Ingredients for 5 cups flour cake

Five cups flour plus vanilla bean magic—this cake stays moist for days without gummy centers.

The flour is non-negotiable here—King Arthur or Gold Medal brands are my go-tos for consistent results. Room-temperature butter is key (stick it in the microwave for 40 seconds if it's cold), and vanilla bean extract makes all the difference. I always grab mine from Williams Sonoma or make my own by scraping seeds from pods. For the sugar, superfine dissolves faster, but regular granulated works if you pulse it in a food processor. The vanilla sugar is optional but adds that extra layer of flavor—worth it if you're making multiple cakes.

No vanilla bean extract? Pure vanilla extract at double the amount works in a pinch, but you'll miss that depth. Short on butter? Coconut oil or applesauce at half the quantity keeps things moist, though texture changes slightly. The milk can be swapped for buttermilk or almond milk, but whole milk gives the best crumb. Lemon zest is easy to skip, but it brightens the whole cake—zest a whole lemon and freeze the rest for future use. If you're baking at high altitude, reduce the baking powder by 1/4 tsp to prevent over-rising.

This cake keeps beautifully—3-4 days at room temperature wrapped in plastic, or 1 week in the fridge. For longer storage, freeze slices wrapped individually for up to 3 months. I like to bake two pans at once and freeze half for later. The vanilla flavor actually intensifies overnight, so leftovers taste even better. If you're nervous about drying out, brush slices with a little simple syrup before serving.

Step-by-step instructions for vanilla bean cake

Here's the method that guarantees a tender, moist crumb every single time.

In a stand mixer fitted with the paddle attachment, beat the 2 cups unsalted butter and 2 cups granulated sugar on medium speed for 3-4 minutes. You're looking for a pale, fluffy texture that nearly doubles in volume—this incorporates air that will create a light, airy crumb. I like to scrape down the sides every 30 seconds to ensure everything gets evenly incorporated.

The reason we wait until the butter is completely smooth is that any lumps will create dense pockets in your cake. Press the paddle against the mixture—when it leaves clean lines that hold their shape, you're ready for the next step. This usually takes about 3-4 minutes of continuous mixing.

Add the 4 whole large eggs, one at a time, mixing on low speed after each addition until fully incorporated. Then stir in the 1.5 cups whole milk, 2 tbsp pure vanilla bean extract, and 0.25 cup vegetable oil. The mixture should be smooth and slightly thick—almost like a thin batter. I always use room temperature ingredients because they blend more evenly and create a lighter texture.

Here's where the magic happens: the vanilla bean extract adds depth of flavor while the oil and milk ensure that signature moistness we're after. If your mixture looks curdled after adding the eggs, don't worry—it will smooth out once we incorporate the dry ingredients. The batter should be thick enough to leave a trail when you lift the paddle, but still pourable.

In a separate bowl, whisk together the 5 cups all-purpose flour, 2 tsp baking powder, 0.5 tsp salt, 1 tbsp cornstarch, 1 tbsp vanilla sugar, and 1 tbsp lemon zest. The cornstarch is key here—it helps retain moisture while the baking powder ensures a good rise. Sift the dry ingredients together to prevent clumping and create a light, airy mixture.

With the mixer on low speed, gradually add the dry ingredients to the wet mixture, mixing just until combined. I mean truly just combined—you should still see some flour streaks. Overmixing develops gluten and can make your cake tough. Stop mixing as soon as the flour disappears. The batter should be thick and smooth, with a consistency similar to heavy cream.

Preheat your oven to 350°F and grease three 8-inch round cake pans or line them with parchment paper. Divide the batter evenly among the pans and smooth the tops with a spatula. Bake for 25-30 minutes until a toothpick inserted in the center comes out clean. The edges should be golden brown while the center remains slightly springy to the touch.

I always check the cakes at the 25-minute mark because ovens vary. If the tops brown too quickly, tent them with foil to prevent overbrowning while the centers finish baking. The cake is done when it pulls away slightly from the edges of the pan and springs back when gently pressed in the center.

Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then transfer them to a wire rack to cool completely. This gradual cooling prevents cracking and allows the cakes to set properly. While they cool, I like to prepare my vanilla buttercream or whipped cream filling—this keeps everything ready for assembly.

For the ultimate moist texture, I recommend slicing the cooled cakes horizontally and layering them with your chosen filling. This creates a beautiful presentation while maintaining that signature tender crumb. The lemon zest in the batter adds a bright contrast that makes each bite sing with flavor.

Perfect pairings for this 5 cups flour cake

Classic Vanilla Frosting

This vanilla buttercream is my go-to for this cake—it’s rich, smooth, and complements the vanilla bean perfectly. Whip 1 cup unsalted butter with 4 cups powdered sugar, 2 tbsp heavy cream, and 1 tbsp pure vanilla extract until light and fluffy. For extra decadence, fold in ½ cup vanilla bean paste from Madison's Bakery or scrape seeds from a vanilla pod. Spread between cake layers and on top for a professional finish. 💛

Lemon Curd Filling

The lemon zest in the cake pairs beautifully with a tangy lemon curd filling. Make it by cooking ½ cup lemon juice, ½ cup sugar, and 3 egg yolks over low heat until thickened, then whisk in ½ cup butter. Let cool slightly before spreading between cake layers. The bright acidity cuts through the richness, balancing the vanilla notes perfectly. Serve with a dusting of powdered sugar for contrast.

Chocolate Ganache Drizzle

For chocolate lovers, a dark chocolate ganache adds a sophisticated touch. Heat 1 cup heavy cream until steaming, pour over 12 oz chopped dark chocolate, then let sit for 5 minutes before whisking smooth. Drizzle over cake layers or use as a glaze. The deep cocoa pairs surprisingly well with the vanilla, creating a complex flavor profile. Use Ghirardelli 70% dark chocolate for the best results.
