Notes
Make Ahead Instructions: The cake layers can be baked, cooled, and covered tightly at room temperature overnight. Likewise, the frosting can be prepared then covered and refrigerated overnight. Let the frosting sit at room temperature to slightly soften for 10 minutes before assembling and frosting.
Special Tools (affiliate links): 9-inch Round Cake Pans | Glass Mixing Bowls | Whisk | Electric Mixer (Handheld or Stand) | Red Gel Food Coloring or Beet Powder | Silicone Spatula | Cooling Rack | Cake Stand, Serving Plate, or Cake Turntable | Icing Spatula | Bench Scraper | Piping Bag (Reusable or Disposable) | Wilton Piping Tip #12 | Cake Carrier (for storing cake)
Cake Flour: For best texture and taste, I strongly recommend cake flour. You can find it in the baking aisle and I have many more recipes using it. If you can’t get your hands on cake flour, you can make a DIY cake flour substitute.
Vinegar: The vinegar helps brighten the red color. Don’t get scared, a touch of vinegar is normal in red velvet desserts! You can’t taste it.
Why is everything at room temperature? When everything is near the same temperature, they mix together easily, evenly, and produce a uniform texture. It’s important!
Food Coloring: The amount of red food coloring is up to you. I tested with varying amounts. To get the dark red color you see here, use 2 teaspoons of gel food coloring. You could use liquid food coloring too, but gel food coloring is more potent. You’ll need at least 1 Tablespoon of liquid. Dye the batter until you are pleased with the color. Use beet powder for a natural alternative (mix 1/2 teaspoon beet powder with 2 teaspoons of water before adding) or leave the food coloring out completely.
Buttermilk: Buttermilk is a key ingredient and flavor in this recipe. You can use low fat or full fat. If you don’t have buttermilk, you can make your own sour milk. To do so, add 1 and 1/2 teaspoons of fresh lemon juice or white vinegar to a liquid measuring cup. Add enough regular milk (whole milk is best) to make 1 cup. Stir the two together, then let it sit for 5 minutes before using.
Sheet Cake: This batter fits nicely into a 9×13-inch cake pan or 12×17-inch sheet pan. Same oven temperature. Bake for about 40-45 minutes or 20-25 minutes, respectively. Keep your eye on the cake and use a toothpick to test for doneness.
3 Layer Cake: Prepare 3 9-inch cake pans in step 1 and divide the batter evenly between the pans. Bake for about 22-25 minutes.
Bundt Cake: This cake batter fits into a 10-cup or larger bundt pan. I’m unsure of the exact bake time (likely around an hour), but use a toothpick to test for doneness. Same oven temperature.
Cupcakes: You can use this cake batter for 2-3 dozen cupcakes. Fill cupcake liners 1/2 – 2/3 of the way full. Bake for 20-21 minutes or until the tops of the cupcakes spring back when gently touched and a toothpick inserted in the center comes out clean. Use my red velvet cupcakes recipe if you need fewer.
