Walnut Cake with Praline Frosting

I've had this recipe for quite a long time and had made it once, long before I was blogging recipes.  I remembered really liking it, so I decided to make it again--and glad I did!  It's quite tasty, and the walnuts make it perfect for fall :) 9/10

Ingredients:

cake--
9 oz. all-purpose flour
1/2 tsp. baking soda
1/2 tsp. salt
7 T. unsalted butter, softened
1 c. granulated sugar
1/4 c. brown sugar (packed)
2 large eggs
1 large egg white
1 tsp. vanilla extract
1 c. buttermilk
8 T. chopped walnuts, toasted, divided (part goes in frosting)

frosting--
1/2 c. brown sugar, packed
6 T. milk, divided
2 T. unsalted butter
1 T. light corn syrup
dash of salt
2 c. powdered sugar
1/2 tsp. vanilla extract

Directions:

1. Combine flour, baking soda, and salt in a medium bowl and set aside.  Grease a 9" x 13" pan and set aside.

2. In the bowl of a stand/electric mixer, beat together butter, sugar, and brown sugar until light and fluffy (around 3 minutes).

3. Beat in eggs one at a time, followed by egg white and vanilla extract.

4. Heat oven to 350°F.

5. Gradually mix in buttermilk and reserved flour mixture, alternating between the two, until well combined.

6. Fold in only 6 T. of the toasted walnuts (save rest for frosting).

7. Spread into prepared baking pan and bake for 28 min.

8. After cake has cooled, prepare frosting: In a medium saucepan over medium-high heat, combine the brown sugar, only 1/4 c, of the milk, butter, corn syrup, and salt.  Bring to a boil, stirring occasionally, then boil for 2 minutes.

9. Pour mixture into a heat-safe bowl.  Add the remaining 2 T. of milk and the powdered sugar.  Beat with a mixer on high speed until slightly cooled and thick (around 2 minutes).

10. Beat in the vanilla extract.  Spread frosting over cooled cake in an even layer, then top with remaining 2 T. of walnuts.  Let frosting set before cutting into squares.  Enjoy!
