How to Make 3-Ingredient No-Bake Butterscotch Cookies

Step 1: Prepare the Baking Sheet

Line a large baking sheet with parchment paper or wax paper.

Set it aside.

Step 2: Melt the Butterscotch

Place the butterscotch chips and peanut butter in a microwave-safe bowl.

Microwave in 20-second intervals, stirring well after each interval.

Continue until completely smooth.

You can also melt the mixture in a saucepan over very low heat.

Step 3: Add the Cereal

Pour the crispy cereal into the melted butterscotch mixture.

Gently fold until every piece is evenly coated.

Try not to crush the cereal too much.

Step 4: Scoop the Cookies

Use a spoon or small cookie scoop to drop mounds of the mixture onto the prepared baking sheet.

Work fairly quickly because the butterscotch will begin to firm as it cools.

Step 5: Shape

Use the back of a spoon to gently shape each mound into a cookie.

You can leave them rustic or flatten them slightly.

Step 6: Let Them Set

Allow the cookies to sit at room temperature for about 20–30 minutes, or until firm.

For faster setting, refrigerate them for 10–15 minutes.

The Secret to Perfect No-Bake Butterscotch Cookies

The most important thing is to melt the butterscotch slowly.

Butterscotch chips can become thick or grainy if overheated.

Use short microwave intervals and stir frequently.

The peanut butter helps keep the melted mixture smooth and easier to coat over the cereal.

Best Cereal to Use

Several cereals work well.

Crispy Rice Cereal

Light and crunchy.

Cornflakes

Creates a more textured, classic no-bake cookie.

Rice Squares

Adds extra crunch.

Chow Mein Noodles

For a haystack-style version, replace the cereal with crispy chow mein noodles.

Butterscotch Cornflake Cookies

Use 4 cups cornflakes instead of crispy rice cereal.

Fold them gently into the melted butterscotch-peanut butter mixture.

Drop into mounds and allow them to set.

This version has a crispier, chunkier texture.

Butterscotch Haystack Cookies

Replace the cereal with approximately 4 cups crispy chow mein noodles.

Coat them in the butterscotch mixture.

Drop spoonfuls onto parchment.

Let set until firm.

Chocolate Butterscotch Cookies

For extra chocolate flavor, drizzle the cooled cookies with melted semisweet chocolate.

You can also stir in a small handful of chocolate chips after the mixture has cooled slightly.

Peanut Butterscotch Cookies

For stronger peanut flavor, increase the peanut butter to 1¼ cups.

You can also sprinkle chopped roasted peanuts over the tops before the cookies set.

Salted Butterscotch Cookies

Sprinkle each cookie with a tiny pinch of flaky sea salt.

This helps balance the sweetness of the butterscotch.

Holiday Butterscotch Cookies

Before the cookies set, decorate with:

• Red and green sprinkles
• Mini chocolate chips
• Chopped peanuts
• White chocolate drizzle
• Holiday sanding sugar

These make an easy addition to Christmas dessert trays.

Can I Make Them Without Peanut Butter?

Yes.

You can substitute:

• Almond butter
• Sunflower seed butter
• Cashew butter

The flavor and texture will change slightly.

Make-Ahead Instructions

These cookies are perfect for making ahead.

Prepare them completely and allow them to set.

Store them in an airtight container with parchment between the layers.

They’re great for preparing a day or two before parties or holidays.

Storage

Store at room temperature in an airtight container for approximately 4–5 days.

If your kitchen is very warm, refrigerate them to keep them firm.

Allow refrigerated cookies to sit at room temperature briefly before serving if you prefer a softer texture.

Can You Freeze No-Bake Butterscotch Cookies?

Yes.

Place the cookies in a freezer-safe container with parchment paper between layers.

Freeze for up to approximately 2 months.

Thaw at room temperature before serving.

Absolutely.

They may need more setting time or slightly more cereal.

Pro Tips

Measure all three ingredients before you begin because the mixture starts setting fairly quickly once the butterscotch cools.

Melt the butterscotch gently and avoid overheating. For the best texture, fold the cereal carefully so it stays crunchy.

For an extra-finished look, add a semisweet chocolate drizzle and a tiny pinch of flaky sea salt after the cookies have set.
