Preheat oven to 375F.
In a medium to large bowl, combine all the dry ingredients.
In a smaller bowl, combine all the wet ingredients.
Then add the mixed wet ingredients into the dry ingredients and mix well.
Add the rolled oats, chopped walnuts and raisins into the mix.
Stir until just incorporated evenly.
Line a baking sheet with parchment paper.
Using two spoons, drop a heaping spoonful on the parchment-lined baking sheet.
Continue until the batter is dropped and the baking sheet is filled with raw cookies.
Bake at 375F for approximately 11 minutes or until done.
Let cool completely on the baking sheet. Store in an airtight container or resealable bag.
