Natural Blue Food Color Water Soluble

This moist Blue Velvet Layer Cake is an eye-catching twist on classic velvet cakes — light cocoa notes, tender crumb, and a vibrant natural blue color using Natural Blue Food Color — Water Soluble Extract. The cake batter is mixed simply (dry ingredients, wet ingredients, then color), baked in two 8-inch pans, cooled, then frosted with tangy cream-cheese buttercream. Use a few extra drops of the water-soluble extract to reach deep blue shades; gentle fold technique keeps the crumb tender and even. (Adapted and optimized from popular blue-velvet methods.)

Ingredients

    blank

    • 2⅔ cups (340 g) cake flour (or all-purpose + 2 tbsp cornstarch)

    • 2 tsp baking powder

    • ½ tsp baking soda

    • ½ tsp fine salt

    • 2 tbsp (12 g) unsweetened cocoa powder (gives classic velvet hint)

    • 1½ cups (300 g) granulated sugar

    • ¾ cup (170 g) unsalted butter, room temperature

    • 3 large eggs, room temperature

    • 1 cup (240 ml) buttermilk, room temperature

    • 2 tsp vanilla extract

    • 1 tbsp white vinegar (or 1 tbsp lemon juice)

    • Natural Blue Food Color — Water Soluble Extract — start with 20–30 drops

    • Optional: 1 tbsp vegetable oil (for extra moisture)

    blank

    • 8 oz (225 g) cream cheese, cold

    • ½ cup (115 g) unsalted butter, room temperature

    • 3–4 cups (360–480 g) powdered sugar, sifted (adjust to taste/consistency)

    • 1 tsp vanilla extract

    • Pinch of salt

    Directions

    1. Prep the oven & pans

      Preheat oven to 350°F (175°C). Grease and line two 8-inch cake pans; dust lightly with flour or use parchment rounds for easy release.

    2. Whisk dry ingredients

      In a medium bowl, sift (or whisk) together cake flour, cocoa powder, baking powder, baking soda, and salt. Set aside.

    3. Cream butter and sugar

      In a large bowl, cream the room-temperature butter and granulated sugar with a mixer on medium speed until light and fluffy (about 3–4 minutes). Scrape down sides.

    4. Add eggs & flavor

      Add eggs one at a time, mixing well after each. Mix in vanilla extract and optional oil.

    5. Alternate dry & buttermilk

      With mixer on low, add the dry ingredients in three additions alternating with buttermilk (dry → buttermilk → dry → buttermilk → dry). Mix just until combined — do not overmix.

    6. Add vinegar & natural blue extract

      Stir in the vinegar. Add Natural Blue Food Color — Water Soluble Extract in increments: start with 20–30 drops (about 1–1½ tsp) and stir to assess color; add additional drops 5 at a time for deeper blue. The color may deepen slightly while baking. (If using a liquid extract, remember it's water-soluble and will thin batter less than gel.)

    7. Bake

      Divide batter evenly between prepared pans. Smooth tops and bake at 350°F (175°C) for 25–30 minutes or until a toothpick inserted into the center comes out clean. Rotate pans halfway if your oven bakes unevenly.

    8. Cool completely

      Let cakes cool in pans 10 minutes, then remove to a wire rack to cool completely before frosting (avoid frosting warm cake to prevent melting).

    9. Make cream cheese buttercream

      With a mixer, beat cold cream cheese and room-temp butter until smooth. Gradually add sifted powdered sugar until you reach desired sweetness and pipeable consistency. Add vanilla and a pinch of salt; beat until silky.

    10. Assemble & decorate

      Level cake layers if needed. Place bottom layer on cake board, spread a thick, even layer of buttercream, top with second layer and crumb-coat. Chill 20–30 minutes, then apply final coat and smooth. Optionally decorate with blue sprinkles, edible pearls, or a lightly blue-tinted piping accent
