Step 1
Preheat the oven to 400 degrees F (200 degrees C). Grease a rectangular baking dish with butter.
Step 2
Cream 1 cup plus 2 tablespoons butter and sugar in a bowl with an electric mixer until smooth. Add eggs one at a time beating well after each addition. Combine flour and baking powder in a separate bowl and mix into the batter 1/4 cup at a time. Beat in lemon zest. Pour batter into the prepared baking dish.
Step 3
Bake in the preheated oven until a toothpick inserted into the center comes out clean 40 to 45 minutes. Cool on a wire rack for 5 minutes. Run a table knife around the edges to loosen. Invert carefully onto a serving plate or cooling rack. Let cool completely 30 minutes to 1 hour.
Step 4
Combine cream cheese and butter in a bowl and beat with an electric mixer until creamy. Add confectioner's sugar 1/4 cup at a time alternating with lemon juice mixing until frosting has the desired consistency.
Step 5
Poke holes 2 to 3 inches apart into 1 side of a styrofoam block using a lollipop stick.
Step 6
Trim off tops and sides of the cake. Crumble the cake into very fine crumbs using your hands. Mix in 2 tablespoons frosting until thoroughly combined. Add more frosting if necessary until mixture is smooth and sticks together.
Step 7
Line a baking sheet with waxed paper. Roll the cake mixture into walnut-sized balls. Arrange cake balls on lined baking sheet and refrigerate for 30 minutes.
Step 8
Melt 1/4 of the confectioners' coating in a microwave-safe glass or ceramic bowl in 15-second intervals stirring after each melting 1 to 3 minutes.
Step 9
Poke a small hole into each cake ball with a lollipop stick. Dip lollipop sticks into the confectioners' coating and stick one into each cake ball. Refrigerate for 30 minutes.
Step 9
Melt remaining confectioners' coating in a microwave-safe glass or ceramic bowl in 15-second intervals stirring after each melting 1 to 3 minutes. Dip cake balls into the coating; tap to remove excess coating. Scatter sprinkles over the cake balls. Stick cake pops upright in the prepared foam block. Allow to dry completely.
