Apple cinnamon baked oats
Sliceable egg-free baked oats with diced apples, chia, and cinnamon.

These baked oats have a moist, spoonable middle and firmer edges, with pieces of apple throughout. The batch makes four breakfast portions from one dish. Cinnamon and maple syrup season the oats, while soy milk and chia hold the mixture together as it bakes and rests.
Getting a slice that holds together
Rolled oats keep some chew after baking. Chia absorbs liquid around the flakes, helping the center settle into a slice once it cools. Stir the dry ingredients together before adding the milk so the chia and baking powder spread through the dish. A pocket of dry chia can leave a gummy patch beside oats that need more moisture.
The ten-minute rest is part of the method. Cutting straight from the oven lets the hot center slump before it has settled. Look for a set middle with no loose milk pooling when you gently tilt the dish. The edges can brown before the center is ready, especially in a deep or narrow baking dish.
Apples, milk and the grocery bill
Cut the apples into small, similar pieces so each portion contains fruit and the pieces soften during the bake. Firm apples give more distinct bites; softer eating apples blend into the oats. Leaving sound, washed skin on saves peeling and keeps the preparation short. Remove the core before weighing the fruit.
Plain rolled oats usually give more control over sweetness than flavored oatmeal packets. Compare the cost by weight, and buy a larger bag only if you will use it. The listed soy milk also affects the nutrition. The FDA explains that plant beverages vary in protein and added nutrients, so check the carton when choosing a substitute. Oat milk is an option here, with a different nutritional result.
Four portions without dry edges
After the bake has rested, divide it into four portions rather than repeatedly reheating the whole dish. Refrigerate within two hours and use within three days. A shallow container helps each portion cool without a thick, warm center remaining under the surface.
For reheating, cover a portion loosely and heat until steaming throughout. A small splash of the same plant milk can loosen oats that have become firm in the refrigerator. Cold portions will have a denser texture and can be eaten with a spoon. Keep any extra topping separate until serving so the stored oats retain their original moisture balance.
