This Southwestern avocado dip layers creamy avocado crema with a zesty mix of black beans, sweet corn, and tomatoes. Make it in 25 minutes and tuck in with your favorite tortilla chips.
Blend the base. Combine avocados, sour cream, cumin, chili powder, garlic powder, salt, pepper, and lime juice in a blender; blend until smooth. If it's too thick, add more sour cream and lime juice to thin it out. Taste for seasonings and adjust accordingly.
Combine the mix-ins. In a small mixing bowl, mix the black beans, sweet corn kernels, and chopped tomato.
Layer the dip. In a serving bowl, layer 1/3 of the corn and beans mixture; top with 1/3 of the avocado mixture. Continue to layer, finishing with the bean mixture on top.
Chill and then serve. Garnish with parsley or cilantro. Place in refrigerator for 15 to 30 minutes, or until chilled. Serve with tortilla chips.
