How to Make Jam Filled Oatmeal Bars
-
Preheat your oven to 350°F. Line an 8×8 inch pan with foil or parchment paper, then lightly spray with nonstick spray for easy removal later.
-
Mix the dry ingredients in a medium bowl: combine flour, oats, salt, and baking soda until well blended. This creates a solid foundation for your bars.
-
Whisk together the wet ingredients in a large bowl: melted butter, brown sugar, and vanilla until smooth. Now, add the dry mixture and stir gently until fully combined—this is where the magic begins!
-
Refrigerate about ¾ cup of the cookie dough for later. Press the remaining mixture into the prepared pan, creating an even layer across the bottom. Bake in the oven for 10 minutes to start the base off nicely.
-
Spread a generous layer of jam over the warm cookie base, making sure it reaches the edges for a burst of fruity goodness. Crumble the reserved dough over the jam, distributing it evenly.
-
Bake again for an additional 15-18 minutes until the topping is light golden brown and deliciously fragrant. Remove from the oven and allow to cool completely on a wire rack for the best texture.
Optional: Serve with a dusting of powdered sugar for a sweet presentation.

Expert Tips for Jam Filled Oatmeal Bars
-
Perfect Layering: Make sure to spread the jam evenly to prevent it from seeping out during baking. This way, each bite of your Jam Filled Oatmeal Bars is deliciously fruity.
-
Chill the Dough: Refrigerating the reserved dough helps it maintain shape and texture while crumbling. This key step gives your bars a lovely crumbly topping.
-
Check for Doneness: Ovens can vary, so keep an eye on your bars as they bake. Look for a light golden brown topping, as overbaking can lead to dryness.
-
Versatile Fillings: Don’t hesitate to experiment with different jams or preserves. Just remember to adjust sweetness based on the jam’s natural sugar content for the best results.
-
Cooling Time is Key: Let the bars cool completely on a wire rack. This allows the filling to set, preventing them from falling apart during slicing.

Jam Filled Oatmeal Bars Recipe FAQs
What kind of jam works best for these bars?
Absolutely! You can use any jam or preserve you love. Raspberry, apricot, and strawberry are wonderful choices! Just keep in mind that the sweetness of the jam might affect the overall flavor, so adjust the sugar in the recipe if you’re using a particularly sweet fruit spread.
How should I store leftover Jam Filled Oatmeal Bars?
You can keep your Jam Filled Oatmeal Bars in an airtight container at room temperature for up to 3 days. If you prefer them chilled, place them in the fridge, where they will last for up to a week! I often find that the jam flavor intensifies when chilled, making every bite even more delightful.
Can I freeze these bars for later enjoyment?
Yes, absolutely! To freeze, wrap each individual bar in plastic wrap, then place them in a freezer-safe bag. These bars can be stored in the freezer for up to 3 months. When you’re ready to enjoy one, simply thaw it in the refrigerator overnight or microwave it for 15-20 seconds for a quick treat.
What if my jam is too runny?
If your jam is on the runny side, don’t worry! To prevent the filling from leaking too much during baking, you can mix 1-2 tablespoons of cornstarch into the jam before spreading it on the base. This will help thicken it up and hold everything together nicely.
Can I use gluten-free flour instead of all-purpose flour?
Very much! You can substitute the all-purpose flour with a gluten-free blend. Just ensure it is a 1:1 baking mix designed for gluten-free baking. The texture may vary slightly, so be cautious of mixing too much, as gluten-free doughs can become dense quickly.
Is this recipe suitable for kids or those with allergies?
Absolutely! These bars can be a great treat for kids and anyone looking to enjoy a homemade snack. If you’re concerned about allergies, you can make them nut-free by ensuring the jam is also nut-free and using dairy-free butter if necessary. Always check the labels to be sure!
