Recipe Tips

✔ Use Finely Ground Almond Flour – For the best texture, use blanched, finely ground almond flour rather than almond meal.
✔ Adjust Sweetness to Taste – Some sweeteners are sweeter than sugar, so adjust to your preference.
✔ Check for Doneness – If the center still looks wet, microwave in 10-second intervals until fully set.
✔ Let It Cool Slightly – The cake will be hot right out of the microwave and needs a minute to firm up.
