These olive oil brownies are ultra fudgy, moist, and decadent! They have shiny crinkled tops, crisp edges, and soft gooey centers loaded with chocolate chunks.
Calling all chocolate lovers! You're going to love these rich, chocolatey olive oil brownies. Everyone needs a go-to brownie recipe, and this might be the one you make over and over again.
Olive oil may seem like a strange ingredient to bake with, but I love using it in cakes, olive oil cookies, and other baked goods. It has a delicious subtle fruity flavor that pairs incredibly well with chocolate. Using olive oil instead of butter makes it easy to make these brownies dairy free and helps them stay moist for days!
Why You'll Love This Recipe
- Ultra fudgy olive oil brownies- Making brownies with olive oil makes them super moist and soft. With bittersweet chocolate and cocoa powder, these chocolate bombs taste like eating fudge squares.
- Simple ingredients- You only need a handful of ingredients to make this recipe, most of which you might already have in your pantry. Olive oil is also full of healthy fats!
- Easy to make- I love sharing brownie recipes because they are so accessible and easy to make. Even beginner bakers will feel like pros after making these!
Here are some notes about the ingredients used. For quantities and full instructions, see the recipe card below.
- Chocolate- Use high quality bittersweet or dark chocolate for the best tasting brownies. I recommend brands like Guittard or Ghirardelli. Use chocolate chips or chopped chocolate bars.
- Olive oil- Any olive oil works since the flavor barely peeks through. If you want to be picky, use extra virgin olive oil that isn't too spicy, bitter, or peppery. I used Filippo Berio Extra Virgin Olive Oil and it had the perfect buttery, grassy flavor.
- Eggs- Large eggs bind the ingredients together. Make sure they are room temperature.
- Egg white- Since brownies are without leaveners (like baking powder and baking soda), using an egg white helps give them a little extra lift.
- Granulated sugar- This adds enough sweetness and retains moisture while letting the olive oil and chocolate flavors shine.
- Brown sugar- This adds more sweetness and moisture to the batter. You can use light or dark brown sugar, just make sure it's fresh and moist- not dried out.
- Vanilla extract- Vanilla enhances all of the other flavors.
- All purpose flour- This flour gives the best chewy, soft and fudgy texture. If you need these to be gluten free, use a cup-for-cup gluten free baking flour.
- Cocoa powder- Use dutch-processed cocoa powder. Dutch processed cocoa is treated with an alkalizing agent, which makes the cocoa less acidic and gives a deep flavor. You can use unsweetened regular (or natural) cocoa powder, but the chocolate flavor won't be as rich.
- Salt- Used to balance the sweetness and enhance the other flavors. Make sure your salt is finely ground. Add a ¼ teaspoon more if it is coarse.
- Chocolate: Semi-sweet or milk chocolate chips can be used instead of bittersweet or dark, but they'll make the brownies much sweeter. If you're preparing these for dairy free friends or family, use vegan chocolate.
- Granulated sugar: Coconut sugar can be substituted but may change the flavor slightly.
- Olive oil: If you're not an olive oil fan, use a different mild oil. Some examples are avocado, grapeseed, vegetable, and canola oil. I don't recommend coconut oil.
Helpful Equipment and Tools
- Mixing bowls- I love these heat-proof and dishwasher safe bowls. You'll need a medium bowl for melting the chocolate and a large bowl for mixing.
- Square baking pan- I like this one because it has flat, harsh edges. This makes it easy to clip parchment paper to the sides so you can easily lift the brownies out. You can use a glass or metal pan, but metal pans work the best for brownies. This is because metal heats up faster than glass, making the brownies rise and the edges crispy.
- Parchment paper- Precut parchment sheets make clean up so much easier!
Step by Step Instructions
Here are the steps to make the olive oil brownies. Before you start, preheat the oven to 350°F/180°C and line an 8x8 inch square baking pan with parchment paper.
STEP 1: First, melt 1 cup of chocolate in the microwave in a heatproof bowl. Mix every 15 seconds until completely melted and smooth. Then, whisk the olive oil in and let the mixture cool slightly.
STEP 2: In the bowl of a stand mixer with the paddle attachment or in a large bowl with a whisk or hand mixer, beat the eggs, egg white, white sugar, brown sugar, and vanilla extract together. Do this on medium-high speed for 2-3 minutes or until the color has lightened. If you whisk by hand, do it very vigorously for about 4 minutes.
STEP 3: While whisking, stream the chocolate oil mixture into the bowl. Continue mixing until homogenous.
STEP 4: Next, fold the flour, cocoa powder, and salt into the wet ingredients with a rubber spatula until no dry streaks of flour remain. Then, gently fold in the remaining chocolate.
STEP 5: Pour the brownie batter into the prepared baking pan. Spread the batter into an even layer with a rubber spatula or offset spatula and bake for 25-30 minutes or until a toothpick inserted in the center comes out with moist crumbs (a tiny bit of wet batter is ok too).
STEP 6: Remove the brownies from the oven and let them cool completely in their pan before cutting them into squares. Sprinkle with flaky salt and enjoy!
Expert Baking Tips
- Whisk the eggs and sugar vigorously! Did you know that a brownie's shiny, crinkled top is actually a thin layer of meringue made from eggs and sugar? Crazy, right! To get a crinkly top, beat the eggs and sugar rapidly so enough air gets incorporated.
- Sift the cocoa powder. Sifting the cocoa powder helps to remove any lumps and create a smooth batter.
- Don't overbake. It's ok if the center doesn't seem completely set when you take the brownies out of the oven since they'll continue baking as they cool. Overbaking results in tough, gummy brownies without gooey centers.
- Bake time may vary. Each oven is different, so the bake time may vary. After 25 minutes have passed, check on the brownies every 1-2 minutes for doneness.
Additions and Variations
Here are some ingredients you can add to brownies to make them extra special.
- Mix in chopped almonds, pecans, walnuts, or macadamia nuts.
- Swirl peanut butter, almond butter, cream cheese, or tahini on top the batter before baking.
- Frost with vanilla frosting, brown sugar buttercream, or cream cheese frosting when completely cool.
- Dust cocoa powder or powdered sugar on top.
Storage and Freezing
Olive oil brownies can be stored in an airtight container at room temperature for up to 5 days. I don't recommend refrigerating brownies since they can dry out. Reheat in the microwave for 10 seconds for a freshly baked feel.
Slice the brownies and place sheets of parchment or wax paper between each one so they don't stick together. Place in an airtight container or freezer bag and freeze for up to 3 months. When you're ready to enjoy, let them thaw on the counter for 3-4 hours.
