Loaded oatmeal breakfast cookies are a hearty, portable breakfast made from oats, mashed banana, nut butter, and a mix of add-ins like nuts, seeds, and dried fruit. They are soft, chewy, and naturally sweetened, perfect for busy mornings or a post-workout snack. This recipe is flexible and comes together in one bowl with no refined flour or added sugar.
Serves 12 · Prep 15 min · Cook 15 min · Total 30 min
Ingredients
- 2 large ripe bananas, mashed (about 1 cup / 240 g)
- 1/2 cup (128 g) creamy peanut butter or almond butter
- 1/4 cup (60 ml) honey or maple syrup
- 1 large egg
- 1 teaspoon vanilla extract
- 2 cups (180 g) old-fashioned rolled oats (not instant)
- 1 teaspoon ground cinnamon
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup (60 g) chopped walnuts or pecans
- 1/4 cup (30 g) dried cranberries or raisins
- 1/4 cup (40 g) dark chocolate chips (optional)
- 2 tablespoons (14 g) ground flaxseed or chia seeds (optional)
Instructions
- Preheat your oven to 350°F (175°C). Line a large baking sheet with parchment paper or a silicone mat.
- In a large mixing bowl, mash the bananas with a fork until mostly smooth. Add the peanut butter, honey, egg, and vanilla. Whisk until well combined and creamy.
- Add the oats, cinnamon, baking soda, and salt. Stir with a spatula until everything is evenly moistened. Fold in the walnuts, dried cranberries, chocolate chips (if using), and flaxseed (if using). The dough will be thick and slightly sticky.
- Scoop about 2 tablespoons (about 30 g) of dough per cookie and drop onto the prepared baking sheet, spacing them about 2 inches apart. Flatten each cookie slightly with the back of a spoon or your palm to about 1/2-inch thickness.
- Bake for 12–15 minutes, until the edges are golden and the tops are set. The centers will still be soft but will firm up as they cool.
- Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely. They will be delicate when warm but firm up as they cool.
Tips
- Banana ripeness: Use very ripe bananas with brown spots for maximum sweetness and moisture. Less ripe bananas will make the cookies less sweet and more crumbly.
- Don’t overbake: These cookies are meant to be soft. Overbaking will make them dry. Pull them out when the edges are just golden and the center still looks slightly underdone.
- Flattening: Because these cookies don’t spread much, flattening them is essential for even baking. If you skip this, you’ll get thick, doughy mounds.
- Mix-ins: Feel free to swap the nuts and dried fruit for whatever you have—sunflower seeds, shredded coconut, or chopped dates all work well. Just keep the total mix-ins to about 1 cup (150 g) to avoid the cookies falling apart.
Serving Suggestions
Enjoy these cookies on their own as a grab-and-go breakfast, or pair them with a glass of milk, a dollop of Greek yogurt, or a piece of fresh fruit for a more complete meal. They also make a great pre- or post-workout snack.
Variations
- Vegan: Replace the egg with 1 tablespoon ground flaxseed mixed with 3 tablespoons water, and use maple syrup instead of honey. The cookies will be slightly denser but still delicious.
- Gluten-free: Use certified gluten-free rolled oats. Note that some brands of oats may be cross-contaminated with wheat, so check the label.
- Apple cinnamon: Add 1/2 cup (60 g) finely chopped apple and increase cinnamon to 1 1/2 teaspoons. Omit the chocolate chips for a more breakfast-like flavor.
- Protein boost: Stir in 2 tablespoons of your favorite protein powder. You may need to add 1–2 tablespoons of milk to keep the dough moist.
Storage and Reheating
Store the cookies in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 1 week. They also freeze beautifully—place them in a single layer in a freezer-safe bag or container for up to 3 months. To reheat, microwave a cookie for 15–20 seconds, or warm in a toaster oven at 300°F (150°C) for 5 minutes. The texture will be soft and almost like fresh-baked.
Frequently Asked Questions
Can I use quick oats instead of rolled oats? Yes, but the texture will be softer and less chewy. The cookies may also spread more, so keep an eye on them and reduce baking time by 1–2 minutes.
Can I make these without eggs? Absolutely. Replace the egg with a flax egg (1 tablespoon ground flaxseed + 3 tablespoons water, let sit for 5 minutes). The cookies will be a bit more fragile, so let them cool completely before handling.
Why are my cookies crumbly? This usually happens if the bananas are not ripe enough, or if you used too many dry mix-ins. Ensure your bananas are very ripe and measure the oats accurately. If the dough seems dry, add a tablespoon of milk or extra nut butter.
Can I use a different nut butter? Yes, almond butter, cashew butter, or sunflower seed butter all work. Sunflower seed butter will change the color (cookies may turn greenish due to a natural reaction with baking soda—this is harmless).
Are these cookies healthy? They are made with whole grains, fruit, nuts, and no refined sugar, but they are still a calorie-dense food. Enjoy them in moderation as part of a balanced diet.
Can I make the dough ahead of time? Yes, you can refrigerate the dough for up to 2 days. When ready to bake, scoop and flatten as directed, and add 1–2 minutes to the baking time if the dough is cold.
