Yes, you can use olive oil instead of butter in brownies. Olive oil makes brownies moist and fudgy, though it may slightly change the flavor and texture. Use a mild-flavored olive oil and replace butter in a 1:1 ratio. Keep in mind the brownies may be a bit denser and less rich than with butter, but they’ll still be delicious!

If you have ever typed “Can I use olive oil instead of butter in brownies?” you are in the right place. I have tested this swap in home ovens and pro kitchens. In this guide, I share clear steps, flavor picks, and science-backed tips so you can bake with confidence and get the exact texture you want.
The baking science behind swapping butter with olive oil
Here is what happens when you ask, Can I use olive oil instead of butter in brownies?, and then actually bake the batch. Butter has fat, water, and milk solids. Olive oil is pure fat. That simple change shifts texture, flavor, and crust.
What changes in your pan:
- Texture changes. Oil makes batter more tender because it coats flour well. Expect fudgier centers and a soft, moist crumb.
- Lift and crumb. You will get less lift because you cannot cream oil the same way as butter. That helps if you want dense brownies.
- Flavor notes. Butter brings dairy and caramel notes. Olive oil can add fruit, nut, or pepper hints. Choose the right one for your taste.
- Shiny crust. It is still possible. The sugar and egg method matters more than the fat type.
- Shelf life. Oil-based brownies stay soft longer because olive oil is liquid at room temp.
From a science view, this swap works because brownies rely on sugar, eggs, and chocolate for structure. Fat choice sets chew and moisture more than lift. My tests found that olive oil brownies hold well for three days without drying out. That is a nice bonus for make-ahead baking.

Choose the right olive oil for brownies
Before you decide, Can I use olive oil instead of butter in brownies?, match the oil to the brownie style you love. The oil flavor should play with cocoa and chocolate, not fight it.
Good picks:
- Extra virgin olive oil, mild. Great with dark cocoa. Look for notes of almond, apple, or light grass.
- Light or “pure” olive oil. Very neutral. Best when you want classic chocolate flavor to lead.
- Robust extra virgin olive oil. Use with caution. It can add pepper and a green edge. Works in dark, bittersweet styles with espresso.
Tasting tip:
- Smell the oil. If it smells fresh and a bit fruity, it will likely work in brownies.
- Taste a drop with a pinch of cocoa and sugar. If it tastes round and not bitter, it will bake well.
Pairing ideas:
- Orange zest, flaky salt, and mild extra virgin oil sweeten cocoa notes.
- Espresso, toasted nuts, and robust extra virgin oil make a bold bar.
How to substitute olive oil for butter the right way
So, Can I use olive oil instead of butter in brownies? Yes, and the ratio matters. Butter is about 80 to 82 percent fat. Olive oil is 100 percent fat. Use a bit less oil than butter.
Simple ratios:
- For every 1 cup of butter, use 3/4 to 7/8 cup olive oil.
- For 1 stick of butter (1/2 cup or 113 g), use about 6 tablespoons plus 2 teaspoons olive oil (about 93 g).
- If the recipe uses melted butter, start with 80 to 85 percent as much oil by volume.
Exact method I use:
- Whisk sugar and eggs until light and glossy. This helps the shiny crust.
- Stream in olive oil slowly while whisking. Make a smooth emulsion.
- Add warm melted chocolate or sifted cocoa next. Mix until smooth.
- Fold in flour, salt, and any leaveners just until combined.
- Rest the batter 5 to 10 minutes. This hydrates flour and thickens the mix.
- Bake at the same temp. Start checking 5 minutes early. Oil can speed set at the edges.
If you still wonder, Can I use olive oil instead of butter in brownies?, the short path is to swap at 80 to 85 percent and emulsify well.
Baker’s tweaks for a shiny crust:
- Use fine sugar and whisk it into eggs until most crystals dissolve.
- Warm the batter slightly with melted chocolate or a brief rest near a warm oven.
Will the brownies taste like olive oil?
If you use a mild extra virgin or light olive oil, the flavor will be subtle. With a robust oil, you will notice fruity or peppery notes, which can be great with dark cocoa.
Does olive oil make brownies cakey or fudgy?
It leans fudgy because oil keeps gluten relaxed and stays liquid at room temp. For cakier brownies, add one more egg white or a touch of baking powder.
Can I brown olive oil like brown butter?
No. Brown butter flavor comes from milk solids toasting. Olive oil has none, so there is no nutty browned note. Add toasted milk powder or malted milk if you want that vibe.
The Golden Rules for Substituting
| Conversion Rule | Tip |
| Use 3/4 the amount | If a recipe calls for 1 cup of butter, use 3/4 cup of olive oil. |
| Add liquid | Since you are removing the water content found in butter, consider adding a splash of milk or water (about 1/4 of the amount of butter replaced) to maintain moisture. |
| Choose your flavor | Extra Virgin Olive Oil (EVOO) adds a fruity, peppery complexity that pairs beautifully with dark chocolate. For a more neutral taste, use “Light” or “Refined” olive oil. |
| Consistency | If the recipe calls for creaming butter and sugar, mixing in oil will change the texture (making it denser). This works perfectly for fudgy brownies, but may not be ideal if you want a light, cakey brownie. |
Nutrition and dietary benefits and trade-offs
Many bakers ask, Can I use olive oil instead of butter in brownies? for health or diet reasons. Olive oil brings a different fat profile and removes dairy.
What changes with olive oil:
- Lower saturated fat per serving, higher monounsaturated fat.
- No cholesterol and no lactose. Helpful for dairy-free or kosher diets.
- Vitamin E and polyphenols remain in extra virgin oil, though heat reduces some.
Keep in mind:
- Brownies are still dessert. Sugar and chocolate set the calorie load.
- Use fresh oil. Rancid oil harms both flavor and nutrition.
Troubleshooting and pro tips from my kitchen
If you tried and thought, Can I use olive oil instead of butter in brownies? without losing that shiny crust, these fixes help. I learned them after many test pans.
Common issues and fixes:
- Too oily surface. You used too much oil. Drop the oil to 80 percent of the butter next time and whisk longer for a better emulsion.
- No shiny top. Warm your batter a bit and whisk sugar into eggs until thick and pale. A little melted chocolate helps.
- Bitter edge. Your oil may be too robust or old. Switch to a mild extra virgin or light olive oil.
- Crumb too dense. Whisk eggs and sugar longer. Add one tablespoon milk or coffee for more moisture balance.
- Edges overbaked. Drop oven temp by 10 degrees and line the pan. Start checking doneness earlier.
Pro tips:
- Add 1 teaspoon espresso powder to boost cocoa and balance olive notes.
- Finish with flaky salt. It brightens chocolate and rounds oil fruit notes.
- Rest the baked pan until just warm before slicing. Texture sets and cuts clean.
When to skip the swap
There are moments when the answer to Can I use olive oil instead of butter in brownies? should be no. Butter flavor is not always replaceable.
Skip olive oil when:
- You want brown butter notes. Olive oil cannot mimic toasted milk solids.
- You crave crisp, toffee-like edges. Butter browns and caramelizes more.
- You are baking a very light, airy brownie. Butter-based creaming helps lift.
Workarounds:
- Use half butter and half olive oil for balance.
- Add toasted milk powder for a browned note, if dairy is allowed.
- Add a touch of neutral oil with butter to keep edges crisp and center soft.
