Carrot Cake Baked Oatmeal

Featured in: Weekend Rustic Recipes

This wholesome baked oatmeal brings together all the comforting flavors of carrot cake in a nutritious, meal-prep friendly format. Old-fashioned oats form the hearty base, while finely grated carrots add natural sweetness and moisture. Warm cinnamon and nutmeg create that classic spice blend everyone loves.

The preparation comes together quickly—just whisk together the wet ingredients, combine with the dry mixture and carrots, then bake until golden and set. Each serving offers a balanced start to the day with whole grains, protein, and vegetables disguised as a treat.

Top individual portions with Greek yogurt, a drizzle of maple syrup, or fresh fruit. The baked oatmeal keeps beautifully in the refrigerator for up to five days, making it ideal for preparing ahead and reheating throughout the week.

My apartment smelled like warm spices and butter the first Sunday I experimented with baking oatmeal instead of simmering it on the stove. Id been meal-prepping for the week ahead, tired of the same overnight oats rotation, when it hit me that carrot cake flavors would be brilliant in breakfast form. The way the cinnamon and nutmeg filled the kitchen made the whole experiment feel like baking for someone special, even though it was just me and my meal prep containers.

My sister texted me at work that same week asking what Id made because she could still smell the spices on my sweater from the morning. When I brought her a container to try, she called me two days later having made three batches for her roommates. Now whenever we visit each other, someone always has a dish of this waiting in the oven.

Ingredients

  • Old-fashioned rolled oats: These hold their texture better than quick oats during baking, giving you that perfect chewy-tender balance
  • Ground cinnamon and nutmeg: The warmth of these spices transforms ordinary oats into something cozy and aromatic
  • Baking powder: Creates a slight lift so the oatmeal bakes up fluffy rather than dense and heavy
  • Chopped walnuts or coconut: Add texture and richness, though the recipe works beautifully without them for a simpler version
  • Milk: Any milk works beautifully here, but whole milk or unsweetened oat milk gives the creamiest results
  • Maple syrup or honey: Just enough sweetness to feel indulgent while keeping breakfast nutritious
  • Grated carrots: Finely grated so they practically melt into the oatmeal, adding natural sweetness and moisture
  • Raisins: Plump up during baking creating little pockets of sweetness throughout

Last winter during finals week, my roommate and I survived almost entirely on this baked oatmeal. Wed study in the kitchen just to catch whiffs of it reheating, and somehow having something warm and spiced made those endless nights feel a little more manageable.

Make Ahead Magic

This might be the ultimate meal prep breakfast. I bake it on Sunday, portion into containers, and suddenly my weekday mornings feel luxurious instead of rushed. It actually tastes better on day two or three when the spices have had time to meld and deepen.

Serving Ideas

While its perfect straight from the dish, a dollop of Greek yogurt adds protein and tang that balances the sweetness. Sometimes I drizzle extra maple syrup over warm portions, especially if Im serving it to friends who havent tried it yet.

Customization Options

The base recipe is endlessly adaptable depending on what you have in your pantry or what youre craving. Ive swapped raisins for chopped dried figs, used pecans instead of walnuts, and even added a pinch of ginger when I wanted extra warmth.

  • Try adding shredded apple along with the carrots for extra moisture and fruity sweetness
  • A sprinkle of turbinado sugar on top before baking creates a delightful crispy crust
  • For extra protein, stir in a scoop of vanilla protein powder with the dry ingredients

Frequently Asked Questions

Can I make this baked oatmeal vegan?

Yes, simply replace the eggs with flax eggs (2 tablespoons ground flaxseed mixed with 5 tablespoons water) and use non-dairy milk. The texture remains just as satisfying.

How should I store leftovers?

Keep refrigerated in an airtight container for up to five days. Reheat individual portions in the microwave for 30-60 seconds or enjoy cold.

Can I use quick oats instead of old-fashioned?

Old-fashioned rolled oats work best as they maintain texture during baking. Quick oats may become too soft and mushy in the finished dish.

What can I use instead of maple syrup?

Honey works as a direct substitute. For a lower-sugar version, reduce the sweetener to 2 tablespoons or replace with mashed banana.

Can I freeze this baked oatmeal?

Absolutely. Cut into individual portions, wrap tightly, and freeze for up to three months. Thaw overnight in the refrigerator before reheating.

What nuts work best in this recipe?

Walnuts complement the carrot cake flavors perfectly, but pecans make an excellent alternative. Omit nuts entirely for a nut-free version.
