Cook Using Your Preferred Method
OVEN: Bake 25-35 minutes until top is browned, crackled, and springs back when pressed. AIR FRYER: Preheat to 180C, bake 8-15 minutes (check at 8 mins). MICROWAVE: Cook on high 3-4 minutes for softer texture.

Remove from heat and let stand 2-5 minutes. This prevents soggy bottom and allows oats to firm up into sliceable cake texture. Serve with extra fruit or a dollop of yogurt.

Frequently Asked Questions
What is the difference between cake and chewy texture?
The TikTok cake style uses blended oats (processed into fine flour) which creates a light, fluffy, muffin-like crumb. The classic chewy style uses whole rolled oats for a hearty, bread pudding or flapjack texture. Both use the same ingredients - only the preparation differs.
Why are my baked oats soggy or mushy?
Two common causes: 1) Undercooking - ensure a toothpick comes out clean from the center. 2) Using fruit that releases too much liquid like over-ripe bananas. The crucial fix is to let it cool for 2-5 minutes after baking - the texture sets significantly during this resting period.
Can I add protein powder to baked oats?
Yes! Adding protein powder creates a fudgy, dense texture. However, protein powder absorbs liquid, so add an extra 2-3 tablespoons of yogurt or milk to compensate. Start with 15-20g protein powder and adjust to taste. Check syn values for your specific brand.
How do I meal prep baked oats for the week?
Make a batch of 5 portions on Sunday. Store in airtight containers in the fridge for 3-5 days, or freeze for up to 3 months. Reheat individual portions in the microwave for 1-2 minutes. You can also mix dry ingredients the night before and bake fresh each morning.
Can I make baked oats overnight?
Yes! Mix all wet and dry ingredients together the night before and store in the fridge. The oats will soften overnight. In the morning, simply pour into your ramekin and bake as normal. This overnight prep actually enhances the texture for some people.
What are the best mix-in combinations?
Popular combinations include: Apple and Cinnamon (grated apple + 1 tsp cinnamon), Chocolate (1 tbsp cocoa + chocolate chips), Berry Blast (mixed berries + vanilla), Banana Bread (mashed banana + walnuts - check syns), and Carrot Cake (grated carrot + mixed spice + raisins).
