Ingredients -
3 Cups Chocolate Chips (your choice, I used semi-sweet)
1 14oz can Sweetened Condensed Milk
1/4 cup butter
1 cup chopped nuts (optional)
1 gram concentrate
Preheat oven to 275F. Melt butter in microwave safe bowl and set aside. Put chocolate chips and condensed milk in microwave safe bowl and microwave on medium heat for 5 minutes or until melted (Stir once or twice to smooth mixture while cooking.) While the chocolate mixture is cooking, start decarboxylating the concentrate on parchment paper in oven for approx 5 minutes or until bubbles stop. Quickly add the decarboxylated concentrate to the melted butter and wisk to blend properly. Add butter to fudge right after it finishes in the microwave then stir well to combine. Pour fudge into greased 8x8 pan and put in the fridge to set.
When cooled, cut into 2x2 squares for approx 16x 50mg doses (assuming your infused butter was roughly 750mg THC)
