In a large bowl, beat the first four ingredients on low speed for 30 seconds. Beat on medium for 2 minutes. Pour into prepared pans.
Bake at 350° for 20-25 minutes or until a toothpick inserted in the center comes out clean. Cool for 10 minutes before removing to wire racks to cool. Gently peel off waxed paper.
In a large bowl, whisk first four filling ingredients for 2 minutes (mixture will be thick). Fold in whipped cream.
Place one cake layer on a serving plate; top with half of the filling. Repeat layers. Top with the third cake layer. In a microwave-safe bowl, microwave the glaze ingredients, uncovered, at 30% power for 45 seconds; stir until smooth. Spread over top of cake.
