I made this cake for my dad's birthday! It turned out moist and delicious, no one would have guessed it was gluten-free.
It does have to sit overnight, so it does involve some planning ahead, but well worth it.
Toffee Poke Cake
1 GF chocolate cake mix (your favorite)
1 can (14oz) sweetened condensed milk
1 small jar caramel ice cream topping
Toffe Bits or crushed Heath/Skor candy bar
Make the cake according to package directions. When cake is done, poke holes all over the top with a large serving fork. (Poke alot of holes.) Pour the entire can of sweetened condensed milk over the top and let it soak in. Then pour the caramel over the top. Cool and refrigerate.
Top with Cool Whip and toffee bits.
