Step 1: Preheat Your Oven - Start by preheating your oven to 350°F (175°C) for even baking.
Step 2: Prepare Your Baking Pan - Line a 9x13 inch baking pan with parchment paper, leaving overhang for easy removal.
Step 3: Mix Dry Ingredients - In a large mixing bowl, whisk together the flour, baking powder, salt, and malted milk powder until combined.
Step 4: Cream the Butter and Sugar - Beat the softened butter and dark brown sugar until light and fluffy, about 2-3 minutes.
Step 5: Add the Eggs and Vanilla - Add eggs one at a time, mixing well, then stir in vanilla extract until combined.
Step 6: Combine Wet and Dry Ingredients - Gradually add dry mixture to wet ingredients, stirring until just combined.
Step 7: Fold in the Good Stuff - Gently fold in the chopped malted milk balls and chocolate chips.
Step 8: Bake - Spread batter in the prepared pan and bake for 20-25 minutes until edges are golden brown.
Step 9: Cool and Slice - Let cool for 10 minutes in the pan before lifting out to cool completely on a wire rack.
