Equipment

  • high-speed blender, immersion blender, or food processor
  • 10x8-inch baking dish (or anything similar)
  • Mixing bowls

Ingredients

For the oatmeal bake:

  • 2 cups gluten-free rolled oats (I like One Degree)
  • 1 teaspoon baking powder
  • 1 ½ teaspoons cinnamon
  • ¼ teaspoon nutmeg
  • ¼ teaspoon sea salt
  • 2 tablespoons ground flaxseed or hemp seeds
  • 1 ½ cups unsweetened almond milk (or milk of choice)
  • ½ cup unsweetened applesauce
  • 1 ½ large apples, divided — 1 grated (about 1 cup) and ½ thinly sliced for topping
  • 2 large egg whites (or 1 whole egg + 1 egg white)
  • 2 tablespoons pure maple syrup
  • 1 teaspoon vanilla extract
  • 2 tablespoons creamy almond butter or peanut butter
  • cup (about 25g) vanilla protein powder (optional; I like Ritual Protein)
  • ½ cup plain full-fat Greek yogurt (optional; replace ⅓ cup almond milk for added creaminess)
  • Optional Add-ins: ¼ cup chopped pecans or walnuts, ¼ cup raisins, or a sprinkle of oats + cinnamon for topping

For the date caramel:

  • ½ cup pitted Medjool dates (about 6 large)
  • 3 tablespoons warm water
  • 1 tablespoon creamy almond butter
  • ½ teaspoon vanilla extract
  • Pinch of sea salt

Instructions

  • Preheat the oven to 375°F.
  • Grease a 10×8-inch baking dish (or anything similar) with avocado oil spray or line with parchment paper.

Make the date caramel:

  • Add the dates, warm water, almond butter, vanilla, and salt to a high-speed blender, immersion blender cup, or food processor. Blend until smooth and creamy, scraping down the sides as needed.
  • Add a splash of more water if needed to thin. Set aside.

Mix the oatmeal base:

  • In a large bowl, combine oats, baking powder, cinnamon, nutmeg, salt, and flaxseed or hemp seeds.
  • In a separate bowl, whisk together almond milk, applesauce, grated apple, egg whites, maple syrup, vanilla, and nut butter until smooth.
  • Whisk in protein powder if using, along with an extra 2–3 tablespoons of almond milk to maintain a thick, but pourable batter. Stir in Greek yogurt, if using.
  • Combine the wet and dry ingredients: pour the wet mixture into the dry and stir until just combined. Fold in any add-ins if desired.

Assemble & Serve:

  • Pour half of the oatmeal mixture into the prepared baking dish and spread it evenly with a spatula.
  • Spoon 6–8 small dollops of date caramel over the surface, then use the back of a spoon to gently swirl it into the oats.
  • Pour the remaining oatmeal mixture on top and spread evenly.
  • If you have any caramel left, spoon it over the top and lightly spread.
  • Arrange the thinly sliced apple evenly over the surface (not overlapping), then sprinkle with cinnamon. Bake until golden and set.
  • Bake for about 40 minutes, or until the top is golden and the center is set. Let cool for at least 10 minutes before slicing.
  • Serve warm with an extra drizzle of caramel or nut butter. Enjoy!

To Store:

  • Keep in an airtight container in the fridge for up to 5 days.
  • Reheat in the toaster oven at 350°F for about 5–10 minutes, or in the microwave for 30–45 seconds.
