Add eggs to medium bowl and briefly whisk. (Using a fork is fine.)
Add the remaining ingredients and combine well.
Scoop ingredients into paper muffin cases or small greased ramekins.
Bake for 25 minutes.
Remove from the oven and allow a few minutes to cool (those choc chips are HOT), then enjoy!
Notes
You can use any type of flour that suits you. This recipe works well with wholemeal flour. I personally enjoy the nuttiness of almond flour and sometimes add a dash of almond extract, too, to enhance that flavor.
You could add slivered almonds or any chopped nuts, like pecans or walnuts instead of (or as well as!) the chocolate chips.
Try adding 1/3 cup raisins or any dried and diced fruit.
To make the baked oats more savory, omit the maple syrup and add 1/2 cup of sliced and sautéed mushrooms/ cherry tomatoes/ baby spinach/ corn kernels.
For another savory option, dice and lightly fry some bacon and onion and add them to the oat mixture before baking.
