Equipment
- Six 8-inch or 9-inch round cake pans (or bake in batches)
- Parchment paper for lining pans
- Mixing bowls
- Whisk and spatula
- Electric mixer (stand or hand mixer)
- Measuring cups and spoons
- Food scale (optional, for accuracy)
- Wire cooling racks
- Offset spatula for frosting
- Turntable (optional, for easy decorating)
Instructions
- Preheat & Prep: Preheat your oven to 350°F (175°C). Lightly grease six 8 or 9-inch round cake pans and line the bottoms with parchment paper for easy removal.
- Mix Wet Ingredients: In a large bowl, whisk together the unsweetened almond milk and apple cider vinegar. Let it sit for 5 minutes to curdle—this is your vegan “buttermilk.” Add the oil and vanilla extract, and mix well.
- Combine Dry Ingredients: In another bowl, sift together the flour, sugar, baking powder, baking soda, and salt.
- Make the Batter: Gradually add the dry ingredients to the wet mixture, whisking until just combined. Do not overmix—stop once you see no streaks of flour.
-
Divide & Color: Evenly divide the batter into six separate bowls (about 1 1/2 cups each). Add a few drops of food coloring to each bowl (red, orange, yellow, green, blue, purple) and gently mix until you reach your desired vibrancy.
Use gel food coloring for the brightest hues. Always check your colorings are vegan!
- Bake the Layers: Pour each colored batter into its own prepared pan. Bake for 16-20 minutes, or until the tops spring back lightly and a toothpick inserted in the center comes out clean. Rotate pans halfway if baking all at once.
- Cool Completely: Let the cakes cool in the pans for 10 minutes, then carefully turn out onto wire racks. Peel away parchment and allow to cool fully before frosting.
- Make the Vegan Buttercream: In a large bowl, beat the vegan butter until creamy. Gradually add the powdered sugar, 1 cup at a time, mixing on low. Add the plant milk, vanilla extract, and salt. Beat on medium-high until fluffy (about 3-5 minutes).
-
Assemble the Cake: Place the purple layer on a cake stand. Spread a thin, even layer of buttercream over the top. Repeat with blue, green, yellow, orange, and red layers, stacking as you go.
For an ultra-smooth finish, apply a “crumb coat” (thin layer of frosting), chill, then frost again.
- Decorate: Frost the outside of the cake with the remaining buttercream. Smooth the sides with an offset spatula. Add sprinkles, fruit, or more piping, if desired.
- Slice & Enjoy: Chill for 30 minutes for best slicing, then cut and serve your stunning vegan rainbow cake!
Tips & Variations
- Natural Dyes: Use beet, turmeric, matcha, spirulina, and blueberry powders for naturally colored layers.
- Make-Ahead: Bake cake layers a day ahead, wrap tightly and refrigerate or freeze. Frost the next day.
- Gluten-Free Option: Swap all-purpose flour for a 1:1 gluten-free blend.
- Frosting Flavors: Add lemon, almond, or coconut extract to the buttercream for a twist.
- Decorating Ideas: Try a naked cake look, top with vegan sprinkles, or add edible flowers.
- Don’t Overmix: For the fluffiest cake, mix until just combined.
- Other Plant Milks: Soy, oat, or rice milk all work well here.
