"This recipe would be great for a brunch, or for house guest. If available you can use fresh berries. For an extra tasty top, sprinkle a tablespoon or so of extra brown sugar."

    What is the liquid proportion if using steel cut oats? Also if using apple juice instead of milk? Thanks :)

    I also doubled the ingredients and baked in a 9x13. Baked perfectly! At least a dozen+ servings and everyone LOVED it! Will become a go to for bunches, house guests and holiday breakfasts! I just used blueberries for the fruit. Made easily VEGAN by using almond, soy or coconut milk and substituting the egg with applesauce!

    This is a popular recipe on the pinterest website and with good reason. It tastes like a big, soft delicious oatmeal cookie. I was particularly excited about how this turned out because I took a chance and doubled the recipe hoping that it would fit in a 9 inch x 13 inch glass baking dish. It fit perfectly and cooked up just fine in the same amount of time that the recipe specified.

    I originally found this on Urban Nester's blog and wanted to put it here for safe keeping! It is delicious!!! I used 1/3 cup brown sugar and fresh fruit. Thanks for posting this new family favorite!

    I made 2 batches at the same time for an office wedding shower. The first I used frozen blueberries and white chocolate chips ( a little extra of each) , and the second I used. Butterscotch chips and pecans. I need to work on the top a bit to make it more pleasing to the eye. And perhaps offer a little cream to add after serving, but overall, this recipe was like eating a warm cookie! I am usually not the biggest fan of oatmeal, but I plan on making another batch for my family tomorrow.

    This recipe is the bomb. I usually double the fruit. I use frozen blackberries, blueberries and raspberries, whatever I have on hand. I also throw in a little applesauce. Moist and delicious.
