    Oat milk gives this healthy vegan chocolate sauce a natural creaminess with no added fat. It's silky smooth, made with 4 ingredients, and has a decadent hot fudge flavor you'll want to drizzle on everything! Contains no nuts, oil, dairy, gluten, or refined sugar.

    Truth? This chocolate sauce is blowing my mind. It is every bit as rich and delicious as it looks in the photos, yet it's made with just 4 wholesome ingredients. I honestly didn't know it was so easy to make such an epic and versatile chocolate syrup!

    This recipe comes to us courtesy of author Kim Lutz and her latest work The Oat Milk Cookbook. Big thanks to Kim and Sterling Publishing for allowing me to review the book and share a recipe with you.

    If you've visited my blog before you may be familiar with my obsession with oats, from this popular Vanilla-Maple Oat Ice Cream to blending oatmeal into pecan pie filling to using oat flour in baked goods like Banana Bread and Apple Cinnamon Scones. Oats are a total superstar in the vegan kitchen.

    The Oat Milk Cookbook highlights this as well. It features more than 100 delicious, dairy-free recipes that prove the versatility of oat milk for everything from cheesy sauces and soups to coffee drinks and desserts.

    I love that the first chapter includes information about the benefits of oat milk over dairy, such as the health, environmental, and animal cruelty issues. Kim also gives great tips about kitchen tools you'll need to make many of the recipes.

    I've already marked SO many pages throughout the book. Here are a few recipes I can't wait to try:

    • Frozen Pineapple Iced Tea
    • Holiday Spiced Coffee
    • Almond Butter Snack Cake
    • Pull-Apart Olive Oil Bread
    • Smoky Cheddar Drop Biscuits
    • Red Lentil Dip
    • Enchilada-Inspired Casserole
    • Cauliflower Oat Cream
    • S'mores Cookies

    And check out this gorgeous Oat Milk Sandwich Bread that Sarah of Bad to the Bowl made and shared.

    Making oat milk is as easy as: 1) blend, 2) strain. So affordable, too.

    See the Notes section of the recipe to learn how to make oat milk. Don't be intimidated! I promise it's easier than you might think.

    How to Make Vegan Chocolate Sauce

    The pure, simple genius of this chocolate sauce is why I chose it over all the other recipes in the book as the one I wanted to share. I mean, look at it! How can you not want to keep a jar of this heavenly sauce in the fridge at all times?!?! And when chilled it's like a fudge spread. This recipe has instantly become my go-to chocolate sauce.

    To make it all you need is a small saucepan, a whisk, about 10 minutes, and these 4 ingredients:

    • Cocoa powder
    • Vanilla extract
    • Maple syrup
    • Oat milk (see the Notes section of the recipe for instructions on making your own)

    Just stir everything together in the pan. Simmer for about 2 minutes, and you'll see the natural starch of the oat milk beginning to thicken and get ultra creamy. And that's it! 

    Serve the sauce warm or room temperature. And here's a little perk you might enjoy versus sauces that are made with added saturated fats.... this one doesn't harden as it cools. In fact, it's fantastic straight out of the fridge the next day! The consistency becomes more like a caramel sauce but with the flavor of deep, dark chocolate pudding. It's ridiculous.

    Also, feel free to add a pinch of salt to the pot. Next time I might try it with a bit of smoked sea salt.

    Serving Ideas

    Pair this healthy vegan chocolate sauce with:

    Oat Milk Ice cream
    Oat Flour Pancakes
    Cookies
    Healthy Brownies
    Oatmeal
    Biscotti
    Muffins
    Banana Bread
    Banana Nice Cream
    Slices of fresh apple, pear, or banana
    Chunks of frozen banana (yes, please!)
    And make hot chocolate and creamy vegan cocktails with it!

