Step 1

Prepare the Cakes: Preheat oven to 325°F. Grease and flour 12 mini Bundt pans.

Step 2

Whisk together flour, baking powder, baking soda, and salt in a bowl.

Step 3

Beat sugar and butter with an electric mixer on medium speed  until light and fluffy, 4 to 5 minutes. Add eggs, 1 at a time, beating well after each addition.

Step 4

Add flour mixture and sour cream to sugar mixture in 5 additions, beginning and ending with flour mixture. Add orange zest and almonds, and beat on medium speed until combined.

Step 5

Divide batter evenly among prepared Bundt pans, and smooth tops. Bake in preheated oven until a wooden pick inserted in center comes out clean, 16 to 18 minutes. Let stand in pans on a wire rack 10 minutes; remove from pans to wire rack.

Step 6

Prepare the Glaze: Combine sugar, orange liqueur, and orange juice in a small saucepan; bring to a boil over medium, stirring constantly until sugar dissolves. Brush hot Glaze over warm Cakes.

Step 7

Beat heavy cream and powdered sugar with electric mixer on high speed until medium peaks form, about 3 to 4 minutes. Top each of the glazed Cakes with a dollop of whipped cream, and garnish with orange segments.
