Preheat your oven to 350°F (175°C). Lightly grease an 8x8-inch baking dish with coconut oil or cooking spray.
Grab your blender and add half of the rolled oats (about 1 cup). Blend until they become a fine flour – this magic trick makes your baked oatmeal extra soft and fluffy!
In a large bowl, whisk together the remaining whole oats, the oat flour you just made, baking powder, salt, and vanilla protein powder.
Now, stir in the unsweetened almond milk, eggs, melted Biscoff spread, maple syrup, and vanilla extract. Mix everything until it’s smooth and beautifully combined.
Gently fold in the crushed Biscoff cookies. These add a delightful crunch and extra cookie butter magic!
Pour your delicious mixture into the prepared baking dish. If you like, sprinkle a few more crushed Biscoff cookies on top for extra charm.
Bake for 25-30 minutes, or until the top is golden brown and the center looks set. Don't overbake to keep it wonderfully moist!
Let it cool for a few minutes before slicing and serving warm. For an extra treat, drizzle with a little more melted Biscoff spread, a dollop of Greek yogurt, or your favorite nut butter!
