With jam being one of the easiest ways to preserve fruit in the summer, I always find myself with an abundance of jam. I used to have jam on my shelf for years because frankly my family isn’t a big “toast and jam” kind of family. This oatmeal jam bars recipe was a game-changer and a favorite recipe in my house. It’s a great way to use up different jams and it makes a delicious snack as well. You can also easily adjust the amount of sugar in this recipe depending on whether you want to make it as a healthy snack or a sweet dessert. 

What are Oatmeal Jam Bars?

Oatmeal jam bars are a type of dessert or snack that combines a crumbly, buttery oatmeal crust and topping with a sweet jam filling. They are typically made with simple ingredients and are easy to prepare.

Tips for Making Oatmeal Jam Bars

  • Jam: Use a high-quality jam or fruit preserve, preferably home-made! The better the jam, the more flavorful your bars will be.
  • Butter: Real, unsalted butter works best for a rich and buttery crust and topping.
  • Cutting: Use a sharp knife to cut the bars into squares or rectangles. For clean edges, wipe the knife with a damp cloth between cuts.

Ingredients you’ll need for this recipe:

  • 4 cups all-purpose flour
  • 2 cups quick or old-fashioned oats
  • 1-2 cup brown sugar or maple sugar (optional)
  • 1 tsp. Baking soda
  • 2 cups melted salted butter
  • 4 cups of any flavor jam or fruit sauce

How to Make Oatmeal Jam Bars

  1. Preheat oven to 350 F
  2. Mix dry ingredients: combine flour, oats, sugar, and baking soda until well blended.
  3. Stir in melted butter until the oat mixture is all moistened. 
  4. Remove and set aside 1 ½ cups of the oat mixture. Press the remaining mixture into the bottom of a parchment paper-lined jelly roll or half-sheet baking dish. Use the back of a measuring cup to firm up the mixture by pressing gently across the pan.
  5. Spread the jam over the oat mixture until the oat layer is fully covered in an even layer of jam.
  6. Sprinkle the 1 ½ cups of remaining oat mixture evenly across the top of the jam for a crumbly topping. 
  7. Bake for 45 minutes.
  8. Cool before cutting. For best results, I like to pop the whole pan into the refrigerator for a little bit to firm up the bars.

Pro Tip

Get creative! You can use jam, jelly, fruit sauce, applesauce, or pie filling. 

How to Store

Store the bars in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week.

Freezing: Allow the bars to cool completely. Cut into squares, and place them in an airtight container or freezer bag with parchment paper between layers to prevent sticking. They can be stored in the freezer for up to three months. When ready to enjoy, thaw them at room temperature or warm them slightly in the oven

    How do I know when the bars are done baking?

    The bars are done when the top is golden brown and the edges start to pull away from the sides of the pan. A toothpick inserted into the center should come out clean or with a few crumbs.

    1. Thank you for sharing this recipe! I have some peach jam to use up. My family doesn’t really do jam on toast. They don’t like peach jam with peanut butter for sandwiches either. I was kind of at a loss for what to do with all this jam. I cut the recipe in half to try out the recipe. I added 1/2 teaspoon of cinnamon to the crust that paired perfectly with the peach jam. They were delicious and everyone in the family loved them.
