Preheat oven to 350 degrees F. Line two cookie sheets with parchment paper.

Beat the butter until creamy. Beat in the brown sugar and granulated sugar. Cream mixture for about 5 minutes, then beat in the egg. Continue beating until light and fluffy, then reduce speed and beat in the oil, vanilla and malt powder (if using).

Mix together the flour, salt, cream of tartar and baking soda in separate bowl. Gradually add to egg mixture, stirring until incorporated, then stir in oatmeal, cereal, coconut, nuts and mini chocolate chips

Using a cookie scoop, scoop out fifty little balls of dough and arrange them on a foil lined cookie sheet so that you can chill the dough and bake as needed. PRESS THE BALLS DOWN BEFORE CHILLING. If you chill them as balls, the balls harden up and they crumble when you press them. Chill only if you don’t plan to bake them right away.

When ready to bake, space the little dough circles about 2 inches apart on baking sheets, and bake for 12 minutes at 350 F. or until lightly browned. Cool completely to get the proper texture. These cookies are NOT great warm.
