To make our cherished Butter Pecan Praline Poke Cake suitable, for gluten-free diets just a few simple adjustments are needed. Start by substituting the butter pecan cake mix with a gluten-free alternative as there are several brands available that offer equally delicious options without compromising on taste or texture. Additionally ensure that the coconut pecan frosting you use is gluten-free by checking the label although many options already meet this requirement. As for the sauce both butter and sweetened condensed milk are naturally gluten-free so there's no need to worry there. However it's important to be cautious, about the pecans. Check that they haven't been processed in a facility where products containing gluten are handled to avoid any cross-contamination risks.
