VEGAN OAT BARS

These vegan oat bars are a wholesome and delicious treat made with Just About Foods Oat Flour, fresh blueberries, maple syrup, and cornstarch. With a crumbly oat crust and a jammy blueberry filling, they're completely plant-based and perfect as a snack, dessert, or on-the-go breakfast.

How to Make Vegan Oat Bars

1- Preheat the oven: Heat the oven to 350°F (175°C) and lightly grease a tart pan or pie dish.

2- Make the crust dough: In a bowl, combine the oat flour, margarine (or coconut oil), maple syrup, and a pinch of salt. Mix until a crumbly dough forms.

3- Form the crust: Reserve half of the dough for the topping. Press the remaining half evenly into the bottom of the pan to form the crust.

4- Make the blueberry filling: In a saucepan, combine the frozen blueberries, maple syrup, lemon juice, and cornstarch. Cook over medium heat, stirring occasionally, until the mixture thickens and the berries soften, about 8–10 minutes.

5- Assemble the bars: Pour the blueberry filling over the oat crust and spread evenly. Crumble the reserved dough over the filling as the top layer.

6- Freeze: Place the assembled pan in the freezer for at least 30 minutes before baking.

7- Bake: Bake for 25–30 minutes, or until the crumble topping is golden and the filling is bubbling.

8- Cool and serve: Let cool completely before slicing. This helps the bars hold their shape when cut.

Tips for the Best Vegan Oat Bars

• Don't skip the freeze step — chilling the assembled bars before baking helps the crust hold its shape and prevents the filling from spreading.
• Use frozen blueberries straight from the freezer for the filling; they break down more evenly when cooked and release more juice.
• Press the bottom crust firmly and evenly to ensure a stable base that doesn't crumble when sliced.
• Let the bars cool completely at room temperature before cutting — slicing them warm will cause the filling to run.
• For cleaner cuts, refrigerate the cooled bars for 30 minutes before slicing with a sharp knife.

Variations

Mixed Berry Oat Bars Swap the blueberries for a mix of raspberries, blackberries, and strawberries for a colorful and tangy twist.

Peach Oat Bars Replace the blueberry filling with diced fresh or frozen peaches and a pinch of cinnamon for a warm, summery version.

Chocolate Oat Bars Drizzle melted dark chocolate over the cooled bars before serving for an indulgent finish.

FAQs

1. Why are my oat bars falling apart? The crust may not have been pressed firmly enough, or the bars were sliced before cooling completely. Press the dough firmly into the pan and wait until fully cooled — or refrigerate for 30 minutes — before cutting.

2. Why is my blueberry filling too runny? The cornstarch needs enough heat and time to activate. Make sure you cook the filling until it visibly thickens before pouring it over the crust. If it's still loose, add an extra ½ teaspoon of cornstarch and cook for 2 more minutes.

3. Can I use fresh blueberries instead of frozen? Yes. Fresh blueberries work well — the filling will be slightly less jammy but still delicious. Reduce the cooking time to 5–6 minutes since fresh berries soften faster.

4. Can I substitute coconut oil for margarine? Absolutely. Melted coconut oil works as a 1:1 swap and keeps the recipe fully vegan. The crust may be slightly more crumbly but will still hold together well.

5. Can I use honey instead of maple syrup? Honey works as a substitute but makes the recipe no longer vegan. Maple syrup is the recommended option for a fully plant-based bar.

6. How do I store these bars? Store in an airtight container in the fridge for up to 5 days. They can also be frozen individually wrapped for up to 2 months — thaw at room temperature for about 30 minutes before serving.

7. Can I make these gluten-free? Just About Foods Oat Flour is naturally gluten-free, but cross-contamination can vary by batch. Check the packaging and use certified gluten-free oat flour if needed.
