Preheat the oven to 350 degrees and grease a 9x13 inch pan.
In a small bowl, combine the flour, baking powder, ginger, cinnamon, nutmeg, and salt.
In a large bowl, mix together the coconut oil, maple syrup, eggs, and vanilla. Stir in the flour mixture.
Add the oats, nuts, and raisins, and stir to combine evenly.
Press the dough evenly into the 9 x 13 inch pan. Bake for 25 to 30 minutes, until the edges are beginning to get brown.
Cool completely on a wire rack and cut into 14 bars. If you try to cut them before they’re cool, it’s likely that the bars will fall apart. Store them in an airtight container or freeze.
