ANTS-ON-A-LOG CAKES

Steps:

• Trim the long sides of each pound cake at an angle using a serrated knife. Use the knife to carve out a 1/2-inch-deep, 2 1/2-inch-wide channel down the center of each cake.
• Cover the cakes with the frosting, leaving the bottom of the channel unfrosted. Use the back of a fork to make grooves in the frosting. Put the cakes in the freezer until the frosting sets, about 20 minutes.
• Meanwhile, make the peanut butter filling: Beat the butter and peanut butter in a large bowl with a mixer on medium-high speed until light and fluffy. Beat in the confectioners' sugar on low speed until smooth. Set aside.
• Mix a few drops of green food coloring in a small bowl with a drop of yellow food coloring and a splash of water. Brush onto the frosting. Adjust the color with more food coloring or water as needed.
• Spread the peanut butter filling into the channel in each cake using the back of a spoon.
• Arrange the prunes on top of the peanut butter filling.
