1.5-2 cups of flour
2-3 cans of tuna (not drained)
Bake at 375 for 15-25 minutes stick a fork in it and make sure it pulls out clean. Similar to brownies.
You want the consistency to be very thick almost dough like not runny at all or it will crumble once it’s baked. It’s a great treat and dogs love it.
