To cook in the oven: Follow the instructions exactly and place the oven-safe mug on a baking sheet. Bake at 350° Fahrenheit for 10-15 minutes, or until set.
Eggs are essential when baking with almond flour so if you want to make it without the egg, use all purpose flour,
oat flour, or 1:1 gluten free baking flour (like
Bob's Red Mill) instead.
