Olive Oil Brownies (One Bowl, Dairy Free)

These olive oil brownies are dense and chocolatey with crisp edges, sweet chocolate chips and a crackly top. Everything a brownie should be. You’ll only need a whisk and a bowl to make them too – no mixer required. And, did I mention they’re dairy free?

A few weeks ago, I asked one of my dairy free recipe groups on Facebook what sort of recipe they’d like to see. One of the first comments was brownies, and I was surprised I hadn’t thought of it before. Who doesn’t love a good brownie? And, I knew that before long, I’d be making batches and batches of brownies because I knew that brownies would be an easy recipe to convert to dairy free.

In fact, I know that there are at least two major brands of brownie mix that don’t contain any milk products. So I figured it would be a breeze to replicate with real food ingredients. Unfortunately, it ended up being harder that I thought to find a good base recipe to convert. So many recipes out there only make a 8×8 square pan of brownies. And, if you’re anything like me, that’s no good. If I’m going to spend time making brownies, I want a decent sized batch. A 9×13 pan of olive oil brownies was a must for me.

How to make olive oil brownies:

I found this recipe for old fashioned brownies on Pinterest, and I thought it would be a great starting point for my dairy free brownies. It used melted butter, which is easily substituted with oil, and cocoa powder rather than melted chocolate or anything too complicated for me. The only other change I made was to double the vanilla extract. It’s a trick I learned after my niece accidentally used tablespoons instead of teaspoons in her chocolate chip cookies, and they turned out amazing.

And, these brownies were no different. They turned out better than any brownie I’ve ever had in my whole life. Try them for yourself and let me know what you think.

Tips for making dairy free, olive oil brownies:

  • Use any olive oil you have on hand. I used extra virgin, but a lighter olive oil would work, too.
  • Take them out of the oven before you think you should. If you’re toothpick comes out with a tiny bit of batter on it, that’s okay. They’ll be nice and fudge-link.
  • Use the best dairy free chocolate chips you can find. I found a local brand that makes dairy free ones, but Enjoy Life makes allergy friendly chocolate chunks that would work great.
  • Line your baking dish with parchment paper *affiliate link. Just fold the corners. It doesn’t have to be perfect because the batter will fill it out.

    7 Dairy Free Substitutes for Butter - Simply Whisked
    March 13, 2018 at 8:03 pm

    […] Extra virgin olive oil is always my first choice in dairy free substitutes for butter in a recipe. I use it in all my savory recipes, and it’s especially good when a recipe calls for you to melt butter in a pan (like when you’re sautéing onions). I use it when I’m making risotto and my favorite brownies. […]

    I cooked my brownie in a smaller pan 7″ x 10 1/2″ ( 18 cm x 27 cm ) and it turned out perfect.
    Also try putting extra choco chips on top after baking it to melt for a great topping.

    Excellent Brownie Recipe. I also baked this in a smaller pan and in addition to the cocoa, I added 2 teaspoons of Instant Coffee to enhance the chocolate flavor.

    This is my first time attempting dairy-free brownies and to be honest, these are so good that no one will miss the butter-filled version! I did make a couple of alterations based on the reviews and my own experiences in the kitchen.
    1. Smaller pan – I used 10 X 7ish (baked for 35 minutes on 350*). So moist!
    2. Added espresso powder – a must when making chocolate cake or brownies in my house
    3. Increased the vanilla to 1 TBSP

    Thanks for the recipe! It’s a keeper!

      Thanks for sharing! I love that you added extra vanilla. It’s one of my favorite ways to amp up the flavor, but I try not to suggest it in my recipes because it can be so expensive. I’m glad you liked these!

    Incredibly fudgy and decadent. I used dark chocolate and just cut it up. Also used smaller pan as that’s all I had. Really nice brownie recipe.

    This is SO GOOD.

    Like another reviewer, I didn’t have chocolate chips so I chopped up a couple dairy-free dark chocolate bars. It ended up they didn’t hold their shape like chocolate chips, but they created little areas of melty deliciousness.

    A couple other reviewers mentioned using espresso powder. This sounded like a great idea but I didn’t have any, I I substituted the 1/2 of boiling water with hot, dark decaf coffee. Also increased the vanilla to one tablespoon.

    Seriously, you wouldn’t know these are dairy free — so fudgy and flavorful — and they’re actually better than just about any dairy-full brownies I’ve made. (Rocky Road was my family’s go-to in my dairy-full days…your recipe could probably easily be modified to include the nuts and marshmallows!)

    Thanks so much for the recipe!

    Not bad. I didn’t have semisweet dairy free chocolate chips, so I used dark chocolate instead. I cooked them in smaller pans, and they turned out well. The corner pieces are a bit dry, but it’s very rich and fudgelike towards the middle. It’s definitely a keeper.

    Thanks for this yummy recipe! Question though: I followed the recipe exactly, but mine looks nothing like yours. It came out more like a cake. Yummy, but cake not brownie. What am I doing wrong?? I never seem to make brownies, they always come out like a cake. Could it be my oven, or do I just not have the brownie thumb? Any ideas?

      It might just be that you’re baking them too long or your oven is too hot. You really want to take them out earlier than you *think* they’re ready. If that doesn’t work, try replacing half 1 cup brown sugar and 1 cup sugar (rather than 2 cups of sugar).

    The taste is great on these! Unfortunately 35 minutes was way too long for mine – they were burning several minutes before my timer went off and they came out tasting more like a slightly burnt cake than brownies 🙁 Would recommend checking these 25 minutes in just to be sure, or maybe using a smaller pan would do the trick!

    I also think 2 c of sugar would have been too much – I used only 1.5 and they still came out plenty sweet.

      The sugar does more for the recipe than just sweetening. It actually gives the brownies their gooey texture. Since you changed the ingredients, you can’t expect the recipe to come out properly. Oven temperatures also vary quite a bit, so you should always keep an eye on what you’re baking and get to know your own oven. I’m glad they still turned out ok!

    Absolutely excellent recipe and I work in the Congo with no suitable oven, and they still came out perfect!

    The outside has the perfect amount of stretchy crispness and the inside is dense without being too heavy. This is a new favorite!

    I’ve been dairy-free my whole life by necessity, and finding tasty desserts has always been a challenge! Loved this recipe, thank you so much! I will say that I substituted some applesauce in for some of the olive oil as another reviewer brought up that idea, and though the brownies have a wonderful texture, they are less chocolate-y tasting. I used unsweetened organic applesauce, and the brownies are almost a fruity-sweet taste, similar to carob-powder brownies. Since I prefer a VERY strong chocolate taste, I’ll probably add more cocoa powder but keep the applesauce in the future! (I can’t have caffeine, so sadly I couldn’t add coffee or espresso to enhance the chocolate as others have suggested!)
