Ingredients

  

• 1 box yellow cake mix (15.25 oz)
• 1/2 cup unsalted butter, melted and slightly cooled
• 3 large eggs plus 1 extra yolk
• 1 cup sour cream (full-fat for best texture)
• 1/3 cup milk (whole or 2%)
• 2 teaspoons pure vanilla extract
• 1/4 teaspoon fine salt
• Optional cinnamon-sugar topping: 1/4 cup granulated sugar + 1 teaspoon ground cinnamon
• Optional glaze: 1 cup powdered sugar, 2–3 tablespoons milk, 1/2 teaspoon vanilla
• Nonstick baking spray or butter for the pan

Instructions

 

• Prep the pan and oven: Heat oven to 350°F (175°C). Grease a 9x13-inch pan or a Bundt pan. Lightly flour if using butter.
• Combine the wet ingredients: In a large bowl, whisk melted butter, eggs, extra yolk, sour cream, milk, and vanilla until smooth.
• Add the dry mix: Sprinkle in the cake mix and salt. Stir with a spatula until just combined. Don’t overmix.
• Optional cinnamon layer: If using, pour half the batter into the pan. Mix cinnamon and sugar, sprinkle evenly, then add the rest of the batter.
• Bake: Bake 28–35 minutes for a 9x13, or 40–45 minutes for a Bundt, until the center springs back and a toothpick comes out clean.
• Cool: Let cool in the pan 10–15 minutes. For a Bundt, loosen edges and invert onto a rack. Cool completely if glazing.
• Glaze or dust: For glaze, whisk powdered sugar, milk, and vanilla until pourable. Drizzle over the cooled cake. Or dust with powdered sugar.
• Slice and serve: Cut into squares or slices. It’s great warm or at room temperature.

• Sour cream adds moisture and a tender crumb, so it tastes like a homemade butter cake.
• Melted butter beats oil for flavor, giving the cake a rich, golden taste.
• Extra egg yolk adds structure and color for that classic yellow cake vibe.
• Vanilla and a pinch of salt round out the flavors and balance the sweetness.
• A simple topping—either a cinnamon-sugar layer or a quick glaze—makes it feel special with minimal effort.

Health Benefits

• Portion control is easy: A small slice satisfies a sweet craving without going overboard.
• Dairy provides protein and calcium: Sour cream and milk add a little nutritional value and improve texture.
• Customizable sweetness: Skipping the glaze or using less sugar in toppings lowers the overall sugar load.

Common Mistakes to Avoid

• Overmixing the batter: This can make the cake tough. Stir just until the dry mix disappears.
• Using hot butter: Melted butter should be slightly cooled so it doesn’t scramble the eggs.
• Overbaking: Start checking early.A dry cake loses that homemade feel.
• Skipping salt: A tiny bit of salt enhances flavor and keeps it from tasting flat.
• Greasing a Bundt pan poorly: Thoroughly coat every nook to prevent sticking.

Variations You Can Try

• Lemon Bliss: Add 1 tablespoon lemon zest and swap vanilla for 1 teaspoon lemon extract. Top with lemon glaze.
• Chocolate Chip Snack Cake: Fold in 1 cup mini chocolate chips dusted with a teaspoon of flour.
• Apple Cinnamon: Stir in 1 cup finely diced apple and 1 teaspoon cinnamon. Great with the cinnamon-sugar layer.
• Almond Bakery-Style: Use 1 teaspoon almond extract and sprinkle sliced almonds on top before baking.
• Coconut Cream: Swap milk for coconut milk and fold in 3/4 cup shredded coconut.

FAQ

Can I use Greek yogurt instead of sour cream?

Yes.

Use full-fat Greek yogurt in the same amount. The texture stays moist, though the flavor is a touch tangier.

What if my cake mix is a different size?

If your box is between 15–16.5 oz, the recipe still works. For a larger box, add 1–2 tablespoons extra milk if the batter seems thick.

Can I make cupcakes?

Absolutely.

Fill lined muffin cups two-thirds full and bake 16–20 minutes. Check with a toothpick at 16 minutes.

How do I keep the cake from sticking to a Bundt pan?

Grease thoroughly with baking spray that contains flour, or brush on melted butter and dust with flour, getting into all the crevices.

Do I need a mixer?

No. A whisk and spatula work fine.

Mixing by hand helps prevent overmixing.

Can I reduce the sugar?

You can skip the glaze or use less. The base cake’s sweetness comes mostly from the mix, so adjust toppings first.
