I first encountered these Strawberry Oatmeal Jam Bars when I was searching for a twist on a classic oatmeal cookie recipe. I couldn’t resist the idea of combining a crispy, buttery oatmeal base that calls for 1/2 cup unsalted butter, all-purpose flour, and rolled oats with a luscious layer of smooth strawberry jam.

It reminded me of those fun Oat Bars With Jam I used to eat when I was younger. The topping is equally temptin’ with unsalted butter, light brown sugar, one large egg and a splash of vanilla extract mixed together with more oats and flour.

The world of Strawberry Jam Squares and Easy Jam Bars have inspired me to recreate a simple yet irresistible dessert bar that doubles as a hearty breakfast. It might not be the healthiest option out there but it’s a delicious way to start your day or cap off a meal with a sweet treat.

Enjoy!

Third, the balance between the buttery base and the fruity topping is just perfect, giving me a treat that’s both a filling breakfast and a satisfying dessert. And lastly, I appreciate how versatile it is – sometimes I make it for a quick snack, other times as a special dessert for friends, and it never disappoints.

FAQ

Sure, you can swap out the strawberry jam for another flavor but keep in mind that the texture and sweetness of the jam will change how the bars taste.

Yeah, soften the butter until it's kinda creamy so it blends well with the other ingredients and gives you a smoother texture in the bars.

You can use margarine, but the flavor might change a bit. Butter gives a richer taste so if you can, it’s best to stick with it.

They’ll stay good for about 3 to 4 days in an airtight container at room temperature. If you need them to last longer, toss 'em in the fridge.

Yes, make sure you preheat the oven to 350°F so the base and topping cook evenly.

Strawberry Oatmeal Jam Bars Recipe Substitutions and Variations

  • Instead of unsalted butter, you can use margarine or even coconut oil if you dont mind a slight coconut flavor.
  • If you dont have all-purpose flour for the base or topping, try using whole wheat flour for a heartier texture or a gluten-free blend if that’s what you prefer.
  • You can swap rolled oats with quick oats if you want a softer bar, but be careful since the texture might be a bit different.
  • Instead of granulated sugar, you might want to use honey or maple syrup, though you’ll need to adjust the wet ingredients accordingly.
  • If you cant find smooth strawberry jam, you could try using strawberry preserves for a chunkier texture or even a homemade cooked strawberry compote.

Pro Tips

1. Always make sure your butter is softened to room temperature before you start, it really helps everything mix together better.
2. Try refrigerating the base for 10 minutes before adding the jam. That little step makes the crust a lot firmer and easier to handle.
3. Warm up the strawberry jam just a bit in the microwave so it spreads smooth and evenly over the base.
4. When beating your topping ingredients, do it until just combined. Overmixing can make the texture a bit tough, so it’s best to stop when everything is friendly with each other.
