Preheat the oven to 325 degrees F.
Grease and flour two, 8-inch round cake pans and set aside.
Make sure to set the cold ingredients out, so they can come closer to room temperature before making the batter.
In a medium-sized bowl, combine the flour, baking soda, baking powder and salt. Whisk well and set aside.
In another bowl, add the oil, yogurt, milk, vanilla extract, strawberry extract, jam and a couple drops of food coloring. Whisk well and set aside.
In a large mixing bowl, add the room-temperature butter and the sugar and mix with an electric mixer on medium-high for several minutes until light and fluffy.
Add the eggs one at a time, mixing on medium for only about 20 seconds after each.
Scrape down the sides and bottom of the bowl and mix again on medium, only until everything is well incorporated.
Alternately add in the dry mixture and the liquid mixture to the butter mixture, starting and ending with the dry mixture.
Scrape down the sides of the bowl and mix again only for 7-10 seconds or so. The cake batter should be thick and fluffy at this point.
Pour the batter into the two prepared, 8-inch round cake pans, smooth the batter evenly and bake at 325 degrees F on the middle rack for approximately 55-65 minutes. Ovens vary, so start checking at about 50 minutes. A toothpick inserted into the center of each layer will come out with a few moist crumbs on it or clean, but no raw batter. Also note that because they’re baked at 325 degrees F, they will bake up with flat tops.
Remove the cake layers from the oven and place them on a wire rack, still inside the pans, for about 20 minutes. If you try to flip out the cakes earlier, they might stick or fall apart as this cake is very delicate.
After 15 minutes turn the cake layers out of the pans and set them onto the cooling racks and allow them to cool completely before adding filling and frosting.
