Ingredients
Red Velvet Cake
- 270 grams cake flour (spooned and leveled)
- 300 grams granulated sugar
- 10 grams unsweetened cocoa powder (spooned and leveled, Dutch cocoa recommended)
- 1 tsp baking soda
- 1/2 tsp salt
- 113 grams salted butter (room temperature)
- 120 mL vegetable oil
- 3 large eggs (room temperature)
- 240 mL buttermilk (warmed)
- 2 tsp vanilla extract
- 2 tsp vinegar
- 6-8 drops red GEL food coloring
Ermine Buttercream
- 150 grams granulated sugar
- 30 grams all-purpose flour (spooned and leveled)
- 180 mL milk
- 263 grams unsalted butter (room temperature)
- 1 Tbsp vanilla bean paste (or vanilla extract)
- Pinch of salt
Instructions
- Make the Ermíne Buttercream Roux: In a small saucepan, whisk together sugar, flour, and salt until well combined. Gradually add milk while whisking to create a smooth mixture.
- Cook the Roux: Place the pan over medium heat and stir continuously but gently for 3-5 minutes until it begins to thicken and hold streaks. Then whisk briskly for another 30-60 seconds until it reaches custard-like thickness.
- Cool the Roux: Transfer the mixture to a heat-safe container, cover, and allow it to cool to room temperature, preparing the base for the buttercream.
- Prepare the Cake Pans and Oven: Preheat the oven to 350°F (177°C) convection. Grease and line four 6-inch cake pans with baking spray and parchment paper for easy release.
- Mix Dry Ingredients: In a medium bowl, whisk cake flour, cocoa powder, baking soda, salt, and sugar until evenly combined.
- Add Fats: Add vegetable oil and salted butter to the dry ingredients and beat until combined and smooth.
- Incorporate Eggs: Beat in eggs one at a time, mixing just a few seconds after each addition to incorporate without overmixing.
- Prepare Buttermilk Mixture: Warm the buttermilk and stir in vanilla extract, vinegar, and red gel food coloring until the color is fully dissolved.
- Combine Batter: Pour the buttermilk mixture into the batter and mix just until smooth and fully combined.
- Divide and Bake: Evenly distribute the batter into the four prepared cake pans (about 9 ounces each). Bake for approximately 25 minutes or until a springy center indicates doneness.
- Cool Cakes: Remove cakes from oven and invert onto a tea towel. Allow to cool completely to room temperature before frosting.
- Beat Butter for Frosting: Once the roux is cooled, place unsalted butter in a large bowl or stand mixer. Beat on high speed for 5 minutes until pale and fluffy, scraping the sides as needed.
- Incorporate Custard Roux: Gradually add the cooled roux in 3-4 increments to the butter while mixing at medium-high speed until smooth and well combined.
- Add Flavor and Finish: Mix in vanilla bean paste or extract and a pinch of salt until fully incorporated. Optionally, switch to a paddle attachment and mix on low for a few minutes to eliminate excess air for smooth piping.
- Assemble and Decorate: Use an offset spatula to frost the cooled cake layers generously. Decorate as desired, such as sprinkling with sparkling sugar for added elegance.
Notes
- Use room temperature ingredients for smoother batter and frosting.
- Warming the buttermilk helps dissolve the food coloring evenly throughout the batter.
- Do not overmix the batter after adding eggs to maintain cake tenderness.
- For best results, use Dutch-processed cocoa powder to achieve the classic red velvet flavor and color.
- The ermine buttercream is a cooked frosting that requires patience to achieve the right custard consistency but delivers a silky finish.
- Allow the roux to cool completely before adding to butter to prevent melting and separation.
- If you don’t have red gel coloring, use high-quality red liquid food coloring but gels provide more vibrant color with less impact on batter consistency.
