To sweeten the strawberries, take the 2 1/2 cups of strawberries and put them in a bowl. Mix them with the 2 tbsp of honey and the juice of one lemon. Cover and place in the fridge for at least two hours, or overnight.
Preheat the oven to 350 F. Grease a spring form cake pan.
Crack two eggs in a bowl and beat. Add in the honey, rum extract, vanilla extract and melted butter and stir well.
Add in the spelt flour, the white flour, the baking powder, and the salt. Stir until completely mixed.
Add in the strawberry mixture. Fold into the batter just until mixed. Do not overmix.
Bake for 50-60 minutes depending on your oven. It is done when you can insert a toothpick in the cake and it comes out clean.
