Why You'll Love This Recipe
About the Ingredients
2 cups (250g) all-purpose flour
Provides structure. For a lighter crumb, you can substitute 1 cup with cake flour, but all-purpose works beautifully.
1 1/2 cups (300g) granulated sugar
Sweetness and tenderness. If you prefer less sweet, reduce to 1 1/4 cups – the glaze will still balance it.
1/2 cup (113g) unsalted butter, softened
Adds richness. You can use salted butter and omit the added salt, but unsalted lets you control the flavor.
1/2 cup (120ml) vegetable oil
Keeps the cake moist. Use a neutral oil like canola or sunflower; olive oil will change the flavor.
3 large eggs, room temperature
Bind and leaven. Room-temperature eggs incorporate better – place them in warm water for 5 minutes if rushed.
1 cup (240ml) buttermilk, room temperature
Adds tang and tenderness. No buttermilk? Mix 1 cup milk with 1 tablespoon lemon juice and let sit 5 minutes.
2 teaspoons vanilla extract
Pure vanilla gives the best flavor. You can use vanilla bean paste or almond extract for a twist.
1/2 teaspoon almond extract
Subtle nuttiness that elevates the vanilla. Omit if you prefer pure vanilla, or increase to 1 teaspoon for more almond.
2 teaspoons baking powder
Leavening agent for rise. Ensure it’s fresh – test by stirring a bit into hot water; it should bubble vigorously.
1/2 teaspoon baking soda
Works with buttermilk for tenderness. Do not skip – it balances acidity.
1/2 teaspoon salt
Enhances flavors. Use fine sea salt for even distribution.
For the glaze: 2 cups (240g) powdered sugar, 3 tablespoons milk, 1/2 teaspoon vanilla extract
Creates a silky topping. Adjust milk to reach desired consistency – add a few drops at a time.
Tips & Tricks
- Use room-temperature ingredients for a smooth, evenly mixed batter – cold eggs or buttermilk can cause curdling.
- Don’t overmix the batter once flour is added; stir just until no streaks remain to keep the cake tender.
- Test doneness with a toothpick – it should come out with a few moist crumbs, not wet batter, around 35 minutes.
Pro Tips
Step-by-Step Instructions
1. Preheat and Prep
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan with butter or nonstick spray, then dust with flour, tapping out the excess. This ensures the cake releases cleanly.
2. Mix Wet Ingredients
In a large bowl, cream the softened butter and sugar together until light and fluffy, about 2-3 minutes. Add the oil, eggs, vanilla, and almond extract, mixing well after each addition. The mixture should look smooth and glossy.
3. Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. This distributes the leaveners evenly, ensuring a uniform rise.
4. Alternate Additions
Gradually add the dry ingredients to the wet mixture, alternating with the buttermilk, starting and ending with the dry. Mix on low speed or by hand until just combined – do not overmix, or the cake will be tough.
5. Pour and Smooth
Pour the batter into the prepared pan and use a spatula to spread it evenly to the edges. Tap the pan on the counter a few times to release any air bubbles.
6. Bake the Cake
Bake for 30-35 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs, and the top is golden brown. The edges will start to pull away from the pan. Ovens vary, so start checking at 30 minutes.
7. Cool in Pan
Remove the cake from the oven and place on a wire rack. Let it cool in the pan for 10 minutes – this allows the structure to set. Then, if you like, you can turn it out onto a serving platter or leave it in the pan for a rustic look.
8. Make Glaze
While the cake cools, whisk together the powdered sugar, milk, and vanilla in a small bowl until smooth. Adjust the consistency with a little more milk if needed – it should be pourable but not too thin.
9. Glaze and Serve
Pour the glaze evenly over the warm cake, spreading it gently with a spatula. Let it set for a few minutes before slicing. Serve warm or at room temperature, and enjoy every tender bite.
Delicious Variations
Lemon Blueberry
Replace almond extract with 1 tablespoon lemon zest and fold in 1 cup fresh blueberries before baking.
Chocolate Swirl
Melt 1/2 cup chocolate chips and swirl into the batter before baking for a marbled effect.
Spiced Apple
Add 1 teaspoon cinnamon and 1/2 teaspoon nutmeg, and fold in 1 cup diced apples tossed with 1 tablespoon flour.
How to Store 9 By 13 Cake
Refrigerator
Store in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days.
Freezer
Wrap the cooled, unglazed cake tightly in plastic wrap and foil; freeze for up to 3 months. Thaw overnight in the refrigerator before glazing.
Reheating
To refresh, microwave a slice for 10-15 seconds or warm in a 300°F (150°C) oven for 5 minutes.
Frequently Asked Questions
Q: Can I use a different pan size?
Yes, you can use two 9-inch round pans, but adjust baking time to 25-30 minutes. For a 9×13, the recipe is perfect as written.
Q: Why is my cake dry?
Overbaking is the most common cause. Check at 30 minutes and use the toothpick test – it should have a few moist crumbs, not be completely clean.

Yes, substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. Add 1/2 teaspoon xanthan gum if your blend doesn't include it.
Q: What can I use instead of buttermilk?
Make a quick substitute by adding 1 tablespoon of lemon juice or white vinegar to 1 cup of milk and letting it sit for 5 minutes.
Q: How do I know when the cake is done?
Insert a toothpick into the center – it should come out with a few moist crumbs, not wet batter. The edges will also pull away from the pan.
