Einkorn Whoopie Pies

Here's the recipe we ended up with for a refined sugar free and cleaner alternative to whoopie pies...

3/4 Cups Einkorn Flour
1 stick melted butter
1 cup coconut sugar
1 cup cocoa powder
4 eggs
1 pinch salt
1/4 cup brewed coffee

Combine and pipe onto a silicone mat. Bake at 350 for 10 to 15 minutes until baked through.

Frosting:
1 stick softened butter
1/2 cup peanut butter
1/4 cup honey (or more to taste)
