Ingredients for 500 cake

Five simple ingredients create this bakery-style cake with layers light enough to float away.

The flour makes all the difference here. King Arthur or Gold Medal brands are my go-to—they're finely milled and give that signature tender crumb. The yogurt is non-negotiable for that signature moisture; Greek yogurt works best because it's thicker and adds protein for structure. Butter? Plugrá or Land O'Lakes unsalted melts beautifully without overpowering. I always measure my dry ingredients by scooping and leveling—no packing the flour! For the vanilla, Madagascar bourbon vanilla adds depth, but pure vanilla works too. The secret to that signature bakery texture is sifting the flour with the baking powder before mixing—it keeps everything light and airy.

No yogurt? Substitute with sour cream or applesauce—both add moisture, though yogurt gives the best texture. Running short on butter? Coconut oil works in a pinch, but it does have a slight coconut flavor. Want to skip the blueberries? Chopped chocolate or lemon curd swirls add gorgeous variation. The lemon zest might sound optional, but it's what makes this vanilla cake taste like it came from a patisserie—trust me on this. For the powdered sugar, Domino brand dissolves smoothly, but any quality brand works. If you're making this ahead, the batter can sit for up to 24 hours in the fridge for deeper flavor development.

This cake stays moist for 3-4 days when wrapped tightly in plastic. For longer storage, slice and freeze individual portions—they thaw in minutes and taste even better. I always bake mine in a 9-inch round pan for perfect layers, but an 8-inch pan works too if you're feeding fewer people. The blueberries (if using) should be tossed in a bit of flour to prevent sinking. And if you're feeling fancy, brush the warm cake with a simple syrup made from equal parts sugar and water—it keeps everything extra tender. Leftovers? Perfect for cake pops or French toast the next day!

Step-by-step instructions for light-as-air vanilla cake

Here's how to create a perfectly moist, fluffy cake with layers that feel lighter than air.

In a large mixing bowl, combine the 0.5 cup unsalted butter (room temperature) and the 0.5 cup granulated sugar. Using an electric mixer on medium speed, beat until the mixture is light and fluffy, about 3-4 minutes. You'll know it's ready when the mixture nearly doubles in volume and turns pale yellow. This step is crucial—it incorporates air that will create those airy layers.

I like to scrape down the sides of the bowl every minute or so to ensure everything gets fully incorporated. If your butter isn't quite room temperature, let it sit at room temperature for another 10 minutes before starting. Cold butter won't cream properly, leading to dense cake layers instead of light, fluffy ones.

Add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 0.5 cup plain yogurt and 1 tbsp vanilla extract. Mix on low speed just until combined—about 30 seconds. The yogurt adds moisture and tenderness, while the vanilla infuses that rich, comforting flavor we all love.

Here's the thing—don't overmix after adding the eggs. You want to maintain those air pockets we created earlier. If the mixture looks slightly curdled, that's normal. The flour will smooth everything out in the next step. Give it a quick taste at this point—you should detect that beautiful vanilla aroma.

In a separate bowl, whisk together the 1.5 cups all-purpose flour, 1.5 tsp baking powder, and 0.25 tsp salt. Sift the flour first for that perfect fluffy texture—this prevents lumps and ensures even distribution. Gradually add the dry mixture to the wet ingredients, mixing on low speed just until combined.

Here's where precision matters: Mix just until the flour disappears. Overmixing develops gluten, which makes cakes tough instead of tender. You should still see some flour streaks. Fold in the 0.5 cup fresh blueberries and 1 tbsp lemon zest by hand using a spatula. The blueberries add a lovely pop of color and juicy contrast, while the lemon zest brightens the whole flavor profile.

Preheat your oven to 350°F and grease two 6-inch round cake pans (or line them with parchment paper). Divide the batter evenly between the pans. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The cake should be golden on top but still slightly jiggly in the center—it continues cooking as it cools.

Don't open the oven door during baking! The sudden temperature change can cause the cakes to sink. When the timer goes off, let them cool in the pans for 10 minutes before transferring to a wire rack. This brief resting period prevents them from cracking as they cool completely. The result should be tender, moist layers with just the right amount of structure.

Once completely cooled, place one cake layer on a serving plate. Dust generously with 0.25 cup powdered sugar using a fine-mesh sieve. The powdered sugar adds that beautiful, elegant finish while keeping the cake light. Repeat with the second layer, then slice and serve.

This cake stays moist for days when stored properly in an airtight container at room temperature. The yogurt and butter combination creates that signature tender crumb, while the blueberries add just enough tartness to balance the sweetness. Each bite delivers that perfect combination of lightness and moisture we all crave in a cake!
