Kitchen Guide

What type of pumpkin is best for these bars?

Use canned pumpkin puree (not pumpkin pie filling) for best texture and flavor.

Can I substitute nuts in the bars?

Yes, walnuts or pecans work well to add crunch, or you may omit them if preferred.

How do I prevent the frosting from melting?

Allow the bars to cool completely before spreading the brown sugar cream cheese frosting to prevent melting.

What is the best way to store these bars?

Store bars in an airtight container in the refrigerator for up to 5 days to maintain freshness.

Can I make the frosting lighter?

For a lighter frosting, try reducing the butter or substituting part of it with cream, adjusting until you reach desired consistency.

Is there an alternative to vegetable oil in the batter?

Yes, substitute half the oil with unsweetened applesauce for a lighter texture and moisture.
