My 40-weight coffee
1 cup of your favorite coffee
2 Tbs.unsalted Kerrygold butter
2Tbs. MCT OIL, fractionated coconut oil or unrefined coconut oil
2 Tbs. heavy whipping cream
10 drops liquid stevia, your choice of flavors (optional)

I use an immersion blender to mix this into a froth but you could use a blender, a frother or a whisk, or just shake it in a jar.

Stevia flavor combos ......5 drops each hazelnut and dark chocolate.............5 drops each vanilla and hazelnut........5 drops each chocolate and vanilla

Other versions of this are called Buller Proof Coffee.
