Preheat the oven to 350 F (177 C). Generously grease a 12 count muffin pan with smooth muffin cup wells.
Place pitted and chopped dates into a medium bowl. Top the dates with baking soda. Gently toss the dates to cover with baking soda. Pour boiling water over the dates, cover with a tea towel and allow the dates to soak for about 15 minutes.
1 cup pitted and chopped dates, 1 teaspoon baking soda, 1 cup (240 ml) boiling water
Pour the date mixture into a stand mixer fitted with paddle attachment or blender. Mix the dates and water together until a loose paste forms.For a smoother date paste pour the dates and milk into a blender or food processor. Once the paste is created, return the date paste back to the same bowl used to soak the dates in and set aside for now. Wipe the mixing bowl to remove any significant date paste residue.
In a large bowl, whisk together the flour, baking powder, cinnamon and salt together until well combined. Set aside for now.
1¾ cup (210 g) all purpose flour, 1½ teaspoons baking powder, 1 teaspoon ground cinnamon , ¼ teaspoon salt
In a large mixing bowl fitted with paddle attachment, cream the butter and light brown sugar together on medium speed for 3 - 4 minutes until well combined.
½ cup (113 g) unsalted butter, room temperature, ¾ cup (150 g) light brown sugar
With the mixer on low, cream in the eggs, vanilla extract and molasses, followed by the date paste. Once the date paste, eggs, vanilla extract and molasses are fully mixed in, increase the mixer speed to medium for another minute. Scrape the bottom and sides of the bowl as needed. With the mixer on low, mix in the dry ingredients into the wet until just combined.
2 large eggs, room temperature, 2 teapsoons (10 ml) vanilla extract , 2 tablespoons (30 ml) molasses
Evenly pour the sticky toffee cake batter into the prepared muffin pan. Bake the mini toffee cakes for 20 -25 minutes or until a toothpick inserted into the center of the cake comes out clean or with a few moist crumbs. The crust will be golden brown and the top should bounce back when gently pressed. Cool the cakes in the pan for 10 minutes. Gently remove the cakes and place the top of the mini date cakes upside down on the cooling rack. While the cake cools, make the toffee sauce.
Add the slices of butter, heavy cream and brown sugar to a saucepan. Heat the mixture to a boil over medium-high heat. Stir and simmer the mixture for about 2-3 minutes. Remove the pan from the heat, stir in the salt and vanilla extract. The sauce will thicken a bit while it cools. 4 tablespoons (57 g) unsalted butter, cubed, ? cup (160 ml) heavy cream, ½ cup (100 g) light brown sugar, 2 teaspoons (10 ml) vanilla extract , ¼ teaspoon salt
Transfer the cakes to a serving plate or onto individual serving plates, top with toffee sauce and chopped nuts if you like. Serve the sticky date cakes warm with more toffee sauce and ice cream.
