Ingredients

• 1 1/2 cups old-fashioned rolled oats
• 1 1/2 cups whole wheat flour
• 2 teaspoons baking soda
• 1 teaspoon baking powder
• 1/2 teaspoon salt
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon ground nutmeg
• 1 1/2 cups buttermilk
• 1 cup milk
• 1/3 cup white sugar
• 1/4 cup vegetable oil
• 1 egg
• 1/2 cup raisins
• 3 tablespoons chopped walnuts (optional)
• 1 teaspoon vegetable oil, or as needed

Instructions

1. Process oats in a food processor until finely ground. Mix oats, flour, baking soda, baking powder, salt, cinnamon, and nutmeg together in a bowl.
2. Whisk buttermilk, milk, sugar, 1/4 cup vegetable oil, and egg in a separate bowl until smooth; mix into oat mixture until batter is well-mixed, about 30 strokes. Fold raisins and walnuts into batter.
3. Lightly oil a skillet or griddle and place over medium heat. Drop batter by large spoonfuls onto the griddle and cook until bubbles form and the edges are dry, 3 to 4 minutes. Flip and cook until browned on the other side, 2 to 4 minutes. Repeat with remaining batter.