    During the week when you (or the kids) want a quick snack, pull the jar of sauce from the fridge and spread some on one half of a peanut butter-banana sandwich. #heaven

    Vegan Chocolate Sauce (Oil-Free; Oat Milk)

    Author: Lori Rasmussen, My Quiet Kitchen
    Oat milk gives this easy, 4-ingredient vegan chocolate sauce a natural, creamy thickness with no added fat. Silky smooth and ready in minutes, with a decadent, fudgey chocolate flavor. Contains no nuts, oil, dairy, or refined sugar.
    Reprinted with permission from Sterling Publishing Co; recipe by Kimberly Lutz, 2020.
    Yield: photos show a double batch, which makes about 1 ⅓ cups of sauce; as written here and in The Oat Milk Cookbook, the recipe makes about ⅔ cup sauce.
    Kim says she likes to double the recipe and keep a small jar in the refrigerator for up to a week. I completely agree.

    Notes

    How To Make Oat Milk

    1. Soak 1 cup rolled oats for about 30 minutes.
    2. After soaking the oats, drain and combine with 4 cups of water in a blender. In my Vitamix I like to blend on high for no more than 30 seconds to avoid overly slimy oat milk. Depending on your blender I recommend experimenting with this to find the perfect blend time. 
    3. Strain the oat milk through several layers of cheesecloth or a nut milk bag.
    4. Store oat milk in a lidded glass jar in the refrigerator for up to 3 days. Always shake oat milk before using.

    Storage

    Store leftover sauce in a lidded jar in the refrigerator for up to 1 week.
    I haven't tried freezing the chocolate sauce but have a feeling freezing it in ice cube tray could be a fun way to add quick chocolate flavor to smoothies or cocktails!

      Is there an alternative to the Maple Syrup? Trying to keep my sugar intake down.

        Hi Paul,
        I've only tested it with maple syrup, but I know there are some sugar-free syrup sweeteners out there made by companies like Lakanto. They have a monk fruit version of maple syrup that might work. If you give it a try let us know!

      This is very tasty. My family loved it. I used store bought oat milk ("Malk" brand, minimal ingredients). It took a lot longer than 2 minutes to thicken, maybe because it was cold, but it was worth the wait.

      This looks awesome- can’t wait to try it. Do you think this could be used in some way as a cake ‘frosting’ or as a layer in a layered chocolate cake? I’d love to know if you have any tips!

        Hi Jenessa, yes definitely. I actually have it on my to-do list to create a spreadable ganache from this recipe. 😀
        Once the sauce it chilled it thickens up nicely! You may need to experiment, depending on how you plan to use it. Maybe decrease the milk just a touch to make sure it's thick. One note though, since this is more of a liquid and frosting is solid (fat and sugar) I think it might soak into the cake over time. And you'd need to keep it chilled. I hope that helps!

      Do you think this could be made using canned coconut milk for a gluten free version?

        Hi Lacey, yes I think coconut milk will work well and I'm sure will taste fantastic, but you might need to whisk in a tiny amount of a GF starch like tapioca. Let us know if you try it!

      Is it possible to substitute another milk for the oat milk (since I only have rice milk on hand) or should I wait and buy oat milk? Thanks 🙂

        Hi Katherine, I have made it with other milks and while it still tasted great, the consistency was a little different. It’s the starch in oats that gives the extra creamy quality. If you happen to have old fashioned rolled oats on hand, making homemade oat milk as described in the Notes section is ideal!

          Hi Lori-can you buy the oat milk or does it change the consistency? Can't wait to try this one!

            Hi Sandi, absolutely, store-bought is fine. It will be slightly less stretchy/gooey (ha sorry, the best descriptors I can think of) only because of the way commercial oat milk is made, but still creamy and delicious.

      Can i store this at room temp?

        Hi Marquella, for freshness I recommend storing it in the refrigerator for up to a week, then briefly reheating it to make it pourable again. But because there aren't any highly perishable ingredients in this sauce I imagine it would be fine at room temperature for a short period. Difficult to say for sure, though.
