In a large bowl, whisk together melted butter, water, sour cream and sugar. Whisk in eggs, vanilla extract and almond extract. Then whisk in flour, baking soda and salt.
Pour batter into prepared jelly roll pan and bake for 20 minutes, or until a toothpick inserted in the center comes out clean.
Once cake is baked, whisk together melted butter, milk, vanilla extract, almond extract and powered sugar – until smooth. Pour on top of hot cake and spread icing out to the edges. Sprinkle with sliced almonds.
Notes
Storage: If stored in an airtight container, this cake is good for up to 5 days…but I promise it won’t last that long!
