What Are Two-Ingredient Peanut Butter Chocolate Cookies?
Two-Ingredient Peanut Butter Chocolate Cookies are soft chocolate cookies made using only chocolate cake mix and peanut butter.
Unlike traditional cookie recipes that require:
- Flour
- Sugar
- Butter
- Eggs
- Baking soda
- Vanilla extract
This recipe relies on the ingredients already included in the cake mix. The peanut butter adds moisture, richness, and structure while creating a deep nutty flavor that pairs perfectly with chocolate.
The result is a cookie that tastes like a cross between:
- A brownie
- A chocolate cookie
- A peanut butter dessert bar
Because the dough comes together quickly, these cookies have become popular among beginner bakers and busy families.
Why This Recipe Works
Many people wonder how only two ingredients can create a delicious cookie.
The answer lies in the composition of chocolate cake mix.
Most cake mixes already contain:
- Flour
- Sugar
- Cocoa powder
- Leavening agents
- Flavoring ingredients
When combined with peanut butter, these components form a workable dough without requiring additional ingredients.
Benefits of this recipe include:
- Minimal preparation
- Budget-friendly ingredients
- Fast baking time
- Beginner-friendly process
- Rich chocolate flavor
- Soft and chewy texture
This simplicity is similar to recipes featured in our Banana Bread Preparation Guide, where a few ingredients create impressive results.
Ingredients Overview
Chocolate Cake Mix
The chocolate cake mix serves as the foundation of the recipe.
Choose a quality chocolate cake mix for the best results.
Popular options include:
- Devil’s Food Cake Mix
- Dark Chocolate Cake Mix
- Triple Chocolate Cake Mix
- Moist Chocolate Cake Mix
Each variety creates slightly different flavors and textures.
Creamy Peanut Butter
Creamy peanut butter provides:
- Fat
- Moisture
- Binding power
- Nutty flavor
Traditional shelf-stable peanut butter works especially well because it creates a consistent dough texture.
Avoid extremely oily natural peanut butter unless it has been thoroughly mixed.
Optional Ingredients
Although the recipe works with only two ingredients, many bakers enjoy adding:
- Mini chocolate chips
- Chopped peanuts
- Sea salt flakes
- Chocolate drizzle
- Peanut butter drizzle
- Crushed pretzels
These additions create more texture and visual appeal.
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to:
350°F (175°C)
Allow the oven to fully reach temperature before baking.
Step 2: Prepare the Baking Sheet
Line a baking sheet with:
- Parchment paper
- Silicone baking mat
This prevents sticking and promotes even baking.
Step 3: Mix the Ingredients
In a large bowl combine:
- 1 box chocolate cake mix
- 1 cup creamy peanut butter
Mix until a thick dough forms.
If the dough appears too dry, add:
- 1 tablespoon milk
- Mix again
- Add a second tablespoon if necessary
Step 4: Portion the Dough
Use a cookie scoop or tablespoon.
Place dough balls onto the prepared baking sheet.
Leave approximately 2 inches between cookies.
Step 5: Flatten Slightly
Use:
- The back of a spoon
- A fork
Press gently to flatten each cookie.
Step 6: Bake
Bake for:
9 to 11 minutes
The cookies should look set around the edges while remaining soft in the center.
Step 7: Cool
Let cookies cool on the baking sheet for:
5 minutes
Then transfer them to a cooling rack.
Step 8: Add Toppings
Once cooled, finish with:
- Chocolate drizzle
- Crushed peanuts
- Sea salt
- Chocolate chips
Serve and enjoy.
Baking Tips for Perfect Cookies
Even simple recipes benefit from a few expert techniques.
Measure Carefully
Too much cake mix can make the dough dry.
Use the entire package as directed.
Avoid Overbaking
The cookies continue cooking after removal from the oven.
Remove them when the centers still appear slightly soft.
Use Fresh Ingredients
Older cake mixes can lose quality over time.
Always check expiration dates before baking.
Let the Cookies Cool
Cooling helps the structure develop fully.
Warm cookies may seem fragile at first.
Use Parchment Paper
Parchment paper helps create even bottoms and easy cleanup.
