Introduction to Peanut Butter
These peanut butter cake mix cookies are a simple way to turn a box of yellow cake mix into a batch of soft, chewy cookies. Creamy peanut butter gives them a familiar peanut flavor, while oil keeps the centers tender and moist.
The dough comes together in one bowl with no chilling required. Scoop it onto lined baking sheets, bake until the edges are set, and let the cookies finish setting as they cool. This recipe makes about 24 cookies, so it works well for a family dessert, bake sale, or casual cookie tray.

Ingredients for Peanut Butter
- 13.25 oz yellow cake mix
- 1 cup creamy peanut butter
- 1/2 cup oil
- 2 large eggs
Use the exact amounts listed: 13.25 oz yellow cake mix, 1 cup creamy peanut butter, 1/2 cup oil, and 2 large eggs. Choose regular creamy peanut butter rather than a natural variety that separates, since a consistent texture makes the dough easier to mix and scoop.
How to Make Peanut Butter
Step 1: Heat the Oven
Set an oven rack in the center position and heat the oven to 350°F. Line two baking sheets with parchment paper. The parchment helps prevent sticking and makes cleanup easier. If you have only one baking sheet, let it cool completely between batches so the dough does not start spreading before it goes into the oven.
Step 2: Combine the Wet Ingredients
Add 1 cup creamy peanut butter, 1/2 cup oil, and 2 large eggs to a large mixing bowl. Stir with a sturdy spoon or beat with an electric mixer on low speed until the mixture looks smooth and evenly combined. Scrape the sides and bottom of the bowl so the peanut butter and eggs are fully incorporated.
Step 3: Add the Cake Mix
Pour in 13.25 oz yellow cake mix. Mix on low speed, or stir by hand, just until no dry cake mix remains. The dough will be thick and soft. Avoid mixing longer than needed, because overmixing can make the cookies less tender and can make scooping more difficult.
Step 4: Scoop the Dough
Scoop the dough into portions of about 1 1/2 tablespoons each and place them on the prepared baking sheets, leaving about 2 inches between portions. If the dough sticks to the scoop, lightly coat the scoop with a little oil from the measured amount before beginning, or use a second spoon to release each portion. Do not add extra ingredients to the dough.
Step 5: Bake the Cookies
Bake at 350°F for 10 to 12 minutes, one sheet at a time if your oven heats unevenly. The edges should look set while the centers still appear slightly soft. Do not wait for the cookies to become deeply browned, because they will continue to firm as they cool. For even baking, rotate the pan halfway through the baking time when needed.
Step 6: Cool and Store
Leave the cookies on the baking sheet for 5 minutes after they come out of the oven. Transfer them to a wire rack to cool completely. Cool the cookies before storing them in an airtight container. Keep them at room temperature for up to 4 days, or freeze them in a sealed freezer-safe container for up to 2 months.
Tips for Success
- Measure the cake mix by using the full 13.25-ounce package called for in the recipe. Different box sizes can change the dough texture.
- Use room-temperature eggs if possible so they blend more evenly with the peanut butter and oil.
- Bake a test cookie first if your oven tends to run hot. Adjust the remaining bake time by a minute if needed.
- For uniform cookies, use a cookie scoop and level each portion before placing it on the baking sheet.
- Let the cookies cool on the pan before moving them. Their centers are delicate while hot and can break if handled too soon.
Equipment Needed
- Large mixing bowl
- Electric mixer or sturdy spoon
- Parchment-lined baking sheets
- Cookie scoop
- Wire cooling rack
Variations
- For smaller cookies, scoop about 1 tablespoon of dough and begin checking them after 8 minutes. The yield will be higher.
- For larger bakery-style cookies, use about 2 tablespoons of dough and add 1 to 2 minutes to the bake time while watching the edges closely.
- For a slightly firmer cookie, bake for the full 12 minutes and allow the cookies to cool completely on the pan before transferring them.
- For a softer cookie, remove the pan when the edges are set but the centers still look noticeably soft, then let the cookies finish setting during the 5-minute rest.
- For a two-pan batch, bake the pans one at a time unless your oven heats both racks evenly. Switching rack positions can change the texture and browning.
Serving Suggestions
Serve these cookies once they have cooled to room temperature and their centers have set. They are easy to pack for a lunch or arrange on a dessert plate with milk, coffee, or tea. For a neat presentation, place the cookies in a single layer or separate layers with parchment paper. Store leftovers in an airtight container at room temperature, and discard them if they develop an unusual odor, visible mold, or a stale texture.
FAQs about Peanut Butter
Can I use natural peanut butter in these cookies? Regular creamy peanut butter is the most reliable choice because it stays blended and gives the dough a consistent texture. Natural peanut butter can separate, so it may make the dough oily or change how the cookies spread.
Do I need to chill the dough? No. The dough is designed to be scooped and baked right away. If your kitchen is very warm and the dough becomes difficult to handle, refrigerate it for 15 to 20 minutes, then scoop and bake as directed.
How do I know when the cookies are done? The edges should look set, while the centers may still look a little soft. They should not be wet or shiny in the middle. The cookies will firm during the 5-minute rest on the baking sheet and while they cool on the rack.
Can I make the cookies with a different cake mix size? The recipe was developed for a 13.25-ounce box of yellow cake mix. A different package size changes the balance of dry and wet ingredients, so use the specified size for the most reliable texture.
How should I freeze these cookies? Cool the cookies completely, then place them in a freezer-safe airtight container with parchment between layers. Freeze for up to 2 months. Thaw them in the container at room temperature so condensation does not collect directly on the cookies.
