In a large bowl combine flour, oats, brown sugar, baking powder, baking soda, salt, cinnamon, cloves, ginger, and ground nutmeg. Whisk quickly to combine and set aside.
To a medium mixing bowl add eggs, buttermilk, and vanilla extract. Add the butter in a stream and whisk until fully incorporated.
Add buttermilk mixture to the flour/spice mixture and fold with a spatula until combined and mostly smooth. Fold in raisins and allow the batter sit for a few minutes.
Heat griddle or pan over medium heat and lightly spray the griddle with cooking spray. Using a large cookie scoop pour batter by the scoopful onto the griddle. Cook pancakes on the first side until bubbles form on the surface and start to pop. Flip the pancake over with a spatula and cook until both sides are a nice golden brown. Repeat with remaining pancake batter.
Let cooked pancakes rest on a heat proof plate in an oven set to 200 degrees until ready to serve.
Makes about 15-20 pancakes
