Keto Lemon and Poppyseed Muffins with Lemon Cream Cheese Frosting

Keto Lemon and Poppyseed Muffins with Lemon Cream Cheese Frosting

The vibrancy and sourness of lemon makes my mouth water! Keto Lemon and Poppyseed muffins celebrates that tangy freshness of lemon in the best way possible, and topped with Lemon Cream Cheese frosting are a beautiful dessert for a special occasion.

In this recipe I use xylitol, which I buy from Iherb (link here). I’ve written an article on why I have chosen Xylitol as my sweetener of choice for those interested.

To get the xylitol really fine, I use a food processor to blitz it a few times until it is a fine powder. This works perfectly for dusting, like in my Keto Raspberry Tarts and it helps the xylitol dissolve faster. You could also use a coffee or spice grinder to do this, or buy the confectioners xylitol which is already really fine.

I also recommend using blanched almond flour as it is much finer than the almond meal you can buy in the supermarkets. I buy Bob’s Red Mill Almond Flour or buy it from local specialty stores if I am after a few other things.
