3-Ingredient Banana Oatmeal Cookies (Beta-Glucan Protocol)
A highly viscous, beta-glucan-rich soluble fiber protocol utilizing exactly three ingredients. By harnessing the natural starch retrogradation of heavily speckled bananas and the structural integrity of old-fashioned rolled oats, this recipe delivers a zero-cholesterol, heart-healthy matrix without the need for eggs, flour, or refined sugars.
Ingredients
- 2 large Ripe Bananas Must yield exactly 1 ½ cups mashed. Use heavily brown-speckled bananas for maximum starch-to-sugar conversion.
- 1 ½ cups Old-Fashioned Rolled Oats Do NOT substitute quick oats; thick rolled oats are crucial for structural integrity and beta-glucan efficiency.
- ⅓ cup Dark Chocolate Chips 70% cacao or higher. Use certified dairy-free chips to maintain strict vegan compliance.
Instructions
- Preheat your oven to 350°F. Line an aluminum baking sheet with parchment paper.
- Peel the heavily speckled bananas. Using your heavy-duty fork, mash them against the bottom of the glass bowl until they form a wet slurry with small, uniform lumps.
- Pour the 1 ½ cups of old-fashioned rolled oats directly into the banana slurry. Use your silicone spatula to fold the mixture until every oat is coated. Let it rest for 60 seconds to allow the starches to hydrate.
- Pour the ⅓ cup of dark chocolate chips over the dough. Gently fold 4 to 5 times until the chips are evenly distributed. Do not overmix.
- Drive your spring-release cookie scoop into the bowl, packing the dough tightly against the side to force out air pockets. Release the dense domes onto the parchment paper, spacing them 2 inches apart.
- Using the flat of your palm, fork or fingers, press each dough dome down into a flat, ½-inch thick disc. (Crucial: Because this formula lacks chemical leaveners, these will not spread during baking. They will retain their exact pre-baked shape).
- Place the baking sheet on the center oven rack. Bake for 10 to 12 minutes at 350°F, until the edges of the oats toast to a golden-brown indicating a successful Maillard reaction.
- Remove from the oven. Do not touch or move them. Let the fragile starch bonds set on the baking sheet for exactly 10 minutes before transferring them to a wire cooling rack with a spatula.
Notes
- Storage Protocol: Moisture migration is your primary concern. Store fully cooled cookies in a square glass airtight container in the refrigerator for up to 4 days. Do not store at room temperature due to the high water activity of the fresh fruit.
- Freezing Protocol: The hydrated oat matrix handles freezing well. Place parchment paper between the layers in your airtight container. Freeze for up to 1 month. Thaw in the refrigerator overnight.
- Ingredient Warning: Altering the 1 ½ cup volume requirement for either the wet binder (bananas) or the dry matrix (oats) will result in structural failure. Measure exactly.
