Preheat the oven to 375°F (190°C) and line an 8"x8" (20cmx20cm) baking pan with parchment paper.
In a large bowl, mix together the rolled oats, flour, sugar, baking powder and salt.
1 1/2 cups (150 grams) rolled oats, 3/4 cup (94 grams) white whole wheat flour, 1/2 cup (100 grams) brown sugar, 1/4 teaspoon baking powder, 1/4 teaspoon salt
Cut in the coconut oil using a pastry blender, two knives or your fingers, and mix until the dough just comes together. The dough should not be very crumbly, but should stick together.
2/3 cup (149 grams) refined coconut oil
Gently press two thirds of it onto the bottom of the prepared baking pan.
Bake for 10-13 minutes or until the edges just start to brown.
Meanwhile, prepare the raspberry filling. In a medium bowl, mix together the raspberries, jam and vanilla. Lightly mash with a fork.
1 1/2 cups (180 grams) fresh or frozen raspberries, 5 tablespoons raspberry jam, 1/2 teaspoon vanilla
Spread this mixture over the baked crust and then sprinkle about 1/2 cup (90 grams) chocolate chips over the raspberry layer.
3/4 - 1 cup (135-180 grams) semi-sweet mini chocolate chips
Sprinkle the remaining oat mixture over the chocolate chips.
Bake for another 22-25 minutes or until the top has lightly browned and the filling is bubbly.
Remove from the oven and top with more chocolate chips, if desired.
Let the bars cool completely and then refrigerate for 2 hours before cutting.
Store any leftovers in the refrigerator for up to 4 days. These can also be frozen.
