Who says you have to choose between chocolate and vanilla? In our kitchen, these two classic flavors aren’t rivals—they’re the perfect power couple! This cake celebrates their beautiful harmony. We’re using a secret technique: infusing the batter with an entire minced vanilla bean, pod and all. This unlocks a deep, perfumy vanilla essence that provides a stunning backdrop for the rich, earthy notes of dark cocoa. The result is a show-stopping, incredibly moist, and tender two-layer cake that tastes as luxurious as it looks. Get ready to fall in love with chocolate and vanilla all over again!
Ingredients
• 1 whole vanilla bean, ends trimmed and finely minced
• 1/2 cup / 120 ml boiling water
• 1 cup / 120 g cake flour or all-purpose flour
• 3/4 cup / 75 g unsweetened cocoa powder
• 1 1/2 tsp / 6 g baking powder
• 1/2 tsp / 3 g salt
• 4 large eggs, at room temperature, separated
• 1 1/4 cups / 250 g granulated sugar
• 1/4 cup / 60 ml neutral oil, like grapeseed or corn
• 1 tsp / 5 ml vanilla extract
• For Assembly
• Your favorite frosting: Not-Too-Sweet Buttercream, Chocolate Buttercream, or Chocolate Ganache
• Optional: Raspberry jam for the filling
Instructions
1. Preheat your oven to 350°F / 175°C. Grease and flour two 8-inch or 9-inch round cake pans.
2. In a large bowl, place the finely minced vanilla bean and cover with the boiling water. Let it steep for at least 5-10 minutes while you gather the other .
3. In a separate medium bowl, whisk together the flour, cocoa powder, baking powder, and salt. Set aside.
4. In another clean, dry bowl, use an electric mixer to beat the egg whites on high speed until stiff peaks form. Be careful not to overbeat.
5. To the bowl with the steeped vanilla and water, add the egg yolks, sugar, oil, and vanilla extract. Beat with the electric mixer until the mixture is creamy, bubbly, and light in color.
6. Add the dry to the wet and mix on low speed until just combined and smooth. Do not overmix.
7. Gently fold the beaten egg whites into the chocolate batter in three additions using a spatula. Be thorough but gentle to maintain the airiness of the whites.
8. Divide the batter evenly between the two prepared cake pans. Bake for 20 to 25 minutes, or until a toothpick inserted into the center comes out clean.
9. Let the cakes cool in their pans for 10 minutes before carefully inverting them onto a wire rack to cool completely. Once cool, frost the first layer, add an optional jam filling, place the second layer on top, and frost the top and sides.

Pro Tips
• For the most intense vanilla flavor, mince the entire vanilla bean pod as finely as possible. If you’re hesitant, scrape the seeds out and add them to the batter along with an extra teaspoon of vanilla extract.
• Ensure your eggs are at room temperature. This helps the yolks blend more smoothly and allows the whites to whip up to their maximum volume, resulting in a lighter cake.
• When folding in the egg whites, use a light hand. The goal is to incorporate them without deflating the air you just whipped in. This is key to the cake’s tender crumb.
• Do not overbake. Check the cake at the 20-minute mark. A moist crumb is what you’re looking for, so pull it from the oven as soon as a toothpick comes out clean or with a few moist crumbs attached.
• For a fun twist, substitute the vanilla bean with 1/4 cup finely chopped cacao nibs, 2 teaspoons of fresh grated ginger, or 2 teaspoons of ground cinnamon.
