1 cup softened butter + 1 tbsp butter
1 1/2 cups brown sugar
1/2 cup sugar
3 tsp vanilla extract
2 1/2 cups rolled oats
2 1/4 cups all-purpose flour
1 tsp baking soda
2 tsp salt
1/2 tsp cinnamon
2 cups semisweet chocolate chips
1 15 oz. can sweetened condensed milk
Beat together butter and both sugars until fluffy and add eggs, one at a time, until fully incorporated. Add vanilla at this point (I omitted this step as I did not have any).
A personal note: as much as I find a pinch of salt irresistible and necessary in desserts, I thought the fudge was a touch salty. I asked a few people what they thought and it didn't seem to bother them, but maybe they were just being polite. I am a salt girl, really, so you may want to go easy and taste before adding in the whole tsp. Then again, I skipped the vanilla step, so that may have made the difference.
