A delightful twist on classic peanut butter cookie bars, these bars are layered with chocolate and drizzled with a creamy peanut butter glaze.
Preheat your oven to 350°F (175°C). Grease a 9x13 baking pan or line it with parchment paper.
Using parchment paper makes it easier to remove the bars from the pan after baking.
In a mixing bowl, beat the butter and peanut butter together until smooth and creamy.
Ensure the butter is at room temperature for easier mixing.
Add the granulated sugar and brown sugar to the butter mixture and beat until fluffy.
Scrape down the sides of the bowl to ensure even mixing.
Mix in the egg and vanilla extract until well combined.
Crack the egg into a separate bowl first to avoid shell pieces.
Gradually add the flour, baking soda, and salt, mixing until just combined.
Do not overmix to keep the bars tender.
Stir in the oats until evenly distributed.
Fold gently to maintain the texture of the oats.
Spread the batter evenly into the prepared baking pan.
Use a spatula to smooth the surface for even baking.
Bake in the preheated oven for 20 minutes or until golden brown.
Check for doneness by inserting a toothpick into the center; it should come out clean.
Sprinkle the chocolate chips over the hot base and let sit for 5 minutes.
The heat from the base will melt the chocolate chips.
Spread the melted chocolate evenly over the base.
Work quickly to spread the chocolate before it cools.
In a small saucepan, combine powdered sugar, peanut butter, and milk. Heat gently while stirring until smooth.
Adjust the milk quantity for desired consistency.
Drizzle the mixture over the chocolate layer and let cool completely.
Use a spoon or piping bag for a decorative drizzle.
Cut into bars and serve.
For cleaner cuts, chill the bars slightly before slicing.
