Protein Oatmeal Cookies: Vanilla Oat Chews
These protein oatmeal cookies are a staple of American healthy baking, designed for use as a breakfast or a snack. They combine rolled oats and vanilla protein powder with mashed ripe banana to create a soft, chewy texture. The result is a dense, sweet treat with a savoury hint of peanut butter and the richness of dark chocolate chips.
Mash the banana until it is almost liquid to ensure the dough binds correctly without becoming lumpy. Do not press the dough down after placing it on the baking sheets; let them spread naturally at 180°C (350°F). If you skip the 2 minutes of resting on the sheet after baking, the cookies may break before they move to the wire rack. Let them cool completely to allow the centre to set.

Instructions
-
Prepare the oven
Preheat your oven to 180°C (350°F). Line two baking sheets with parchment paper so the cookies do not stick to the metal. This ensures an even bake and easy removal.
-
Mix wet bases
Whisk the egg and honey in a small bowl until the mixture is smooth and slightly frothy. Melt the coconut oil in a saucepan until it is liquid. Liquid oil incorporates more evenly into the dough.
-
Mash the banana
Mash the ripe banana in a large bowl until it is almost liquid. Stir in the whisked egg-honey mixture and the melted coconut oil. Combine these well to create a consistent wet base.
-
Combine dry ingredients
Stir in the peanut butter, vanilla protein powder, rolled oats, baking powder and salt. Mix until a thick, sticky dough forms. Fold in chocolate chips now if you want extra flavour.
-
Shape the cookies
Drop rounded teaspoons of dough onto the sheets, spacing them 6cm apart. Do not press them down. They will spread slightly on their own during baking.
-
Bake the dough
Bake for 12 minutes until the edges are lightly golden and the tops have set. The centres will remain soft. Do not overbake or you will lose the chewy texture.
-
Cool the cookies
Remove the sheets from the oven and let the cookies rest for 2 minutes. Transfer them to a wire rack to cool completely. This prevents the bottoms from becoming soggy.
If your dough feels too wet to hold a rounded shape, chill it for 30 minutes before baking. This firms the fats and ensures your cookies do not spread too thin in the oven, maintaining a thicker, chewier centre.
What to serve with it
Serve these cookies with Greek yoghurt and fresh berries to create a protein-packed breakfast. You may drizzle honey or maple syrup over the top for added sweetness. To balance the meal, pair one cookie with a hot cup of tea or coffee for a measured morning treat.
Storing and reheating
Keep cookies in an airtight container at room temperature for up to 7 days. For longer storage, wrap them individually and freeze for 3 months. Thaw a frozen cookie at room temperature for 20 minutes before eating to restore the soft, chewy texture in the centre.
