Step 1

Preheat oven to 350°F. Spray a 9x13 pan with non-stick spray or use the butter & flour method.

Step 2

In a large bowl add the butter and brown sugar. Using a hand-held mixer, cream them together until they are lighter and fluffier.

Step 3

Add the eggs and vanilla to the butter mixture and mix until fully combined, 1-2 minutes. Scrape down the bowl as needed.

Step 4

Add the flour, baking powder, and salt to the bowl and mix on medium-low until just combined.

Step 5

Add in the zucchini and mix on low. It should be a runny mixture. If it appears dry at all, let it sit for 5 minutes.

Step 6

Add in 1 cup of butterscotch morsels and stir with a spatula.

Step 7

Pour the batter into the prepared pan and then top with remaining butterscotch morsels.

Step 8

Bake for 40 minutes and check for doneness. An inserted toothpick should be removed with a few crumbs on it, but not wet batter. It should appear dark on top and the edges. (This is good!)
