You guys. I made this latte for my 27th birthday as part of my Birthday Cake Bake Series and I am genuinely OBSESSED. It tastes EXACTLY like sipping a slice of birthday cake through a straw. Sweet vanilla, that signature cake batter flavor, a tiny hint of almond, and creamy espresso pulling it all together. It is heaven in a glass and I am not exaggerating.
Here is the thing about this latte. Yes, I made it for my birthday, but you do not need a birthday to drink it. You can drink it on a regular Tuesday and suddenly that Tuesday feels like a celebration. You can drink it on a hard day to feel a little fancy. You can drink it because it is your dog’s birthday, your half birthday, your cat’s adoption-aversary, ANYTHING. Every day deserves a little celebration energy and this latte delivers.
And the BEST part? Making this at home is genuinely cheaper than Starbucks. Like significantly cheaper. I did the math (full breakdown below) and we are talking under a dollar per latte at home versus 6 to 7 bucks at the coffee shop. PLUS you can pronounce every single ingredient, no mystery syrups with 47 ingredients on the back of the bottle. Just real sugar, real extracts, real magic.
P.S. The syrup makes about 10 to 12 lattes worth, so this recipe is the ultimate gift that keeps on giving. Make a batch on Sunday and you have birthday cake lattes ready for the entire week.
Ingredients Needed
Granulated Sugar The base of any good simple syrup. Just plain white sugar here, you want a clean sweetness that lets the cake batter and vanilla flavors shine without competing.
Water Equal parts water and sugar gives you the perfect simple syrup consistency. Not too thick, not too thin, just enough to sweeten and flavor the latte without watering it down.
Cake Batter Extract This is the STAR of the show. It is what makes this taste like birthday cake instead of just vanilla syrup. You can find it at most baking supply stores, on Amazon, or sometimes in the baking aisle next to the vanilla. LorAnn and OliveNation make great ones.
Almond Extract Just an eighth of a teaspoon, but please do not skip it. That tiny amount of almond is what gives the syrup that classic boxed cake mix vibe, it is the secret to authentic birthday cake flavor. More than 1/8 tsp will overpower everything though, so go light.
Vanilla Extract Pure vanilla extract, not imitation. Vanilla rounds out the cake batter and almond flavors and adds that warm, cozy depth that makes you feel like you are biting into a slice of cake.
Milk Use whatever milk you love. Whole milk is the creamiest, oat milk is my fave non-dairy option, almond milk is light and slightly nutty (which actually plays beautifully with the almond extract). Truly your call.
Espresso or Strong Coffee A double shot of espresso is ideal, but if you do not have an espresso machine, super strong brewed coffee or a moka pot shot works perfectly. You want something concentrated so it stands up to all that sweet syrup and creamy milk.
Substitutions and Modifications
- Use any milk you love, whole, oat, almond, soy, coconut, all delicious
- Swap espresso for strong cold brew concentrate for an even smoother iced latte
- Add a pinch of salt to the syrup to make the flavors POP (game changer)
- For a sugar free version, sub the sugar for a 1 to 1 sweetener like allulose or monk fruit
- Top with whipped cream and rainbow sprinkles to make it feel EXTRA birthday
- Add a splash of cold foam on top for the full coffee shop experience\
Why You’ll Love This Recipe

- Costs under a dollar per latte at home versus 6 plus dollars at the coffee shop
- Works iced OR hot so you can drink it year round, summer or winter
Equipment Needed
- Small saucepan for simmering the simple syrup until the sugar fully dissolves.

- Tall glass for serving an iced latte.
- Mug for serving a hot latte.
- Espresso machine, moka pot, or French press for brewing the espresso (or use strong coffee in a pinch).
- Milk frother if you want that pretty foam on top of your hot latte (totally optional).

