Butter to Oil Conversion: Use ¾ cup (164g) Neutral vegetable oil (canola, corn, or vegetable)
To replace 1 cup unsalted butter, use ¾ cup (164g) Neutral vegetable oil (canola, corn, or vegetable) (best for carrot cakes, chocolate cakes, moist muffins, and quick breads). Swap solid butter for neutral vegetable oil or coconut oil in baking and sautéing with precise fat and moisture compensation.
Scaled Substitution Options
Vegetable Oil (3/4 Cup per Cup Butter)
Balance: Butter is ~80% fat and ~18% water, whereas vegetable oil is 100% fat. Use 3/4 to 7/8 cup oil per 1 cup butter.
Texture: Yields cakes that stay soft and moist for days even when chilled, as liquid oil remains fluid at cold temperatures.
Melted Virgin or Refined Coconut Oil
Balance: Use melted but cooled coconut oil so it does not prematurely melt other ingredients or curdle cold eggs.
Texture: Firms up when chilled similarly to butter, giving cookies crisp edges and soft centers.
Extra Virgin or Light Olive Oil
Balance: Reduce fat volume to 3/4 cup per cup of butter to balance total lipid percentage.
Texture: Produces an ultra-fine, velvety crumb with distinct fruity and herbal flavor notes.

Frequently Asked Questions
Why shouldn't I replace butter with oil 1:1 by volume? ▾
Butter is 16-18% water and 80-82% milkfat, while liquid oil is 100% pure fat; a 1:1 volume swap makes baked goods overly greasy and dense.
Can I cream oil with sugar like butter? ▾
No, liquid oils cannot trap air pockets with granulated sugar like plastic solid butter fat crystals do during creaming.
