How to Make 4 Ingredient Confetti Squares
Line the Pan: Begin by lining an 8×8” baking pan with overlapping parchment paper, ensuring you have a sturdy base for easy removal later.
Melt the Base: In a large saucepan, melt the butter and peanut butter together over medium-low heat, stirring gently until smooth and well combined.
Add Butterscotch Chips: Once the mixture is melted, add the butterscotch chips and stir until fully melted and the mixture is glossy, ensuring no lumps remain.
Cool Down: Remove the saucepan from heat and let it cool to near room temperature, stirring occasionally so it doesn’t harden too quickly.
Fold in Marshmallows: Gently fold in the mini marshmallows until all are well-coated with the peanut butter and butterscotch mixture, creating a colorful and fluffy blend.
Transfer Mixture: Pour the mixture into the prepared baking pan and smooth it into an even layer using a spatula or the back of a spoon.
Chill: Cover the pan with plastic wrap and refrigerate for 4-5 hours or until the squares are firm and set.
Slice and Serve: Once firm, remove the squares from the pan using the parchment paper, and slice them into squares to serve.
Optional: Drizzle with melted chocolate for an extra touch of sweetness.

Expert Tips for 4 Ingredient Confetti Squares
Cooling Time: Allow the peanut butter and butterscotch mixture to cool sufficiently before adding marshmallows; this keeps the marshmallows from melting into the mix.
Watch the Heat: Melt butterscotch chips over low heat to prevent burning; if they start to bubble or smoke, lower the heat immediately to save your ingredients.
Proper Chilling: Don’t rush the chilling process; cutting the squares too soon can lead to a gooey mess. Chill for a full 4-5 hours for the best texture.
Even Mixing: Gently fold in the mini marshmallows to ensure they remain fluffy and intact, creating that delightful chewy texture within your 4 Ingredient Confetti Squares.
Fun Variations: Feel free to swap butterscotch chips for semi-sweet chocolate for a delicious twist on the classic recipe; it’s an easy way to introduce new flavors!

4 Ingredient Confetti Squares Recipe FAQs
What type of butter should I use for the squares?
I recommend using unsalted butter for a balanced flavor, allowing the natural sweetness of the butterscotch chips to shine. If you’re dairy-free, consider using margarine or a dairy-free butter substitute, but ensure it melts smoothly.
How should I store my leftover squares?
To keep your 4 Ingredient Confetti Squares fresh, store them in an airtight container in the refrigerator for up to 5-7 days. I often place layers of parchment paper between squares to prevent them from sticking together. This also helps to maintain their chewy texture!
Can I freeze these confetti squares?
Absolutely! For longer storage, wrap the squares tightly in plastic wrap, and then cover with aluminum foil to prevent freezer burn. They’ll keep well for up to 2 months. When you’re ready to enjoy them, simply thaw them in the refrigerator overnight for the best texture.
What if my butterscotch chips aren’t melting smoothly?
If you encounter this, it may be due to overheating. Simply return the saucepan to low heat and stir continuously until fully melted. Remember to keep the heat low and be patient; this helps avoid burning and achieving that velvety consistency.
Are these squares suitable for kids and those with peanut allergies?
While they are a favorite among kids—thanks to the vibrant marshmallows and sweet flavors—they do contain peanut butter. If you’re looking for a nut-free option, try replacing the peanut butter with sunbutter or another seed butter that suits your dietary needs. Always check for allergies related to other ingredients as well!
