Preheat oven to 350°F. Line a baking sheet with parchment paper (or tinfoil if you’ve run out). Set aside.
Combine the flour and the egg in a large bowl. Add the peanut butter, water, and honey, and stir until you have a stiff dough. Don’t be alarmed if the dough feels very firm – this is normal! You may have to use your hands. On the other hand, if the dough is too wet or sticky, it may be because your peanut butter brand is more oily than the one I used. Add 1-2 tbsp flour until you get a pliable dough.
On a lightly floured surface, roll out the dough about ½-inch thick and use a cookie cutter (or wine glass like I did) to make shapes.
Bake for 18-20 minutes, until golden. Once done, set aside to cool. Watch out for smaller biscuits as these will bake faster and you don’t want them to burn.
To make the frosting, combine the peanut butter and honey in a microwavable bowl. Stir the mixture every 15 seconds until it’s completely melted. If you don’t have a microwave, you can use a saucepan on a low heat.
Drizzle the frosting over the biscuits.
Store in an airtight container.
