01 - Preheat the oven to 350°F. Line a 9x13-inch baking pan with parchment paper, leaving overhang for easy removal.
02 - In a large bowl, cream together butter, brown sugar, and granulated sugar until light and fluffy.
03 - Beat in eggs one at a time, then add vanilla extract.
04 - Whisk together flour, baking soda, and salt in a separate bowl. Gradually mix into the wet ingredients until just combined.
05 - Fold in chocolate chips and toasted sliced almonds.
06 - Spread the dough evenly into the prepared baking pan.
07 - Bake for 22–25 minutes, or until light golden and a toothpick inserted in the center comes out clean. Let cool completely in the pan.
08 - Beat the butter until creamy. Gradually add powdered sugar, milk, vanilla, and salt, beating until smooth and fluffy. Add more milk if needed for spreadable consistency.
09 - Spread frosting over the cooled bars. Sprinkle with toasted almonds and mini chocolate chips.
10 - Chill for 15 minutes to set the frosting. Lift out of the pan, cut into bars, and serve.
