These Healthy Strawberry Oatmeal Bars are a delicious treat that feels like a fresh bite of sunshine. Made with wholesome oats and sweet, tangy strawberries, they have just the right amount of chewy and soft textures that make snacking so satisfying. Plus, they are both vegan and gluten-free, so they work perfectly for lots of different diets.
I love keeping a batch of these bars in the fridge for quick breakfasts or an easy grab-and-go snack during busy days. What I really appreciate is that they don’t rely on any weird ingredients—it’s all simple, natural stuff that tastes great. Making them is also a little fun because you get to mix the oats with a fruit jam-like strawberry layer that turns out just right every time.
My favorite way to enjoy these bars is chilled, especially during warm weather. They feel so refreshing and filling without being too heavy. Whether you pack them in a lunchbox or enjoy them during an afternoon break, they always brighten my day a bit. And honestly, kids and adults both tend to love them, which is always a win in my book!
Key Ingredients & Substitutions
Gluten-Free Rolled Oats: Using certified gluten-free oats keeps these bars safe for gluten-sensitive eaters. Rolled oats give a chewy texture that’s perfect here. Quick oats can work but may become too soft.
Almond Flour: This adds moisture and a mild nutty flavor. If you have a nut allergy, try oat flour or a gluten-free all-purpose blend instead.
Coconut Sugar or Brown Sugar: Both sweeten naturally without refined sugar’s intensity. Maple syrup or agave are options but note they’ll add more liquid. Adjust the wet ingredients if swapping.
Coconut Oil: It binds ingredients well and adds a subtle richness. You can use melted vegan butter or any neutral oil like avocado oil, but coconut oil gives a nice firmness when chilled.
Strawberries: Fresh is best for brightness and texture, but frozen (thawed and drained) works too. You can mix in some blueberry or raspberry for variety.
How Do You Get the Perfect Strawberry Filling Without It Being Too Watery?
The secret is balancing moisture and thickening naturally:
- Chop fresh strawberries finely so they release juice evenly.
- Combine them with maple syrup and a little lemon juice—this boosts flavor and preserves freshness.
- Add chia seeds! These absorb excess liquid and create a jam-like texture after sitting for 10 minutes.
- Let the strawberry mix rest before spreading it on the base to thicken up.
- When baking, keep an eye on the edges so the filling doesn’t bubble over enough to make the base soggy.
Equipment You’ll Need
- 8×8-inch baking pan – great size for making bars that are easy to cut and share.
- Parchment paper – helps lift the bars from the pan for clean, simple removal.
- Mixing bowls – one for wet ingredients, one for dry; keeps things organized.
- Spoon or spatula – perfect for mixing and spreading the oat mixture and strawberry filling evenly.
- Measuring cups and spoons – to keep ingredient amounts accurate and your bars consistent.
Flavor Variations & Add-Ins
- Swap strawberries for blueberries or raspberries for a different fruity twist; these berries also release juice that works well in the filling.
- Add 1/4 cup chopped nuts like walnuts or pecans to the oat mixture for crunch and added healthy fats.
- Mix in a teaspoon of cinnamon or vanilla bean powder to the oat base for a cozy, warm flavor.
- Stir in some shredded coconut flakes into the oat mixture to boost texture and add a mild sweetness.
Healthy Strawberry Oatmeal Bars (Vegan + Gluten Free)
Ingredients You’ll Need:
For the Oat Base:
- 2 cups gluten-free rolled oats
- 1 cup almond flour (or other gluten-free flour)
- ½ cup coconut sugar or brown sugar
- ½ teaspoon baking powder
- ¼ teaspoon salt
- ½ cup coconut oil, melted
- 1 teaspoon vanilla extract
For the Strawberry Filling:

How Much Time Will You Need?
This recipe takes about 15 minutes to prepare and 30–35 minutes to bake. After baking, allow the bars to cool completely and then chill in the refrigerator for at least 1 hour to set, making the total time around 1 hour and 45 minutes.
Step-by-Step Instructions:
1. Prepare Your Baking Pan and Oven
Preheat your oven to 350°F (175°C). Line an 8×8-inch square baking pan with parchment paper, leaving some overhang on the sides to help lift the bars out easily later.
2. Make the Oat Base Mixture
In a large bowl, combine the gluten-free rolled oats, almond flour, coconut sugar, baking powder, and salt. Stir these dry ingredients together well. Add the melted coconut oil and vanilla extract, mixing until the mixture turns crumbly but sticks together when pressed.
3. Form the Base Layer
Press about two-thirds of the oat mixture evenly into the bottom of your prepared baking pan, making sure it’s compact and smooth. This will be the sturdy base for your bars.
4. Prepare the Strawberry Filling
In a separate bowl, mix the chopped strawberries with maple syrup, lemon juice, and chia seeds if using. Let this mixture sit for about 10 minutes to thicken naturally, which will help it hold together in the bars.
5. Assemble the Bars
Spread the strawberry filling evenly over the oat base. Then crumble the remaining oat mixture on top, gently pressing some crumbs into the filling but leaving others loose for a nice texture.
6. Bake and Cool
Bake the bars for 30 to 35 minutes, or until the top turns golden brown and the strawberry filling is bubbly. Let the bars cool completely on a wire rack.
7. Chill and Serve
Once cooled, refrigerate the bars for at least 1 hour to let them set fully. Use the parchment paper to lift them from the pan, then cut into squares. Enjoy chilled or at room temperature for a healthy, delicious snack or breakfast.
8. Storage
Store any leftover bars in an airtight container in the fridge for up to 5 days. They also freeze well for longer storage.
Can I Use Frozen Strawberries Instead of Fresh?
Yes, you can use frozen strawberries! Just thaw and drain any excess liquid before mixing them with the other filling ingredients to avoid a soggy base.
Can I Substitute Almond Flour?
Absolutely! You can use oat flour, gluten-free all-purpose flour, or any nut flour you prefer. Just keep in mind that different flours may slightly change the texture and flavor.
How Should I Store Leftover Bars?
Store leftovers in an airtight container in the refrigerator for up to 5 days. For longer storage, freeze the bars wrapped tightly to keep them fresh for up to 3 months.
Can I Make These Bars Nut-Free?
Yes! Simply replace the almond flour with oat flour or a gluten-free all-purpose flour to keep them nut-free while maintaining the texture.
