Key Ingredients
- Rolled oats: The base of the baked oatmeal, giving it a tender, soft-baked texture that holds up well for meal prep. Use gluten-free oats if you’re gluten-intolerant.

- Sliced almonds: Mixed into the batter and sprinkled on top for crunch and a true almond croissant finish.
- Almond butter: Adds richness and helps bind the bars while giving them more almond flavor.
- Maple syrup: Pure Maple Syrup has natural sweetness that brings everything together with warm, caramel notes.
- Egg whites: A lean source of protein that keeps the texture soft without making the bars dense.

Tips & Variations
- Make it gluten-free: Use certified gluten-free rolled oats to keep this recipe fully gluten-free.
- Almond extract goes a long way: One teaspoon gives a classic almond croissant flavor. If your extract is very strong, reduce slightly to avoid overpowering the oats.
- Warm the almond butter: Slightly warm the almond butter before whisking. It blends more smoothly with the other wet ingredients.
- Make it less sweet: Reduce the maple syrup to 1⁄3 cup for a more lightly sweet breakfast bar.
Storage & Meal Prep
Store the baked oatmeal in an airtight container in the refrigerator for up to 4 days.
The squares hold their shape well and reheat quickly in the microwave or oven.
For meal prep, slice the bars and separate them with parchment paper so they are easy to grab throughout the week.
You can also freeze individual squares for up to three months and thaw them overnight in the fridge.
FAQ
Yes. Quick oats will work, but they create a softer, more uniform texture since they absorb liquid faster. If you prefer baked oatmeal that feels a little heartier with more structure, rolled oats are the better choice.
Yep, 1⁄3 cup works well if you prefer a lightly sweet version.
Definitely. Let it cool completely, slice it into squares, and freeze in an airtight container for up to three months. Thaw overnight in the fridge or reheat from frozen in the microwave for a quick breakfast.
A quick 15 to 20 seconds in the microwave warms it through without drying it out. You can also pop a square into an air fryer if you prefer crispier edges.
