Step 1

Preheat the oven to 325 degrees F. Spray a 13×9 inch glass pan with baking spray.

Step 2

Peel and chop the apples into about 1/2 inch cubes. Set aside.

Step 3

In a large mixing bowl, add the softened butter, oil, sugars, eggs and extract. Whisk well.

Step 4

Add in the dry ingredients (not the apples yet) to the liquid ingredients and mix with a large wooden spoon or an electric mixer. Mix just until the ingredients are combined.

Step 5

The batter will be thick, but do not add any extra liquid.

Step 6

Stir in the chopped apples and nuts, then mix with a wooden spoon.

Step 7

Spread the batter evenly into the prepared pan.

Step 8

Bake at 325 degrees for about 35-40 minutes. If the top starts to brown too quickly, lay a piece of foil over it. The cake is fully baked with a toothpick inserted into the center comes out with a few crumbs on it or clean, but no raw batter.

Step 9

Once baked, set on a wire rack to cool for about 20 minutes while you make the glaze.

Step 10

Add the butter and brown sugar to a medium sized sauce pan and melt over medium heat. Stir often until the sugar melts and is mostly dissolved. This will take a few minutes.

Step 11

Turn the heat up to medium-high and add the milk, then let the mixture come to a soft boil. Let it boil for 30 seconds. Make sure to contantly stir. The mixture will foam up.

Step 12

Take the mixture off the heat source and add confectioner's sugar and mix well. Work quickly as the mixture will begin to thicken up. If there are confectioner sugar clumps, pour the mixture through a strainer to remove them. Work fast so the mixture doesn't thicken too much for you to pour onto the cake. Once the confectioner's sugar is mixed in well, immediately pour the glaze over the cake and spread evenly.

Step 13

(If the glaze thickens up too much before you can pour it over the cake, heat it in the microwave for about 15 seconds at a time and stir to thin out he consistency a bit.)
