This easy Yellow Cake Mix Coffee Cake Recipe combines a box of yellow cake mix, instant vanilla pudding, sour cream, eggs, and vegetable oil to create a tender, moist cake with very little effort. A cinnamon, brown sugar, and pecan topping is layered through the batter and sprinkled over the top before baking at 350°F for 45–50 minutes in a greased 9-by-13-inch dish.
The finished coffee cake is soft and buttery-tasting, with a fragrant cinnamon-sugar middle and a lightly crisp nut topping. It is a dependable choice for breakfast, brunch, afternoon coffee, holidays, or any time you want a homemade cake without measuring a long list of dry ingredients.
This yellow cake mix coffee cake is one of those recipes that tastes far more thoughtful than the effort required. The cake mix provides a reliable base, while instant vanilla pudding and sour cream add moisture, body, and a soft crumb that stays pleasant after cooling.
The cinnamon topping is divided into two layers, so every slice has more than just a little sugar on the surface. Brown sugar melts into a fragrant ribbon in the center, while the nuts toast gently on top for a pleasing contrast.
Easy preparation: The batter comes together in one large bowl.
Reliable texture: Pudding mix and sour cream help keep the cake moist.
Simple pan: A standard 9-by-13-inch baking dish makes generous, easy-to-serve squares.
Flexible topping: Use pecans or walnuts according to your preference.
It is also a practical recipe for sharing because the rectangular cake slices neatly and travels well once it has cooled. Serve it with coffee, tea, milk, or a spoonful of softly whipped cream for a relaxed dessert.
Ingredients You’ll Need
The main batter needs one box of yellow cake mix, about 15.25 ounces, plus one 3.4-ounce box of instant vanilla pudding mix. Choose a pudding mix labeled instant, since the recipe relies on its fine texture and does not require a separate cooking step.
You will also need four large eggs, three-quarters of a cup of vegetable oil, and one cup of sour cream. Full-fat sour cream is the best choice when you want the richest, most tender result, although plain Greek yogurt can be used as a substitute if needed.
For the topping, measure one-half cup of packed light brown sugar, one teaspoon of ground cinnamon, and one-half cup of chopped pecans or walnuts. Pack the brown sugar firmly into the measuring cup so the topping has the intended sweetness and texture.
Bring the eggs and sour cream to a cool room temperature if convenient for easier mixing.
Chop the nuts fairly small so they distribute well over both layers.
Grease the baking dish thoroughly, including the corners, to make serving easier.
How to Make It Step-by-Step
Step 1: Heat the oven to 350°F and grease a 9-by-13-inch baking dish. Preparing the pan before mixing means the thick batter can be transferred immediately, without sitting while the oven preheats.
Step 2: Combine the yellow cake mix and instant vanilla pudding mix in a large bowl. Stir the powders together first so the pudding is distributed evenly throughout the cake base.
Step 3: Add the four eggs, vegetable oil, and sour cream. Beat or stir until the batter is smooth and fully combined, but stop as soon as no dry pockets remain because overmixing can make the crumb less tender.
Step 4: In a separate bowl, combine the packed light brown sugar, ground cinnamon, and chopped pecans or walnuts. Stir until the cinnamon is spread through the sugar and the nuts are coated evenly.
Step 5: Pour half of the batter into the prepared pan and gently spread it into an even layer. The batter is thick, so use the back of a spoon or a small offset spatula and move slowly to avoid disturbing the pan coating.
Step 6: Sprinkle about half of the cinnamon-nut mixture over the first layer of batter. Keep the topping fairly even so the cinnamon ribbon reaches the edges and each future slice receives a little of the filling.
Step 7: Add the remaining batter and spread it carefully over the cinnamon layer. Finish with the remaining topping, distributing it from corner to corner for a crisp, fragrant top.
Step 8: Bake for 45–50 minutes, checking near the end of the baking window. The center should be set, and a toothpick inserted into the middle should come out with only a few moist crumbs rather than wet batter.
Step 9: Let the coffee cake cool for at least 15–20 minutes before slicing. This short rest allows the cinnamon layer to settle and helps the pieces hold together instead of becoming crumbly.
Pro Tips for the Best Texture
Because the batter is thick, gentle spreading is more effective than trying to pour it into a perfectly smooth layer. Drop spoonfuls across the pan first, then connect them with the back of a spoon or spatula.
Do not judge doneness by the color of the top alone. A golden surface can appear ready before the center has set, so test the middle with a toothpick and look for a few moist crumbs.
