Root Beer Float Poke Cake with Vanilla Pudding

A nostalgic dessert that captures the classic root beer float experience in cake form. Moist chocolate cake gets infused with concentrated root beer syrup, then layered with creamy vanilla pudding and fluffy whipped topping. The poke cake technique allows the root beer flavor to penetrate throughout, creating pockets of sweet, fizzy goodness in every bite. Perfect for summer gatherings, birthday parties, or whenever you want to bring back childhood memories with a fun twist on traditional cake.

Tips

Tip 1

Make sure holes are deep enough for the root beer syrup to penetrate - go about 3/4 through the cake thickness.

Tip 2

Don't skip reducing the root beer - this concentrates the flavor and prevents the cake from becoming soggy.

Tip 3

Chill the cake for at least 2 hours before serving for best texture and flavor development.

How long will this cake keep?

Can I freeze this cake?
