Combine first 5 ingredients in a large mixing bowl. Beat at medium speed with an electric mixer 2 minutes. Stir in 1/2 cup chocolate mini-morsels. Pour batter into a greased and floured 12-cup Bundt pan.
Bake at 350° for 33 to 35 minutes or until cake springs back when lightly touched. Cool in pan on a wire rack 10 minutes; remove cake from pan, and cool completely on wire rack.
Combine butter, brown sugar and 2 tablespoons milk in a heavy saucepan over medium-low heat, stirring constantly, until sugar is melted. Remove from heat; stir in vanilla. Gradually stir in powdered sugar; if necessary, add remaining 1 tablespoon milk, stirring to desired consistency. Drizzle glaze over cooled cake.
Microwave remaining 1/2 cup chocolate morsels and shortening in a small bowl on HIGH 30 seconds or until melted. Pour melted chocolate into a small zip-top freezer bag. Snip 1 corner of bag, and drizzle over brown sugar glaze. Sprinkle almonds on cake.
Tip: For a thinner glaze, add more milk, 1 teaspoon at a time.