Full-fat sour cream contributes both richness and tenderness. Plain Greek yogurt works when that is what you have available, but the finished cake may be slightly less tender.
For the nut topping, pecans offer a buttery flavor, while walnuts bring a more pronounced earthy bite. Either choice works well, and the nuts should be chopped small enough to make clean slices rather than large, difficult-to-cut pieces.
Use a 9-by-13-inch baking dish for the stated baking time.
Keep the topping in two portions so the middle layer is not missed.
Let the cake rest before cutting for neater squares.
Use a serrated knife or thin chef’s knife and wipe it between slices if you want a tidy presentation.
Serving Suggestions
Serve the coffee cake slightly warm or at room temperature. Its cinnamon fragrance pairs naturally with freshly brewed coffee, black tea, chai, or a cold glass of milk.
For a brunch table, cut the cake into small squares and arrange them on a platter with the cinnamon-nut topping facing up. A dusting of powdered sugar is optional, but the cake is already sweet and flavorful without it.
This recipe also makes a comforting afternoon snack. If you want a more dessert-like plate, add a small spoonful of whipped cream or vanilla ice cream just before serving.
Storage and Reheating
Cool the cake completely before covering it so trapped steam does not make the topping soggy. Store it in an airtight container or cover the baking dish tightly.
Individual pieces can be served at room temperature, or warmed briefly until just soft and fragrant. Avoid overheating, since too much heat can dry the crumb and make the cinnamon sugar sticky.
For the best texture, slice only what you plan to serve and keep the remaining cake covered. The brief cooling period after baking is important, while continued protection from air helps preserve the moist interior.
Variations to Try
The core recipe is intentionally simple, but the topping can be adjusted without changing the cake method. Swap pecans for walnuts, or use whichever nut best suits your pantry and guests.
You can also make the cinnamon mixture slightly more rustic by leaving the nuts in varied sizes, though smaller pieces are best for neat slices. Keep the amounts of brown sugar, cinnamon, and nuts as written for the familiar balance of sweetness, spice, and crunch.
If using plain Greek yogurt in place of sour cream, stir it into the batter just as you would the sour cream and watch the cake closely during the final minutes of baking. The toothpick test remains the best guide to doneness.
Yellow Cake Mix Coffee Cake
A tender, moist coffee cake made with yellow cake mix, vanilla pudding, sour cream, and a cinnamon-pecan topping. This easy 9-by-13-inch cake is ready in about an hour.
Heat the oven to 350°F and grease a 9-by-13-inch baking dish. In a large bowl, combine the yellow cake mix and instant vanilla pudding mix.
Add the eggs, vegetable oil, and sour cream to the dry mixture. Beat or stir just until the batter is smooth and fully combined, taking care not to overmix.
In a separate bowl, stir together the packed brown sugar, ground cinnamon, and chopped pecans or walnuts. This mixture will create the sweet, warmly spiced ribbon and crunchy topping.
Pour half of the thick batter into the prepared baking dish and gently spread it into an even layer. Sprinkle about half of the cinnamon-nut mixture over the batter.
Add the remaining batter and spread it carefully over the cinnamon layer. Finish by sprinkling the remaining cinnamon-nut mixture evenly across the surface.
Bake for 45–50 minutes, or until the center is set and a toothpick inserted into the middle comes out with only a few moist crumbs. Cool the cake for at least 15–20 minutes before slicing.
Notes
Full-fat sour cream gives the moistest, richest texture. Plain Greek yogurt may be substituted, although the cake can be slightly less tender. Store cooled leftovers covered at room temperature for a short period or refrigerate for longer storage.
Final Thoughts
This Yellow Cake Mix Coffee Cake Recipe is an easy way to put a warm, homemade-style bake on the table in about an hour. The combination of yellow cake mix, vanilla pudding, eggs, oil, and sour cream creates a tender crumb, while the brown sugar, cinnamon, and pecans provide a delicious center stripe and crisp finish.
Remember to spread the thick batter gently, bake at 350°F for 45–50 minutes, and allow the cake to cool for at least 15–20 minutes before slicing. Those small details make the difference between a crumbly slice and a beautifully tender square.
Whether you serve it for a weekend breakfast, a casual brunch, or an afternoon coffee break, this dependable cake is easy to prepare and generous enough to share. Keep the recipe close for busy mornings when you want the aroma of cinnamon cake without a complicated baking project.
