What are Peanut Butter Squares made of?

The cereal base is made of the following ingredients:

• Brown Sugar
• Corn Syrup
• Smooth Peanut Butter
• Rice Krispies
• Cornflakes
• Vanilla Extract

The icing on top consists of:

• Brown Sugar
• Butter or margarine
• Cream or milk
• Icing sugar

Peanut Butter Squares

Let’s start with the cereal base.

Heat 1/2 cup each corn syrup and brown sugar in a medium saucepan, stirring until sugar is dissolved. Remove from heat. Stir in peanut butter and vanilla extract until smooth.

Add 2 cups each of crushed cornflakes and rice cereal. Stir to coat well. Press into greased 9 x 9-inch or 8 x 8-inch pan.

Brown Sugar Icing

Now for the rich and irresistible brown sugar icing. I have another version of brown sugar icing for my spiced Elvis Presley Cake. It is one of my favourite icings, next to cream cheese frosting.

Measure 1 cup brown sugar, 2 tablespoons butter or margarine, and 4-6 teaspoons cream into a small saucepan. Bring to a boil and allow to boil for 1 minute. Cool. I found 6 teaspoons which equals 2 tablespoons was the perfect amount for mine.

Slowly add about 1 cup of icing sugar to thicken. Beat with a spoon, adding more icing sugar or cream if necessary to get a proper spreading consistency. Spread over the top of the cereal base. Cuts into 16-36 squares.

And that’s it! No baking is required! You will fall in love with these sweet, crunchy, chewy Peanut Butter Squares that are loaded with peanut butter and brown sugar flavour.
