First mix 1 block of softened cream cheese in a bowl with 1c of sour cream. I recommend using hand mixer so it's very well meshed and fluffy
Add in the spices. 2 tbsp chili powder, 1-2 tbsp garlic powder, 1-2 tsp cumin, 1-2 tsp salt, 2 tsp paprika. When a recipe involves spices, Sometimes I don't give exact measurements because I play around with it and see what I like personally. That's how you become a better cook!
Mix all of the spices in, and put it in the fridge to rest for 1-4 hours. It helps everything infuse together.
Once the mixture has rested, add 3/4 can of chopped black olives and 1/2-3/4c shredded cheddar. Fold them into the mixture.
Spread a decent layer of the mixture on a soft tortilla and roll it up into a roll.
Cut into bite size pinwheel slices and voila!!
