To turn our loved Eggnog Poke Cake into a gluten-free version you just need to make a few simple substitutions. Start by selecting a gluten-free vanilla cake mix. There are plenty of options available that offer the same light and fluffy texture and delicious vanilla flavor as traditional mixes. When preparing the cake make sure to use a gluten-free flour blend, for dusting your pan to avoid any potential cross-contamination. As, for the pudding mix most vanilla pudding mixes are naturally free of gluten. It's always an idea to double-check the label for any hidden traces. The remaining ingredients – eggnog, spiced rum, whipped topping, cinnamon and nutmeg – are all naturally free of gluten.
