Whiskey Pecan Cake

First time making this and loved it! I prefer gluten free cake mixes because they are denser and seem more moist.

Ingredients:
1 package white cake mix
1/2 cup chopped pecans
1/4 cup butter
1/2 cup sugar
1/2 cup + Whiskey

Mix the cake batter as directed. Stir in nuts and bake also as directed.
Combine butter, sugar and whiskey in a pot and boil for 5 minutes. When cake is done baking-pour mixture (carefully) over cake and bake 5 to 10 more minutes. Let cool.
I also poured a little more whiskey on after it was cooled and made a Whiskey frosting by combining 2 cups powdered sugar, 1-2 TBSP whiskey and 1 TBSP corn starch. Then I topped with coconut because I like coconut.
