Coat a 9-by-13-inch baking pan with 2 tsp. coconut oil. In a large bowl, combine oats, flour, sugar, cinnamon and 3/4 tsp. salt. In a medium bowl, combine honey, peanut butter and remaining 1/3 cup coconut oil. Whisk in eggs and vanilla. Stir egg mixture into oat mixture until combined. Spread the batter in the pan; press to compact. Sprinkle with 1/4 tsp. salt. Bake at 350 degrees until golden-brown, about 35 minutes. Let stand 10 minutes; cut into 16 bars. Serve each bar with a container of yogurt. Store remaining bars in an airtight container.
