Instructions

Simple birthday cake recipe – No fancy tools, no complicated steps—just straightforward baking that works

1. Prep your pans and oven. Heat oven to 350°F (175°C). Grease and line two 8-inch round cake pans (or one 9×13-inch pan) with parchment. Lightly flour the sides to prevent sticking.
2. Mix the dry ingredients. In a medium bowl, whisk flour, baking powder, baking soda, and salt. Set aside so it’s ready to go.
3. Combine the wet ingredients. In a large bowl, whisk sugar and eggs until slightly thick and pale, about 30–45 seconds. Whisk in melted butter, vanilla, milk, and sour cream until smooth.
4. Bring the batter together. Add the dry ingredients to the wet in two additions. Stir gently with a spatula just until you no longer see dry streaks. Do not overmix; a few small lumps are fine.
5. Fill and level. Divide batter evenly between the pans. Tap the pans lightly on the counter to release big air bubbles and level the tops.
6. Bake. Bake for 24–28 minutes for two 8-inch rounds, or 28–34 minutes for a 9×13-inch cake. The cakes are done when the centers spring back and a toothpick comes out with a few moist crumbs.
7. Cool completely. Let cakes cool in the pans for 10 minutes. Turn out onto a rack and cool fully before frosting. Warm cake will melt frosting.
8. Make the buttercream. Beat softened butter on medium speed until creamy and pale, 2–3 minutes. Gradually add powdered sugar, 1 cup at a time, mixing on low. Add vanilla, a pinch of salt, and 2 tbsp cream. Beat on medium-high for 1–2 minutes until fluffy, adding more cream or powdered sugar to reach a spreadable, smooth consistency.
9. Assemble. If needed, level the cake tops with a serrated knife. Place one layer on a plate, add a generous layer of frosting, and spread to the edges. Top with the second layer. Apply a thin crumb coat, chill for 10–15 minutes, then finish with a thicker coat of frosting.
10. Decorate. Add sprinkles, berries, or simple piping along the edges. Keep it easy and fun. Slice and enjoy.

Storage Instructions

• Room temperature: If your kitchen is cool, the frosted cake can sit at room temp for up to 1 day under a cake dome.
• Refrigerator: Store covered for 3–4 days. Bring slices to room temperature before serving for the best texture.
• Freezer: Wrap unfrosted layers tightly in plastic, then foil, and freeze up to 2 months. Thaw in the fridge overnight, then frost.
• Leftover frosting: Refrigerate up to 1 week or freeze up to 2 months. Stir or re-whip before using.

Why This is Good for You

It’s not a “health food,” but there’s value in a homemade celebration cake. You control the ingredients, sweetness, and portion size. There are no preservatives, and the flavors taste fresh and clean. Sharing a homemade cake also brings people together—there’s mental and social nourishment in that. If you want to lighten it up, use less frosting or pair slices with fresh fruit.

Pitfalls to Watch Out For

• Overmixing the batter: This can make the cake tough. Stir gently and stop when the flour disappears.
• Cold ingredients: Cold eggs or dairy can cause the batter to curdle or bake unevenly. Room temperature is key.
• Overbaking: Dry cake is often due to a few extra minutes in the oven. Start checking early, and look for moist crumbs on the tester.
• Too-stiff frosting: If the buttercream tears the cake, add a teaspoon of cream at a time and beat until smooth.
• Skipping the crumb coat: A quick thin layer locks in crumbs and gives you a clean final finish.

Variations You Can Try

• Confetti Cake: Fold 1/2 cup rainbow sprinkles into the batter just before baking. Use jimmies to avoid color bleeding.
• Chocolate Twist: Replace 1/3 cup flour with unsweetened cocoa powder and add 2 tbsp milk to the batter.
• Lemon Love: Add 1 tbsp lemon zest to the batter and 1–2 tbsp lemon juice to the frosting.
• Strawberry Filling: Spread a layer of strawberry jam between the cake layers, then frost as usual.
• Dairy-Free: Use plant-based butter, non-dairy milk, and dairy-free yogurt. Keep everything at room temperature.
• Gluten-Free: Use a 1:1 gluten-free all-purpose flour blend with xanthan gum. Mix gently and avoid overbaking.

FAQ

Can I make this cake ahead of time?

Yes. Bake the layers a day ahead, wrap tightly, and keep at room temperature or in the fridge. Frost the day you plan to serve. You can also freeze layers for up to 2 months.

What if I only have salted butter?

Use it, but reduce or omit the added salt in both cake and frosting. Taste the buttercream and adjust as needed.

How do I keep my cake moist?

Don’t overbake, measure flour correctly, and include the sour cream or yogurt for tenderness. Storing the cake covered also helps lock in moisture.

Can I bake this as cupcakes?

Yes. Line a 12-cup muffin tin and fill each about two-thirds full. Bake at 350°F (175°C) for 18–22 minutes. This recipe makes about 18–24 cupcakes, depending on size.

How do I get flat cake layers without domes?

Use baking strips around your pans or level the tops with a serrated knife once cooled. Avoid overfilling pans, which can cause doming.

What’s the best way to measure flour?

Use a scale if you have one. If not, fluff the flour, spoon it into the cup, and level it off. Scooping straight from the bag can pack in too much flour.

Can I color the frosting?

Yes. Use gel food coloring for bright, even color without thinning the frosting. Add a little at a time until you reach your desired shade.

Why did my frosting look grainy?

Powdered sugar may need to be sifted, or your butter was too cold. Beat longer and add a splash of cream. It should smooth out as it aerates.

Is vanilla extract or paste better?

Both work. Extract is simple and classic, while vanilla bean paste adds visible specks and a stronger flavor. Use what you have.

How do I transport the cake safely?

Chill the frosted cake for 30–45 minutes to set the frosting. Place it in a snug cake carrier and keep it on a flat surface in the car.
