These chewy little squares can be made with whatever jam is in your pantry or strikes your fancy.

These delicious raspberry oatmeal squares are a snack, a dessert, even a breakfast treat. And while I love them with raspberry jam, whenever I find myself in possession of a new jar of preserves from a farm stand or given to me by a generous friend, I make these bars. The entire recipe comes together in just one pot, no extra bowls. How lovely.
You can use whatever jam you like instead of the raspberry. Try it with homemade strawberry jam! It’s a great make-ahead dessert. Store them at room temperature for a day or in the fridge for several days. They are also a nice offering at a bake sale.

Raspberry Oatmeal Bars are a simple make-ahead recipe that’s perfect for potlucks, bake sales, or just because…and it requires just one pot!
Ingredients for Raspberry Oatmeal Bars
- Unsalted butter – It’s always best to use unsalted butter when baking to control the level of salt in the finished product.
- Brown sugar – The brown sugar adds a deep, caramel-y flavor and moisture.
- All-purpose flour – You make an oatmeal-infused dough using the flour, which sandwiches the jam between two layers
- Baking soda – Helps the bars rise in the oven.
- Kosher salt – Balances out the sweetness in the recipe.
- Old-fashioned rolled oats – Add an amazing chewy texture.
- Jam – You can use raspberry jam, blueberry jam, or whatever fruit jam is your favorite. Just try to use seedless jam for the best texture.
How to Make Raspberry Oatmeal Bars
- Prepare to bake: Preheat the oven and butter or spray a baking pan with cooking spray.
- Make the dough: Melt the butter and then mix in the brown sugar, flour, baking soda, salt, and oats. It will be a crumbly, almost dry dough.
- Assemble: Press a little more than half of the dough into your baking pan. Push it in firmly so it is compact. Then spread the jam over the base. Crumble the remaining dough over the top loosely.
- Bake: Bake the bars for 40 to 50 minutes. Once you remove them from the oven, let them cool all the way before cutting and eating.
Make Ahead Oatmeal Raspberry Jam Bars
These bars are great to make ahead and bring to a bake sale or picnic. You can bake them up to a few days in advance and keep them in the fridge until you’re ready to eat them. You can also freeze the bars for a few weeks.

Ingredients
- 1 cup (2 sticks) unsalted butter
- 1 cup brown sugar
- 1 ½ cups all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon kosher salt
- 1 ½ cups old-fashioned rolled oats
- 1 (10- to 12-ounce) jar raspberry or blueberry or whatever jam (preferably seedless)
Instructions
- Preheat the oven to 350 F. Butter an 8-by-8–inch baking metal pan, or spray with nonstick cooking spray (if you use a glass pan, the cooking time will be a little longer).
- In a medium saucepan over medium heat, melt the butter. Remove from the heat, add the brown sugar, and stir until dissolved. Stir in the flour, baking soda, and salt, then blend in the oats; the mixture should be very crumbly.
- Measure 2 1/2 cups of the mixture (a little more than half) into the baking pan and press it firmly into the bottom so that it is evenly distributed. Spoon the jam over the top of the crumb base, using the back of the spoon to spread it evenly. Evenly distribute the reserved crumb topping over the top, pressing it lightly into the jam (it will just cover the filling).
- Bake for 40 to 50 minutes until lightly browned on top and firm. Cool completely in the pan on a wire rack. Cut into 16 squares.
Hi, would it work with a gluten-free alternative? I have almond, coconut and teff flours in my pantry. Also, would swapping the sugar with maple syrup ruin the consistency?
I haven’t tried it with another type of flour, but if you do, please let me know how it turns out!
Will do!
Oh, how I love a good bar cookie! These are always on the sweets table for any large party we have.
Thanks for the recipe. I made them the other day and my whole family loved them!
awesome!
Perhaps I’m biased but I swear to God these emails = best publicity/promotion I know of, for any book, from any publisher.
Yum!
Thank you Jennifer!
