Preheat oven to 350°F. Grease a 9 x 13 pan.
In a medium bowl, whisk together flour, rolled oats, malt powder, baking soda, and salt. Set aside.
In the bowl of an electric mixer, cream the butter, brown sugar, and sugar. Add peanut butter and mix until well combined.
Mix in eggs and vanilla extract until well combined, scraping down the sides of the bowl as needed.
Stir in the flour mixture, just until combined.
Spread the mixture evenly into the prepared pan and bake for 20 minutes, until baked through and beginning to brown around the edges. Allow to cool.
To make the glaze, stir together the powdered sugar, peanut butter, and milk until the mixture is a consistency that can be drizzled.
Spread the strawberry jam over the top of the baked bars. Sprinkle the crushed pretzels evenly over the strawberry jam.
Drizzle the peanut butter glaze over the top of the bars. Cut into 24 bars and serve.
