# What Goes In:

→ Oat Base

01 - 2 cups rolled oats
02 - 1 cup unsweetened almond milk
03 - 2 large eggs
04 - 1 cup plain Greek yogurt
05 - 1/4 cup vanilla or unflavored protein powder
06 - 1/4 cup maple syrup
07 - 1 teaspoon vanilla extract
08 - 1 teaspoon baking powder
09 - 1/4 teaspoon salt

→ Cinnamon Swirl and Crumble

10 - 1/3 cup brown sugar
11 - 2 teaspoons ground cinnamon
12 - 2 tablespoons melted unsalted butter
13 - 2 tablespoons all-purpose flour
14 - Pinch of salt

# How to Make It:

01 - Preheat oven to 350°F. Grease an 8x8-inch baking dish with cooking spray or butter.
02 - In a large bowl, combine rolled oats, almond milk, eggs, Greek yogurt, protein powder, maple syrup, vanilla extract, baking powder, and salt. Stir until all ingredients are well incorporated.
03 - In a separate small bowl, combine brown sugar, ground cinnamon, melted butter, flour, and salt. Mix until the mixture resembles wet sand.
04 - Pour half of the oat mixture into the prepared baking dish. Distribute half of the cinnamon crumble evenly over the oat layer.
05 - Pour the remaining oat mixture on top and finish with the remaining cinnamon crumble.
06 - Using a knife, gently swirl the crumble through the oat mixture to create a marbled pattern.
07 - Bake for 30 to 35 minutes until the top is golden brown and the center is set.
08 - Remove from oven and allow to cool for 10 minutes before cutting into portions and serving.

# Expert Tips:

01 -
  • It tastes like indulgence but delivers serious protein, making it the breakfast that finally satisfies both your taste buds and your fitness goals.
  • The cinnamon swirl creates this magical marbled effect that somehow makes a humble baked oat dish feel elegant and special.
  • You can make it once and eat it throughout the week, which means mornings actually become simpler instead of more complicated.
02 -
  • The protein powder you choose matters more than you'd think—some brands leave a chalky aftertaste that overpowers the cinnamon, so if your first attempt tastes off, try a different brand before blaming the recipe.
  • Don't skip the cooling time; I learned this the hard way by cutting into a warm cake and watching it crumble into a sad pile, when waiting those 10 minutes would have given everything time to set properly.
03 -
  • If you're making this specifically for meal prep, slice it into portions while it's still slightly warm—it cuts cleaner than when it's completely cold and hard.
  • The crumble texture depends on not over-mixing; overmix and it becomes a dense, greasy layer instead of a light, nuanced topping that adds textural interest.
