Brew your strong coffee/espresso. I used Café Bustelo k-cup to brew mine.
In a shallow dish, add in the brewed coffee, coffee liqueur, and creamer. Stir to combine and set aside.
In a medium bowl, add in the macarpone cheese, Truvia, and vanilla bean paste. If you don't have vanilla bean paste, substitute with 2 tsp. vanilla extract. Mix to combine thoroughly with a spatula.
Add the light whipped topping in with the mascarpone cheese mixture. Fold using the same spatula until combined.
Set out your 11x7 pan.
Dip and roll each lady finger in the coffee mixture. I let mine soak it up for a second. Place in a lady side by side in the bottom of a pan. It should be 2 rows of 4. Place one whole lady finger and a half in the very end to fill in the empty spot.
Add half of the mascarpone cheese mixture and spread to cover all of the lady fingers.
Repeat the dipping and placing of the lady fingers on the next layer.
Add the remaining mascarpone mixture on top of the lady fingers and spread to all of the edges.
Cover with plastic wrap and let it set overnight.
Before serving, grate the chocolate bar over the top of the tiramisu. I used a milk chocolate bar, but a bittersweet bar would work well too.
Notes
To store any tiramisu leftovers, store in an air tight container in the refrigerator for up to 3 days.
