Set oven to 350°F.

In a bowl add the oil, sugar, and eggs. Whisk together until it becomes thick. Add all of the dry ingredients and whisk together. Add your vanilla extract and milk and do one more whisk to fully incorporate everything and bring it into a nice smooth batter.

In a bowl add the oil, sugar, and eggs. Whisk together until it becomes thick. Add all of the dry ingredients and whisk together. Add your vanilla extract and milk and do one more whisk to fully incorporate everything and bring it into a nice smooth batter. If you wanted to do this with a hand mixer, you could, but I think by hand is best. Grease your 6 inch tin and pour the batter into the tin. Place into the oven and bake for 55 minutes – 1 hour. Insert a toothpick to see that it is fully baked. If not, place back in the oven for 5 minutes and check again. You want a fully baked cake!

Allow it to cool in the cake tin for 5 – 10 minutes then transfer to a wire rack to cool completely. Once completely cooled, slice the cake so that you will have 3 layers. Then make your frosting.

Making the Blue Frosting

In the bowl of a stand mixer ( you can also use a hand mixer if you are desperate) with the beater attachment, add the butter. Allow it to beat for 2 minutes just to lighten up the butter. Add the powdered sugar and make sure your mixer is set to a low speed because the powdered sugar will fly everywhere. Once it is added, your frosting needs to mix for 3-5 minutes for it to fully come together. Add the almond extract, blueberries, and jam. Let the frosting really come together. The blueberries will have a bit of chunk to them but they will break down. Add the blue food coloring. Thus your blue frosting is complete!

Put an even layer of frosting on each layer of cake. The way I like to measure this is by using an ice cream scooper. Use an offset spatula to work the frosting all around the cake layer. If you want it to look like the cake from the film then some needs to be kind of hanging off of the side.

Repeat this step. Add the top layer, cover with frosting and place a pile of blueberries in the middle or cover in candles or however you want to decorate it! You could use a piping bag for your icing if you chose, however, I do not think it is necessary.
