How to Make Oatmeal Fudge Bars (Vegan & Dairy-Free)
Step 1: Prep and Mix the Oatmeal Crumble
Start by preheating your oven to 350°F and lining an 8×8-inch baking pan with parchment paper for easy removal later. In a large bowl, cream together the softened dairy-free butter, brown sugar, and vanilla extract until light and fluffy—this step is key for that tender crumble texture. Then, fold in the flour, rolled oats, baking powder, and salt until everything is combined evenly. The oat crumble dough should hold together but be slightly crumbly, setting the stage for that marvelous textural contrast you’ll love.
Step 2: Press the Base Layer
Reserve about two-thirds of your oatmeal crumble dough and press it firmly into the bottom of your prepared pan. An even layer here means every bar you cut will have that perfect chewy and buttery base that holds the fudge topping beautifully. Don’t worry about getting it perfectly smooth—some rustic charm adds character!
Step 3: Make the Chocolate Fudge Layer
In a heatproof bowl, combine the chocolate chips and sweetened condensed oat milk. Microwave this mixture for 60 seconds, then stir in the vanilla extract. The heat from the oat milk melts the chocolate into a rich, silky fudge. Give it a good whisk until smooth and thickened, creating a luscious top layer that’s entirely dairy-free but indulgent beyond words.
Step 4: Assemble and Top
Pour the warm fudge over your oat crumble base, spreading it evenly so every bite gets that chocolate hit. Then take small clumps of the remaining oatmeal crumble dough and scatter them across the top, pressing down gently so they stick. This top layer adds a beautiful golden, crumbly finish that bakes up with irresistible texture and flavor.
Step 5: Bake and Chill
Bake your assembled bars for about 25 minutes or until the oatmeal crumble topping turns a lovely light golden brown. Let the bars cool completely at room temperature before popping them into the fridge to chill for at least an hour. This step firms up the fudge and makes slicing into neat, satisfying squares a breeze.
How to Serve Oatmeal Fudge Bars (Vegan & Dairy-Free)

Garnishes
Feel free to dress these bars up a bit with a sprinkle of flaky sea salt on top before baking to highlight the chocolate’s richness. For a fresh twist, garnish with a handful of toasted coconut flakes or chopped nuts, adding an extra dimension of texture and flavor that really pops against the fudgy interior.
Side Dishes
These bars are perfect on their own but can also shine when paired with a small bowl of fresh berries or a scoop of vegan vanilla ice cream. Serving them with plant-based whipped cream or a drizzle of almond butter can also elevate this treat into a more decadent dessert experience.
Creative Ways to Present
Cut these bars into smaller bite-sized squares for a party platter or individually wrap them to give as charming homemade gifts. You can also stack a couple on a dessert plate, dust with cocoa powder or powdered sugar, and serve with a warm cup of nut milk latte for a cozy afternoon snack that feels like a hug.
Make Ahead and Storage
Storing Leftovers
After chilling, store your Oatmeal Fudge Bars (Vegan & Dairy-Free) in an airtight container in the refrigerator. They keep wonderfully for 5 to 7 days and soften up nicely when left out at room temperature for 10 minutes before eating—perfect for enjoying a sweet treat anytime.
Freezing
If you want to keep these bars longer, wrap them tightly in plastic wrap or foil and freeze for up to 3 months. When ready to enjoy, thaw them in the refrigerator overnight to maintain that fudgy texture and chewy oatmeal goodness.
Reheating
To warm your bars slightly, pop them in the microwave for 15 to 20 seconds or enjoy them chilled straight from the fridge. This little step brings out the deep chocolate flavor and softens the crumble, making every bite melt in your mouth.
FAQs
Can I use gluten-free oats and flour to make these bars completely gluten-free?
Absolutely! Just swap in certified gluten-free rolled oats and a gluten-free all-purpose flour blend to keep the bars safe for gluten sensitivities without sacrificing texture.
What can I substitute for sweetened condensed oat milk?
You can replace sweetened condensed oat milk with sweetened condensed coconut milk or even make your own by simmering coconut milk and a sweetener until thickened. Both options create that creamy fudge layer needed for these bars.

Heating the sweetened condensed oat milk before mixing with chocolate chips is key to melting the chocolate smoothly and getting that rich fudge consistency. Be sure to stir well and let the fudge thicken a bit before spreading it over the base.
