Step 1: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line them with parchment paper. This step is crucial for preventing sticking and ensuring easy release. A non-stick spray with flour also works wonders.
Step 2: In a large bowl, whisk together the all-purpose flour, granulated sugar, unsweetened cocoa powder, baking soda, and salt. Make sure there are no lumps, and everything is well combined.
Step 3: In a separate medium bowl, whisk together the vegetable oil, large eggs, and vanilla extract. Ensure the eggs are fully incorporated.
Step 4: In a third small bowl or measuring cup, combine the buttermilk, red gel food coloring, and white vinegar. The vinegar brightens the color and reacts with the baking soda later.
Step 5: Gradually add the wet ingredients (from Step 3) to the dry ingredients (from Step 2), mixing on low speed with an electric mixer until just combined. Do not overmix! Then, slowly pour in the buttermilk mixture (from Step 4) and mix until the batter is smooth and uniformly red. Scrape down the sides of the bowl to ensure everything is incorporated.
Step 6: Divide the batter evenly between the prepared cake pans. Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean. Baking times can vary, so keep an eye on them. Once baked, let the cakes cool in the pans for 10-15 minutes before inverting them onto a wire rack to cool completely. Cooling completely is essential before frosting!
Step 7: Prepare the Cream Cheese Frosting: In a large bowl, beat the softened cream cheese and unsalted butter with an electric mixer until light and fluffy. Gradually add the powdered sugar, one cup at a time, mixing until smooth. Stir in the vanilla extract. If the frosting is too thick, add a tiny splash of milk; if too thin, add a bit more powdered sugar. This classic frosting is what truly makes this easy classic red velvet cake recipe shine.
Step 8: Once the cake layers are completely cool, place one layer on your serving plate or cake stand. Spread a generous amount of cream cheese frosting evenly over the top. Carefully place the second cake layer on top and repeat with the remaining frosting, covering the top and sides of the cake. For a professional look, you can use an offset spatula to smooth the frosting. You can store any leftover cake in an airtight container to maintain its freshness. This easy classic red velvet cake recipe is best enjoyed when properly stored!
