    This looks like a really good recipe. If you take out the brown sugar and the orange juice, then on WW (Weight Watchers) “purple” plan, then it would be a “zero point” food (not free). What would happen if I took those two ingredients out? Should I add more fruit? I eat oatmeal every day for breakfast – and usually 2 or 3 eggs (on WW, those are “zero points”). My internist (primary care physician) is glad I lost 50 lbs so far, and he wants me to lose 45 more. I am a 54 year old male. I am on no medications, and my lab results and blood pressure are now normal – with diet and exercise alone!

    Another thing my doctor wants is for me to eliminate “added sugar”. (Note: On WW, eating an orange is “zero points” but a glass of orange juice is 6 points – an orange fills you up more).

    This is a serious question for me since my diet and exercise regimen has done for me what it takes pharmaceuticals to do for many others. Nutrition is powerful medicine.

    Thanks! I may try out this recipe without the orange juice and brown sugar – just let me know what you think.

      Wow, I love hearing about your great success. I’ve made this recipe with milk instead of OJ and it’s quite good. I think you’ll need some sweetener, so I suggest using whatever no calorie or low calorie sweetener you prefer. I’m anxious to hear how your changes work out. I always say that a recipe is a guide, not a contract.

        Hi Jill, as you offered I used the recipe as guide; I dropped the oj, used water, and added nuts, as well as dried apricot. I had no vanilla essence, and ran out of cinnamon, so I topped up with chinese 5 spice and a little cayenne…true confession, wasn’t sure about the size of my egg, so I used 2 and reduced the amount of water.

        From my pov it worked out really well, I lost the sugar, and gained some fibre, and for me the fruit, nuts and spices took away the need for a sweetener of some kind.

        Will definitely be using your recipe again, the eggs and bicarb made the bake lighter than I expected…I think I was expecting something denser like flapjack.

        As you said it is very enjoyable warm with yoghurt; tomorrow I’ll take a piece to work to fill a corner.

        Thank you 🙂

          I LOVE that you did this. And thank you so much for sharing your success. I hope others will take it as inspiration. I sure will. I always say that a recipe is a guide, not a contract.

    Hi, fellow RD here! For those seeking a baked oatmeal that uses less added sugar, I would recommend substituting the OJ with milk, non-dairy milk, or water. And I would limit the sugar to 1 tbsp. I understand the recipe makes 9 squares, which amounts to only 8grams of sugar per serving (not including the OJ), but I’m thinking 1/9 of this recipe might not be filling enough. So people might consume more, upping their added sugar intake. I make a similar baked blueberry oatmeal that uses the same amount of oats, milk instead of OJ, only 20 grams (About 4 tsp) of maple syrup, 2 eggs, some nuts and oil, and it’s sweet enough and filling for my family of 4. It makes 4 large servings at only 4.5 grams of sugar per serving.

      Thanks for these ideas! I’ve made versions with milk, milk and OJ, various and fruits and nuts. All of them turned out great. I like to serve it with Greek yogurt on top. A scrambled egg or two would really round out the meal.
