I came across this delicious looking recipe on Pinterest. So I made it tonight and ate it right out of the oven. Well, I did let it cool down a bit! It is gluten free but I'm sure it could easily have the GF flour mix substituted for wheat or whatever flour you wanted. We ate it without ice cream and it was delicious!
You can see in the photo that the sauce is peeking through in a couple of places. It's kind of a messy cake to make but totally delicious. I think you could probably use just about any GF flour mix...there are so many recipes to make from scratch or premade mixes to buy ready to go.
Here's the link to the recipe:
