In a medium bowl, use a hand mixer to combine the cream cheese, sour cream, and mayo until completely smooth.
Shred the Gouda cheese and add it to the bowl. Mix in the cheese, half of the bacon bits, garlic powder, salt, and pepper by hand with a spoon or silicone spatula until combined.
Top with the remaining bacon bits and sliced green onions (optional).
Chill for about 30 minutes before serving to let the flavors intensify. You can chill longer for a firmer cheese spread consistency.
Notes
Gouda tips: If the Gouda comes in wax, remove it and discard. Cut away the rind with a knife before shredding the cheese. Cold cheese is easier to grate.Storage: To store leftover Gouda dip, transfer it into an airtight container. Keep the container tightly sealed and store it in the refrigerator for 3-4 days. This dip can be frozen but the texture may change slightly.Dip vs. Spread: Serve the dip chilled for a firmer texture with a spreader knife or bring the dip to room temperature before serving for a softer dip.
