Line a 8x8 square pan with aluminium foil with overhanging edges. Spray the aluminium foil with non-stick spray so that it's easy to peel off the bars once they have baked. Set aside.
Preheat oven to 350 F degrees.
In a bowl whisk together quick oats, all purpose flour, baking powder and salt.
Also add the brown sugar and 1/4 cup of M&M’s® Crispy. Mix everything together.
Add in the softened unsalted butter. Use a fork or your fingers to mix in the butter completely till there are no chunks.
Mix the butter till it's well incorporated with the mixture and the mixture looks like coarse crumbs.
Dump the mixture over the prepared baking pan, reserve 1/2 cup to add later on. Press it with your hands or using the back of your spoon till mixture is tightly packed.
Top the oatmeal layer with seedless raspberry jam. I microwaved the jam a little to make it easier to spread.
Now top the jam layer with the 1/2 cup of oatmeal mixture that we had set aside earlier.
Press the remaining 1/2 cup of M&M’s® Crispy on the top most layer.
Bake at 350 F degrees for around 30 minutes or till light golden brown from top.
Let the bars cool completely before cutting into pieces.
