To a small saucepan, add in the raspberries, sugar, water, and cake batter extract. Stir occasionally and let the mixture come to a simmer. Let the mixture simmer for 5 minutes, crushing the raspberries as they soften.
Remove the mixture from the heat and pour it through a fine mesh sieve into another bowl or container.
Pink Velvet Macchiato
Start by pouring 2 tbsp. of the raspberry syrup into your cup.
Add in the milk, then mix the milk and raspberry syrup together.
Add in ice, leaving room at the top for the espresso.
Add the cocoa powder to a small espresso cup. Brew your espresso over the cocoa, mixing it together so the cocoa dissolves.
Pour the espresso over the raspberry milk, then serve and enjoy!
Notes
Type of espresso:
I of course used chocolate raspberry espresso, but any mocha, chocolate, raspberry, or plain espresso will work here. You can also use instant espresso, just mix 2 oz. of hot water with the amount of instant espresso required for that that's stated on the packaging, and the cocoa.
If you'd like a less sweet drink:
There are two ways you could go about this - 1. Add less raspberry syrup to your drink. Just note with this that the milk will appear less pink, so you may want to add a bit of pink food coloring to the milk *if* you want a more vivid pink color. 2. Add less sugar to the syrup: there's quite a bit of sugar in the syrup as that's the nature of syrups and raspberries can be quite tart. You can reduce the sugar by up to 50% in the syrup, just taste the syrup as you go to add more sugar if your raspberries are more tart.
Storing extra syrup:
The syrup recipe makes enough for at least 5 drinks. You can store extra raspberry syrup in an airtight container in the fridge for up to one week.
