1. Preheat oven to 350 degrees. Spray a 9×13 pan with non stick spray.

2. In a stand mixer, mix the butter and brown sugar for about 2 minutes on medium speed, until fluffy. Add the eggs, vanilla, salt, and baking powder and continue mixing until combined, scraping the sides of the bowl as necessary.

3. Add in flour, mix on low until just combined. Stir in the chopped apples and toffee bits. (taste the batter now. It’s incredible, right?)

4. Spread batter into the pan and bake for about 30 minutes until the center is set. Let cool completely, then frost.

Frosting Directions

1. Melt the butter in a medium saucepan. Add brown sugar and milk and bring to a boil. Remove from heat. Let cool for 5 minutes.

2. Stir in powdered sugar with a whisk and let cool until it thickens enough to spread.

Let frosting set for at least 30 minutes and then cut into bars.
