What You’ll Need
For the Cake:
- 1¾ cups (210g) all-purpose flour – sifted for best results
- 1¼ cups (250g) granulated sugar
- ⅓ cup (75g) unsalted butter – room temperature
- 2 large eggs – room temperature
- ¾ cup (180ml) whole milk – room temperature
- 1½ teaspoons pure vanilla extract
- 1½ teaspoons baking powder
- ½ teaspoon salt
- 2 tablespoons vegetable oil – for extra moisture
Substitution Notes:
- Butter → All vegetable oil (½ cup total) for dairy-free option
- Whole milk → Buttermilk for tangier flavor and extra tenderness
- Granulated sugar → Brown sugar (1 cup packed) for richer flavor
- All-purpose flour → Cake flour (2 cups) for lighter texture
Step-by-Step Directions
- Preheat your oven to 350°F (175°C). Grease a 9×9-inch square baking pan with butter or cooking spray, then line with parchment paper, leaving overhang for easy removal. This ensures your cake comes out perfectly every time.
- Cream butter and sugar together in a large bowl using an electric mixer on medium speed for 2-3 minutes until light and fluffy. The mixture should look pale and increased in volume.
Pro Tip: Room temperature ingredients mix more easily and create a better texture. If your butter is too cold, cut it into small pieces and microwave for 10-15 seconds.
- Add eggs one at a time, beating well after each addition. Mix in vanilla extract and vegetable oil until fully combined. The oil helps keep your 9×9 cake extra moist.
- In a separate bowl, whisk together flour, baking powder, and salt. This ensures your leavening agent is evenly distributed throughout the cake.
- Alternate adding dry and wet ingredients to the creamed mixture. Begin with ⅓ of the flour mixture, mix briefly, add ½ of the milk, mix, add another ⅓ flour, mix, add remaining milk, mix, then final flour mixture. Mix just until combined—overmixing creates a tough cake.
- Pour batter into your prepared 9×9 pan and spread evenly with an offset spatula. Gently tap the pan on the counter 2-3 times to release air bubbles and ensure even baking.
- Bake for 32-38 minutes, or until the center springs back when lightly touched and a toothpick inserted in the center comes out with just a few moist crumbs. The edges should just start pulling away from the sides.
- Cool in the pan for 15 minutes, then use the parchment paper overhang to lift the cake out onto a wire rack. Cool completely before frosting to prevent melting and sliding.
Important: Square cakes can be trickier to remove than round ones, so don’t skip the parchment paper lining!

- Freezing: Wrap unfrosted cake in plastic wrap and foil, freeze up to 3 months
Flavor Variations:
- Chocolate version: Replace ¼ cup flour with cocoa powder
- Spice cake: Add 1 teaspoon cinnamon and ½ teaspoon nutmeg
- Citrus twist: Add 2 tablespoons lemon or orange zest
Frosting Tips:

- Glaze option: 1 cup powdered sugar + 2-3 tablespoons milk creates a simple drizzle
Common Questions
How is a 9×9 cake different from a round cake?
A 9×9 square cake has similar volume to a 9-inch round cake but bakes slightly differently due to the corners. The square shape provides more even heat distribution and creates neat, uniform portions that are perfect for serving at gatherings.
Can I double this recipe for a larger crowd?
Absolutely! Double the recipe and bake in a 9×13 pan, increasing the baking time to 35-42 minutes. This will serve 15-20 people and is perfect for larger gatherings or sheet cake needs.
What if I only have a round pan?
You can use a 9-inch round pan with this recipe—just reduce the baking time by 3-5 minutes and check for doneness around 30 minutes. The texture and flavor will be identical.
Why did my cake sink in the middle?
Common causes include opening the oven door too early, incorrect oven temperature, or expired baking powder. Make sure your baking powder is fresh (replace every 6 months) and avoid opening the oven until at least 25 minutes of baking time.
Can I make this cake mix ahead of time?
While it’s best to bake immediately after mixing, you can prepare the dry ingredients up to 2 days ahead. Store the flour mixture in an airtight container, then add wet ingredients when ready to bake.
How do I get perfectly even squares?
Use a ruler and mark your cutting lines with a knife tip before cutting. Clean your knife between cuts for the cleanest edges. For extra precision, chill the frosted cake for 30 minutes before cutting.
