texture. Lower-fat products may change the consistency of the batter, so use the full-fat version listed in the recipe whenever possible.
Do not overmix once the flour enters the bowl. A few small, harmless streaks can disappear as you finish folding, but stop as soon as the ingredients are combined.
Pay attention to butter temperature. Melted butter cannot trap air during creaming, while cold butter will not blend smoothly with the sugar. Softened butter and room-temperature eggs create a more cohesive batter.
If the top begins to brown before the center is finished, loosely cover the pan with foil during the final portion of baking. Avoid opening the oven repeatedly, since temperature changes can affect the cake’s rise.
Let the baked cake cool before judging its texture. The crumb continues to settle as it cools, and cutting immediately can cause the center layer to appear less structured than it will be later.
Serving Ideas and Flavor Pairings
Serve thick squares plain, or dust them lightly with powdered sugar after the cake has cooled. The soft vanilla crumb and cinnamon topping are already flavorful, so a simple presentation keeps the streusel at the center of attention.
For brunch, arrange the slices on a platter with fresh berries and hot coffee. For dessert, add a spoonful of softly whipped cream or a small scoop of vanilla ice cream.
This recipe is also a useful starting point for other fruit-forward bakes. If you enjoy tender cakes with dried fruit, see this moist fruit cake recipe for a different style of celebratory treat.
Storage and Reheating
Keep the cooled cake covered so the exposed crumb does not dry out. It can be served at room temperature, where the butter and cinnamon flavors are most noticeable, or gently warmed for a softer, just-baked feel.
For longer storage, refrigerate the covered cake. Let individual slices come closer to room temperature before serving, or warm them briefly and carefully so the streusel remains pleasant rather than hard.
When preparing the cake ahead, cool it completely before covering. Trapping heat under a lid can create condensation on the streusel and soften its crumbly texture.

Moist Coffee Cake Recipe
A tender vanilla sour-cream coffee cake layered with cinnamon-brown-sugar streusel and chopped nuts. This easy 9 x 13-inch cake makes 12–16 servings and is ideal for breakfast, brunch, or dessert.
Heat the oven to 350°F (175°C). Grease a 9 x 13-inch baking pan, and line the bottom with parchment paper if desired.
Combine the brown sugar, flour, chopped walnuts or pecans, and cinnamon for the streusel. Stir in the melted butter until coarse, moist crumbs form, then set aside.
Whisk the flour, baking powder, baking soda, and salt in a separate bowl.
Beat the softened butter and granulated sugar for 2–3 minutes, until light and creamy.
Beat in the eggs one at a time, then mix in the vanilla extract.
Add the dry ingredients in two or three additions, alternating with the sour cream. Mix only until no dry streaks remain.
Spread half of the batter in the prepared pan and sprinkle approximately half of the streusel evenly over it.
Gently spread the remaining batter over the streusel, then cover the top with the remaining streusel.
Bake for 45–50 minutes, until the center is set and a toothpick inserted into the cake portion comes out with only a few moist crumbs.
Cool the cake in the pan for at least 20 minutes before cutting. It becomes easier to slice after cooling further.
Notes
Use full-fat sour cream and room-temperature eggs and butter for the smoothest batter and best texture. Avoid overmixing after adding the flour. Store covered at room temperature for a short period or refrigerate for longer storage; bring chilled slices closer to room temperature before serving.