Homemade Birthday Cake Latte
Ingredients
For the Birthday Cake Syrup
- 1 cup granulated sugar
- 1 cup water
- 1 tsp cake batter extract
- ⅛ tsp almond extract
- 1 tsp vanilla extract
For the Latte (Iced or Hot)
- 1 oz birthday cake syrup
- 6 oz milk of choice
- 2 oz espresso or strong coffee
- Ice for iced version
- Optional toppings: whipped cream cold foam, rainbow sprinkles
Instructions
Make the Birthday Cake Syrup
- Add the granulated sugar and water to a small saucepan over medium heat. Stir to combine.
- Bring to a gentle simmer and let cook for 5 to 10 minutes, stirring occasionally, until the sugar is fully dissolved and the mixture is slightly thickened. You do NOT want it to boil hard, just a steady simmer.
- Remove from heat and let cool for 2 to 3 minutes (you do not want to add the extracts to a roaring hot syrup or the alcohol in them will cook off).
- Stir in the cake batter extract, almond extract, and vanilla extract. Give it a good whisk to combine.
- Let the syrup cool completely to room temperature, then transfer to a glass jar or bottle. Store in the fridge for up to 3 weeks.
Iced Birthday Cake Latte
- Fill a tall glass with ice all the way to the top.
- Add 1 oz of the birthday cake syrup over the ice.
- Pour in 6 oz of cold milk.
- Add the 2 oz espresso shot on top (the layering looks SO pretty).
- Stir well and enjoy! Top with whipped cream and sprinkles if you are feeling extra fancy.
Hot Birthday Cake Latte
- Heat your milk in a small saucepan or in the microwave until warm and steamy. Froth it if you have a frother, this makes it feel SO coffee shop.
- Add 1 oz of the birthday cake syrup to the bottom of your favorite mug.
- Pour in the 2 oz espresso shot and stir to combine with the syrup.
- Top with the warm milk (and the foam if you frothed it).
- Sprinkle a few rainbow sprinkles on top if you want, and sip immediately while it is hot and dreamy.

Storage Instructions
- Counter: The finished latte should be drunk fresh, do not store assembled lattes on the counter.
- Fridge: The birthday cake syrup keeps in an airtight glass jar in the fridge for up to 3 weeks. Give it a good shake before each use.
- Freezer: You can freeze the syrup in ice cube trays for up to 3 months. Each cube is about 1 oz so you can pop one straight into a glass for an iced latte.
Tips and Tricks
- The almond extract is small but MIGHTY. Stick to 1/8 tsp or it will completely overpower the cake batter flavor.
- Let the syrup cool slightly before adding extracts so the alcohol-based flavors do not evaporate off in the steam.
- Use STRONG coffee if you do not have espresso. A double shot of moka pot coffee or super concentrated French press works great.
- A pinch of fine sea salt in the syrup makes the flavors WAY more pronounced. Try it once and you will never make it without.
FAQ
Where do I buy cake batter extract?
Most baking supply stores carry it (think Michaels, Hobby Lobby, Sur La Table) or you can grab it on Amazon. LorAnn Oils and OliveNation are my favorite brands. One bottle lasts forever since you only use a teaspoon at a time.
Can I use vanilla syrup instead of making the cake batter syrup?
You can, but it will not taste like birthday cake, it will just taste like a vanilla latte. The cake batter extract is genuinely what makes this drink unique. Worth the trip to the baking aisle, I promise.
Can I make this caffeine free?
Absolutely! Use decaf espresso or just skip the coffee entirely and make a birthday cake steamer with just the syrup and warm milk. Perfect for kids or for an evening treat.
What if my syrup crystallizes in the fridge?
This sometimes happens if it cooled too quickly or got too thick. Just gently warm it back up in the microwave or on the stove and stir until smooth. It will be totally fine.
Can I double the syrup recipe?
YES, totally. Doubles or triples beautifully. Just keep in mind the syrup keeps for 3 weeks max, so make as much as you will reasonably drink in that timeframe.
Is this drink kid friendly?
The syrup itself is totally kid friendly! Just make a steamer version with warm milk and the syrup (no espresso) and you have a birthday cake hot chocolate situation that kids will go feral for.
