Crispy Oat Crumble Bars with Jam

Fruity, crunchy, healthy oat bars – perfect for making ahead

Sometimes the best recipes come from a craving for something sweet without having to spend hours in the kitchen. That’s exactly how these crumble bars with jam came about.

They combine everything I love about simple baking recipes: a crunchy oat crust, a fruity filling, and golden crumble topping. That’s really all you need for a truly delicious snack.

I find it especially convenient that these bars are so easy to make ahead. They keep for several days in the fridge and taste fantastic even straight from the freezer.

Whether as an afternoon snack, with coffee, or as a sweet treat on the go, these fruity oatmeal bars are quick to make and always a good idea.

Why You’ll Love These Crumble Bars

There are recipes you try once and then forget about. And then there are recipes like this one. The ingredients are simple, they practically always turn out right, and you can reinvent the bars every time. Strawberries today, raspberries next week, and maybe apricots or blueberries the next time.

Plus, you don’t need any special baking skills. The crumble topping can be crumbly, the batter doesn’t have to look perfect, and in the end, it all tastes wonderful anyway.

Actually, these bars are the best proof that baking doesn’t have to be complicated.

Perfect for meal prep

If you like to cook or bake ahead, you’ll love this recipe. The bars keep well in the fridge for about five days and freeze beautifully. That’s why I usually bake a whole pan at once and freeze some of them. That way, I always have a small stash on hand for stressful days, unexpected guests, or those famous afternoon cravings for something sweet.

My personal favorite?

A slice taken from the freezer after being slightly thawed. The jam layer is still slightly firm and reminds you a little of a fruity ice cream dessert.

Which jam works best?

The great thing about this recipe is its versatility.

The bars taste especially delicious with:

• Strawberry Jam

• Raspberry Jam

• Apricot Jam

• Blueberry Jam

• Red Currant Jelly

For this recipe, I used a sugar-free strawberry fruit spread* from Vilgain and loved it right away. (Use my code “Annelina” to get 10% off at Vilgain.)

Longevity Tip

A longevity-friendly diet doesn’t mean giving up sweets. It’s much more important to regularly include foods that are filling, enjoyable, and easy to incorporate into your daily routine.

That’s exactly why I love these crumble bars so much. The combination of rolled oats, fruit filling, and healthy fats makes them much more filling than many traditional sweets. At the same time, they’re perfect for making ahead and help ensure you always have a homemade alternative on hand.

And sometimes, it’s precisely these small habits that make the biggest difference in the long run.

Ingredients

  

For the dough and the crumble topping:

• 150 g rolled oats
• 100 g oat flour
• 20 g tapioca starch
• 2 tsp cinnamon
• 1 pinch of salt
• 80 ml maple syrup or other syrup
• 40-50 ml olive oil or melted coconut oil
• optional: 1 to 2 tbsp chopped walnuts or pecans for extra crunch

For the filling:

• 250 to 300 g jam or fruit spread of your choice (I used a sugar-free strawberry spread from Vilgain)

Instructions

 

• Preheat the oven to 175 °C (top and bottom heat) and line a square baking pan (about 20 x 20 cm) with parchment paper.
• In a bowl, combine the rolled oats, oat flour, tapioca starch, cinnamon, and salt. Add the maple syrup and oil, and mix everything together until crumbly.
• Spread about two-thirds of the dough into the baking pan and press down firmly and evenly.
• Spread the jam over the bottom layer.
• Sprinkle the remaining dough over the top as a crumble topping.
• Optional: For extra crunch, you can add 1 to 2 tablespoons of chopped walnuts or pecans to the crumble topping.
• Bake for 25 to 30 minutes, until the surface is golden brown.
• Then let them cool completely before cutting into bars or squares.
• My little tip: Let the bars cool for at least 2 hours before cutting. This allows the jam layer to set, making the pieces much easier to cut neatly.

Notes

Raspberry, strawberry, or apricot jam works well for extra-fruity bars.
If you want to reduce the sweetness, you can use a fruit spread with no added sugar.
The bars will keep in the refrigerator for about 5 days and often taste even better the next day. I also freeze them so I always have some on hand, or to eat them half-frozen. They taste fantastic.
