Try this Cherry Vanilla Coke Poke Cake recipe.
A bright crimson crumb structure absorbs pockets of set cherry gelatin while remaining structurally intact beneath a billowy layer of pudding frosting. Baking in standard quarter-sheet metal pans rather than heavy glass allows the sponge to bake evenly without over-browning the edges. Standard dairy milk interacts with instant vanilla pudding to yield a stable structure, but unsweetened almond milk works as an alternative if the gelling agents are monitored closely. When adapting this procedure for smaller households, divide the dry cake mix by weight on a digital scale rather than attempting to eyeball fractional portions of powdered mixes.
Allowing the baked sponge to rest for exactly 15 minutes before poking prevents the crumb from sticking to wooden spoon handles. Poking holes spaced one inch apart ensures the liquid distributes uniformly rather than pooling in large cavities. Chill the gelatin-soaked base for 30 minutes at 38 degrees Fahrenheit to guarantee the cola-flavored liquid firms adequately before the topping goes on.
