Instructions:
1. Preheat oven to 350°F (175°C). Grease a 13×18-inch sheet pan (or two 9×13 pans).

2. Make the bar batter:
In a large bowl, mix melted butter and peanut butter until smooth.
Add sugars, eggs, and vanilla; beat until combined.
Stir in flour, oats, baking soda, and salt. Mix just until incorporated.


3. Bake:
Spread batter evenly in prepared pan.
Bake for 18–22 minutes, or until golden brown and set. Do not overbake.
Let bars cool slightly while you prepare frosting.


4. Make frosting:
Beat butter and peanut butter until creamy.
Add milk, vanilla, and powdered sugar gradually until smooth and spreadable.
Adjust with a little more milk or powdered sugar if needed.


5. Frost bars:
Spread frosting evenly over warm (not hot) bars for a melt-in effect.
Allow to cool completely before cutting into squares.
