What You’ll Need
For the Cake:
- All-purpose flour – 1½ cups (190g)
- Granulated sugar – 1 cup (200g)
- Unsalted butter – ½ cup (113g), softened (or vegetable oil for extra moisture)
- Large eggs – 2, room temperature
- Vanilla extract – 2 teaspoons (pure vanilla recommended)
- Baking powder – 1½ teaspoons
- Salt – ½ teaspoon
- Whole milk – ⅔ cup (160ml) (or buttermilk for tang)
For Simple Buttercream (Optional):
- Unsalted butter – ½ cup, softened
- Powdered sugar – 2 cups
- Vanilla extract – 1 teaspoon
- Heavy cream or milk – 2-3 tablespoons
Substitution Notes:
- Dairy-free: Use plant-based milk and vegan butter
- Egg-free: Replace each egg with ¼ cup applesauce
- Gluten-free: Use 1:1 gluten-free flour blend
Step-by-Step Directions
1. Prep Your Pan and Oven
Preheat your oven to 350°F (175°C). Grease your 8-inch square baking pan with butter or cooking spray, then line with parchment paper, leaving some overhang for easy removal. Lightly flour the pan and tap out excess.
Pro tip: Room temperature ingredients mix more easily and create a smoother batter. Take your eggs and milk out 30 minutes before baking!
2. Mix the Dry Ingredients
In a medium bowl, whisk together flour, baking powder, and salt. This ensures even distribution and prevents pockets of leavening agent in your finished cake.
3. Cream Butter and Sugar
In a large mixing bowl, beat the softened butter and sugar together using an electric mixer on medium speed for 3-4 minutes until light and fluffy. The mixture should look pale and increase in volume—this creates the cake’s tender texture.
4. Add Eggs and Vanilla
Beat in eggs one at a time, mixing well after each addition. Add the vanilla extract and mix until combined. Don’t worry if the mixture looks slightly curdled—it will smooth out when you add the flour.
5. Alternate Wet and Dry Ingredients
Add one-third of the flour mixture to the butter mixture, mixing on low speed just until combined. Pour in half the milk, mix gently, then add another third of flour. Add remaining milk, mix, then finish with the last of the flour mixture.
Key technique: Stop mixing as soon as you don’t see dry flour. Overmixing develops gluten, making your cake tough instead of tender.
6. Pour and Bake
Transfer batter to your prepared pan and spread evenly with a spatula. Bake for 28-32 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs attached.
7. Cool Completely
Let the cake cool in the pan for 10 minutes, then use the parchment overhang to lift it out. Place on a wire rack to cool completely before frosting—about 1 hour.
How to Serve
This versatile cake pairs beautifully with:
- Fresh berries and whipped cream for a light dessert
- Classic chocolate or vanilla buttercream for celebrations
- A simple dusting of powdered sugar for casual occasions
- Ice cream and caramel sauce for an indulgent treat
Cutting tip: Use a sharp knife wiped clean between cuts for neat squares. This recipe yields 9 generous squares or 12 smaller pieces.
Expert Tips for Success
Storage: Wrap unfrosted cake in plastic wrap and store at room temperature for up to 3 days, or freeze for up to 3 months. Frosted cake keeps covered in the refrigerator for up to 5 days.
Flavor variations:
- Lemon cake: Add 2 tablespoons lemon zest and replace 2 tablespoons milk with lemon juice
- Chocolate cake: Replace ¼ cup flour with unsweetened cocoa powder
- Funfetti: Fold in ⅓ cup rainbow sprinkles before baking
Altitude adjustments: If baking above 3,000 feet, reduce baking powder to 1 teaspoon and increase liquid by 2-3 tablespoons.
Baker’s secret: Cake layers freeze beautifully! Wrap cooled, unfrosted cake tightly and freeze. Thaw completely before frosting—it’s actually easier to work with!
Common Questions
Can I double this recipe for a larger pan?
Yes! Double all ingredients and use a 9×13-inch pan. Increase baking time to 35-40 minutes. The cake will be slightly thinner but equally delicious.
What if I don’t have an electric mixer?
You can make this by hand! Cream the butter and sugar vigorously with a wooden spoon for about 5 minutes. The texture might be slightly denser, but it will still taste great.
My cake sank in the middle—what happened?
Usually this means the oven temperature was too high, causing rapid rising followed by collapse. Double-check your oven temperature with a thermometer, and avoid opening the oven door during the first 25 minutes of baking.
Can I make this cake ahead of time?
Absolutely! Unfrosted cake actually improves after a day as the flavors meld. Wrap tightly and store at room temperature. You can also make and freeze cake layers up to 3 months ahead.
How do I know when it’s perfectly done?
Look for edges that just start pulling away from the pan sides, a golden top, and a toothpick that comes out with a few moist crumbs. The cake should spring back lightly when touched in the center.
