Keto Pumpkin Spice Latte (Sugar-Free PSL)
All the cozy pumpkin spice flavor without the 40g sugar hit. This sugar-free PSL uses a homemade allulose pumpkin spice syrup with real pumpkin purée, All Jacked Up Espresso, and unsweetened almond milk — about 3–4g net carbs per serving.
PSL Without the Sugar Crash.
- A standard coffeehouse PSL has 40g+ of sugar — this version has approximately 3–4g net carbs
- Allulose in the syrup dissolves smoothly and behaves like sugar without spiking blood glucose
- Real pumpkin purée keeps the flavor grounded and adds trace fiber rather than empty sweetness
- Works hot or iced — same syrup, same espresso base
Why allulose works in this recipe:
- Minimal glycemic impact — clinical research shows allulose can blunt post-meal glucose and insulin rises when consumed with carbohydrates
- Very low calorie — the FDA lists approximately 0.4 kcal per gram and excludes it from total and added sugars on nutrition labels
- No gritty texture — unlike erythritol, allulose dissolves completely in hot and cold liquids and produces a smooth, glossy syrup without aftertaste
What You'll Need
Sugar-Free Pumpkin Spice Syrup (keeps 1 week in fridge):
- ½ cup water
- ⅓ cup pumpkin purée
- ½ cup allulose or monk fruit blend
- 1 tsp pumpkin pie spice
- ½ tsp vanilla extract
For the Latte:
- 8 oz strong brewed All Jacked Up Espresso or double shot espresso
- ¾ cup unsweetened almond milk (or almond milk + 2–3 Tbsp heavy cream for keto fat boost)
- 2 Tbsp sugar-free pumpkin spice syrup
- Sugar-free whipped cream, optional
- Ground cinnamon or nutmeg, for garnish
5-Minute Shortcut:
Warm ½ cup pre-made allulose syrup with 2 Tbsp pumpkin purée, 1 tsp pumpkin pie spice, and ½ tsp vanilla. Stir until smooth — no simmering required. Same result in half the time.
How To Make It
Make the Sugar-Free Pumpkin Spice Syrup:
- Whisk water, pumpkin purée, and allulose together in a small saucepan over medium heat.
- Simmer until smooth and slightly thickened — about 3–5 minutes. Stir in pumpkin pie spice and vanilla.
- Cool completely and refrigerate for up to 1 week.
Assemble the Latte:
- Brew 8 oz All Jacked Up Espresso strong or pull a double shot.
- Heat almond milk (or almond milk and cream blend) until steaming. Froth until foamy.
- Stir 2 Tbsp sugar-free pumpkin spice syrup into the hot coffee.
- Pour frothed milk over the coffee. Top with sugar-free whipped cream and a dusting of cinnamon or nutmeg.

A coffeehouse PSL habit at 40g of sugar per drink adds up fast. This version gives you everything that makes the drink worth ordering — real pumpkin, warm spice, bold espresso, frothed milk — at about 3–4g net carbs. Make the syrup once and it's in your fridge all week.
Frequently Asked Questions
How many carbs are in a keto pumpkin spice latte?
This sugar-free PSL comes in at approximately 3–4g net carbs per serving — mainly from trace amounts in the pumpkin purée and spices. The allulose sweetener has minimal glycemic impact and is excluded from total added sugars on nutrition labels. Compare that to a standard coffeehouse PSL at 40g+ of sugar per Grande serving.
Can diabetics drink pumpkin spice lattes?
A standard coffeehouse PSL is very high in sugar and would significantly spike blood glucose for most people with diabetes. This homemade sugar-free version uses allulose instead of sugar — allulose has shown minimal impact on blood glucose and insulin in clinical research. As with any dietary change, people managing diabetes should check with their healthcare provider about specific sweeteners and portion sizes for their individual situation.
What is the best sugar substitute for pumpkin spice syrup?
Allulose is the best choice for coffee syrups specifically — it dissolves smoothly, produces a glossy result, and has no cooling aftertaste or grittiness. Monk fruit blend is a close second and easier to find in some areas. Erythritol works but can leave a cooling sensation and doesn't dissolve as cleanly in liquids. Avoid stevia-only sweeteners in syrups as the aftertaste becomes more pronounced when concentrated through cooking.
Can I use heavy cream instead of almond milk?
Yes — a blend of unsweetened almond milk and 2–3 Tbsp heavy cream gives you richer texture, higher fat macros for keto, and keeps carbs extremely low. Heavy cream on its own is too thick to froth well as a latte milk — the almond milk blend froths better and produces a more latte-like result while still delivering the fat content keto requires.
