Use approximately
0.75 cup
of Canola oil
Notes
Rule of thumb
~3/4 cup oil per 1 cup butter
Accounts for water and milk solids in butter versus pure oil fat.
More butter by volume
~4/3 vs oil
Useful when a label lists liquid oil but you want to bake with butter.
Often
1:1 by volume
Swaps are easiest when flavor and smoke point are similar.
Many charts
1:1 with liquid oil
Creaming methods may differ—expect texture changes in cookies and pie dough.
Volume
Often 1:1 with oils
Extra virgin adds more flavor—great for dressings, selective for high heat.
Use sparingly
1:1 math, bold taste
Best as a finishing oil or in dishes where sesame belongs.
1 cup butter → canola oil (defaults in the calculator):
Substitute amount
0.75 cup
We convert your entered amount to milliliters, apply a volume ratio based on the fat type (for example butter to liquid oil), then convert back to your chosen unit. That keeps tablespoons, cups, and milliliters consistent in one pass.
Substitute volume ≈ recipe volume × ratioRatios are rules of thumb from common baking references—not exact chemistry for every cookie formula.
A 1:1 swap of refined oils can still fail in deep fryers if the substitute smokes at a lower temperature.
Laminated dough, delicate cakes, and recipes that depend on creaming solid fat with sugar may need more than a volume tweak—use trusted recipes or professional references for those cases.
Always melt and measure if the recipe expects liquid volume.
Vegetable oil ↔ grapeseed
Often 1:1 by volume
1 cup shortening → liquid oil
~1 cup (method-dependent)
