Cook bacon: Heat a large nonstick skillet over medium. Add bacon; cook, stirring occasionally, until browned and crisp, about 8 minutes. Remove from heat. Using a slotted spoon, transfer bacon to a paper towel-lined plate.
Combine cream cheese and mayonnaise: Stir together mayonnaise and cream cheese in a medium bowl until fully combined.
Add remaining ingredients: Fold in bacon, Cheddar, almonds, and scallions. Serve immediately, or cover and refrigerate up to 3 days.
