a café bombón is a small coffee made with espresso and sweetened condensed milk. it is sweet, so think of it as a short dessert coffee, not a regular mug with some milk added. the classic presentation has a pale layer at the bottom and espresso on top. you can make that in a small glass, then stir before drinking.
start with one shot of espresso and about the same volume of sweetened condensed milk. for a shot around 30 milliliters, that means about 30 milliliters of condensed milk. if you don't like very sweet drinks, start with less. the equal-parts version is a reference point, not a requirement to finish the whole glass if it's sweeter than you expected.
put the condensed milk into the bottom of a small, heat-safe glass. pull the espresso separately. pour it slowly onto the back of a spoon just above the condensed milk. the spoon softens the pour and helps keep the two layers apart. if you pour the espresso straight in quickly, it will mix sooner. nothing is ruined if it does. the glass just won't have the same layered look.
serve it with a spoon. the bottom is very sweet and the top is coffee, so stir them together before taking more than a small taste. you can also use strong moka-pot coffee if that's what you have. it won't be an espresso shot, but it will make a small, concentrated drink with condensed milk. avoid using a full cup of regular drip coffee for the same amount of condensed milk; the drink gets large and thin instead of small and rich.
don't confuse sweetened condensed milk with evaporated milk. condensed milk is thick and sweet; evaporated milk is not the same ingredient and won't give you the same sweetness or layering. check the can before opening it. if you have leftovers, move them to a clean covered container and follow the package directions for storage rather than leaving the open can on the counter.
if you like the flavor but find the equal-parts version too sweet, use less condensed milk next time. if you want to serve it over ice, mix the coffee and condensed milk first, then pour that over ice. that version won't hold the neat hot layers, but it is easier to get an even taste from the first sip.
i'd make the plain version once before adding cinnamon, cocoa, or anything else. it only needs two ingredients. the point is the contrast between strong coffee and sweet milk, and you can decide the balance after you try it.
Couplet has coffee if you want to make one at home.
