Chocolate-Glazed Maple Spice Cake

I'm not usually a maple spice cake person, but this Chocolate-Glazed Maple Spice Cake is terrific. My neighbor Chris Gold recently made it and brought over a huge piece. Chris usually makes new recipes several times until she feels she gets it right, and there were several versions of this recipe to try. Here's the final version that she tweaked from the original recipe she found in Family Circle. Here's the link to the original recipe. Chris's recipe is below. This cake would be great to serve at Thanksgiving dinner or have ready for the post-Thanksgiving feast! It's a touch of Fall!

CHOCOLATE-GLAZED MAPLE SPICE CAKE

Ingredients
3 cups all-purpose flour
1 tablespoon baking powder
2 teaspoons pumpkin pie spice
3/4 teaspoon salt
1 cup solid vegetable shortening
1 cup packed dark-brown sugar
3/4 cup maple syrup
3 eggs
1 teaspoon imitation maple flavor
3/4 cup milk

Filling: 
8 ounces cream cheese, softened
1/4 cup (1/2 stick) unsalted butter, softened
1/2 teaspoon imitation maple flavor
1 1/2 - 2 cups confectioners' sugar

Frosting: 
1/2 cup heavy cream
1 cup semisweet chocolate chips
1 heaping Tbsp unsweetened cocoa
1 tsp vanilla

Whole walnuts, to garnish

Directions 
Heat oven to 350 degrees F. Coat three 8 x 2-inch round layer-cake pans with shortening; dust with flour, discarding excess.

Cake: 
Whisk flour, baking powder, pumpkin pie spice, and salt in bowl.
Beat shortening in second bowl until smooth and creamy. Beat in sugar and maple syrup. Add eggs, one at a time, beating after each. Add maple flavor; beat until smooth. On low speed, beat in half of the flour mixture, then milk, then remaining flour mixture.
Spread batter in prepared pans, dividing evenly.
Bake at 350 degrees F for 25 to 28 minutes, until golden brown. Cool in pans on rack 10 minutes. Remove cakes directly to rack to cool completely.

Filling: 
Beat cream cheese, butter, and maple flavor in bowl until smooth. Add sugar; beat until good spreading consistency.
Place cake layer on serving dish. Top with 1-1/4 cups filling. Place second cake layer on top, then remaining 1-1/4 cups filling. Top with third layer.

Frosting: 
In saucepan, heat cream just to a simmer. Pour over chocolate and cocoal in small bowl; whisk until smooth. Add vanilla and stir. Cool 5 minutes, until thicker but still pourable. Pour over cake, spreading to allow some to dribble down sides. Top with walnuts.

Refrigerate 15 minutes before serving.

Note 
For sparkly walnuts, brush with corn syrup; dust with gold sanding sugar, available at: countrykitchensa.com.
