Preheat your oven to 350 degrees F. This step is crucial as it ensures your bars bake evenly. Take a moment to prepare your baking dish by greasing it lightly. An 8-inch square dish works perfectly for these bars.
In a large bowl, whisk together the dry ingredients: white whole-wheat flour, rolled oats, baking powder, and sea salt. Ensure everything is well mixed; this will help distribute the leavening agent evenly throughout the bars.
Next, mix in the melted coconut oil. You'll want to see a crumbly texture forming, which indicates that the dry ingredients are combining with the oil. This is an essential step for achieving the right consistency.
Spread half of the oat mixture into your prepared baking dish, about 2 cups worth. Use the back of a large spoon or your hands to press it down firmly. This base layer will hold the bars together and provide a delicious bottom crust.
Now it’s time to spread the raspberry jam carefully over the oat layer. This step requires a gentle touch; you don't want to disturb the base too much. Try to cover the entire surface evenly to ensure each bite is flavorful.
Sprinkle the remaining oat mixture over the jam. Again, press it down lightly with your hands or the back of the spoon to create an even layer. This will lock in the jam and provide some texture to the top.
Place the dish in your preheated oven and bake for about 35 minutes. Keep an eye on it as it bakes; you’re looking for a golden top that indicates the bars are cooked through.
Once baked, remove the dish from the oven and allow it to cool. This step is essential before cutting, as it helps the bars firm up and makes them easier to slice.
After cooling, cut the bars into squares. Enjoy them fresh or store them for later. I love to pack them for snacks on the go!
