Ingredients:
2 cup white sugar
1 cup peanut butter
1 cup butter
½ cup water
2 tbsp. vanilla extract or to taste
2 large eggs
2 ¼ cups all-purpose flour
1 tsp. baking soda
½ tsp. salt or to taste
1 ½ cups rolled oats
1 ½ cups raisins
6 cups toasted whole grain oat cereal rings like Cheerios
Instructions:
Preheat the oven to 375 degrees F.
Mix sugar, peanut butter, butter, water, vanilla, and eggs together in a very large bowl until smooth.
Combine flour, baking soda, and salt; stir into cookie batter. Mix in oats and raisins, then carefully stir in cereal.
Drop 1/2 cupfuls of dough onto ungreased cookie sheets, spacing cookies about 4 inches apart. Flatten cookies to 1 inch thick.
Bake in the preheated oven until cookies are lightly browned at the edges, about 10 to 12 minutes. Let stand on the cookie sheets for 5 minutes before removing to wire racks to cool completely.
