Using a standing mixer or a hand mixer, cream butter & sugar together. Add 5 large eggs, add & mix one egg at a time in order to create an emulsion. Add the zest of a lemon & a lime, vanilla extract & lemon extract & mix.
Add cake flour in increments of ⅓, mixing the flour into the batter in-between each increment. Once the cake flour is incorporated into the batter, add salt & sour cream and mix. While mixing the batter, slowly pour in the lemon-lime pop.
Line a Bundt cake pan with shortening & all-purpose unbleached flour. Pour the cake batter into the cake pan & bake for one hour in the center rack of the oven.
Test the center of the cake with a knife; if it comes out clean & dry then the cake is ready.
Remove the cake pan from the oven & allow it to cool for 10 minutes before removing the cake from the pan.
