- 1 cup chocolate chips
- 1 package (8.5 ounces) Reese’s Baking Cups and Pieces, cut the peanut butter cups in half
Instructions

- In a separate bowl, stir together the baking powder, baking soda, salt, flour, and quick oats.
- Gradually add the dry ingredients to the butter mixture, mixing until just combined.
- Gently fold in the chocolate chips and Reese’s Baking Cups and Pieces.
- Reserve a few chocolate chips and Reese’s pieces to press onto the tops of the cookies if desired.
- Drop spoonfuls of dough onto the prepared baking sheet, leaving space between each cookie.
- Bake for about 10 minutes, or until the edges are lightly browned.
- Let the cookies cool on the baking sheet for 2–3 minutes.
- Carefully transfer the cookies to a wire rack and allow them to cool completely.
- Store cooled cookies in a tightly sealed container.
Serving and Storage Tips
- Serve the cookies slightly warm for a soft, gooey texture.
- Pair them with a glass of cold milk, coffee, or hot chocolate.
- For an extra peanut butter flavor, drizzle cooled cookies with melted peanut butter.
- Store the cookies in an airtight container at room temperature for up to 4–5 days.
- Place parchment paper between layers if stacking the cookies.
- For longer storage, freeze the cooled cookies in a freezer-safe container for up to 3 months.
- Thaw frozen cookies at room temperature or warm them briefly in the microwave.
- You can also freeze portions of cookie dough and bake them later when needed.
Variations
- Dark Chocolate Peanut Butter Banana Cookies
Replace the regular chocolate chips with dark chocolate chips for a richer, slightly less sweet chocolate flavor. - Milk Chocolate Banana Cookies
Use milk chocolate chips instead of semisweet chips for a sweeter, creamier cookie that pairs beautifully with the banana. - Chocolate Peanut Butter Cookies
Add 2–3 tablespoons of unsweetened cocoa powder to the dry ingredients for a chocolate-based version with even more peanut butter flavor. - Peanut Butter Chip Cookies
Replace half of the chocolate chips with peanut butter chips for an extra creamy peanut butter taste. - Banana Walnut Oatmeal Cookies
Add about ¾ cup chopped walnuts to the dough. The walnuts provide a crunchy contrast to the soft cookies. - Banana Pecan Cookies
Substitute chopped pecans for the walnuts. Toasting the pecans beforehand gives the cookies an especially delicious nutty flavor. - Coconut Peanut Butter Cookies
Add ½ cup sweetened or unsweetened shredded coconut to the dough. Coconut works especially well with banana and peanut butter. - Cinnamon Banana Oatmeal Cookies
Add 1 teaspoon ground cinnamon to the dry ingredients. For a warmer flavor, add a small pinch of nutmeg as well. - Raisin Banana Oatmeal Cookies
Replace the chocolate chips with 1 cup raisins. This creates a more traditional oatmeal-cookie flavor while keeping the banana and peanut butter combination. - White Chocolate Banana Cookies
Use white chocolate chips instead of regular chocolate chips for a sweet and creamy variation. - Peanut Butter and Jelly Cookies
Add a small spoonful of strawberry or grape jam to the center of each portion of dough before baking for a peanut butter-and-jelly-inspired treat. - Triple Chocolate Cookies
Combine semisweet chocolate chips, milk chocolate chips, and white chocolate chips for a rich cookie packed with different chocolate flavors. - Honey Banana Oatmeal Cookies
Replace a portion of the granulated sugar with honey. The honey adds extra sweetness and complements the natural flavor of ripe bananas. - Breakfast-Style Banana Cookies
Add chopped nuts, raisins, and a little cinnamon while reducing the chocolate chips. These make a hearty cookie that works well as a grab-and-go snack. - Extra Reese’s Cookies
Increase the amount of Reese’s Baking Cups and Pieces and press additional pieces onto the tops immediately after baking for a more indulgent peanut butter finish.
FAQs
1. Can I use frozen bananas?
Yes. Thaw the bananas completely and drain away excess liquid before mashing them and adding them to the dough.
2. What type of oats should I use?
Quick oats work best because they create a soft and chewy texture. Old-fashioned oats can be used, but they will give the cookies a heartier texture.
3. Can I use crunchy peanut butter?
Yes. Crunchy peanut butter works well and adds small pieces of peanuts throughout the cookies.
4. Can I make these cookies without Reese’s pieces?
Absolutely. You can replace them with additional chocolate chips, peanut butter chips, chopped peanuts, or another favorite candy.
5. Why are my cookies too soft?
The banana adds considerable moisture. Allow the cookies to cool completely before judging their final texture, as they firm up as they cool.
6. Can I make the cookie dough ahead of time?
Yes. Cover the dough tightly and refrigerate it for up to 24 hours. Let it sit briefly at room temperature if it becomes too firm to scoop.
7. Can I freeze these cookies?
Yes. Once completely cooled, place them in a freezer-safe container or bag and freeze for up to 3 months.
8. How do I keep the cookies soft?
Store them in a tightly sealed container. Adding a small piece of bread to the container can also help maintain softness.
9. Can I use whole wheat flour?
You can replace part of the all-purpose flour with whole wheat flour, although the cookies may be slightly denser and more hearty.
10. How do I know when the cookies are done?
The edges should be lightly browned while the centers may still look slightly soft. They will continue to set as they cool on the baking sheet.
Peanut Butter Banana Oatmeal Cookies are a delicious combination of ripe bananas, creamy peanut butter, chewy oats, chocolate chips, and Reese’s pieces. They come together quickly and make a great homemade snack or dessert, especially when you have ripe bananas ready to use.
