Cookies 'n' Cream Muffins with Homemade Marshmallow Fluff Icing

I don't think I have met one person who doesn't like oreos; so this recipe will suit everyone! Minus my tweaks, the original recipe was from the 'Primrose Bakery', and is the best cookies n cream cupcake/muffin recipe I have found yet, and it works great with the marshmallow fluff icing! It makes around 18 muffins(use a muffin tin, not a cupcake tin). The Marshmallow Fluff recipe makes a lot, so once you've finished icing, store the remaining fluff in the fridge to eat with toast, or use in cakes, drinks etc.                                                             

Ingredients

Cupcake Mix (the 'Cookie')

115g Dark Chocolate

85g Butter

175g Light Muscavado Sugar

2 Eggs (separated)

185g Plain Flour

3/4tsp Baking Powder

3/4tsp Bicarbonate of Soda

Pinch of Salt

250ml Semi-Skimmed Milk

1tsp Vanilla Extract

Marshmallow Fluff Icing(the 'Cream')

120g Granulated Sugar

80g Golden Syrup

1.5tbsp Water

2 Egg Whites

1/2tsp Vanilla Extract

1 Pack of Oreos 

Method

1. Preheat oven to 190C/fan 170C/gas mark 5. Line a 2 12 hole muffin tins with about 18 muffin cases (if you only have one tin, you can bake them in batches).

2. Melt the chocolate in a heatproof bowl over simmering water, or in the microwave. Leave to cool for about 2 minutes.

3. Cream the butter and sugar in a stand mixer until pale and smooth, then slowly add the egg yolks bit by bit and beat well. Once combined, add the melted chocolate and beat well again.

4. Sift the flour, baking powder, bicarbonate of soda and salt into a medium mixing bowl and mix together until combined. Measure the milk into a jug and stir in the vanilla extract.

5. Gradually add alternate amounts of the dry floury mix and the milk mix into the creamed butter/sugar/chocolate mix, beating well between each addition.

6. In a clean bowl, using a handheld electric whisk, whisk the egg whites until stiff peaks have formed. Then, using a spatula or a metal spoon, fold in the egg whites into the batter until thoroughly combined.

7. Using two spoons, spoon the batter into the cases, filling them about 2/3 of the way up, and bake for around 20 minutes (you'll know if you put the right amount of mix in if it's ready in exactly 20 minutes), or until when you stick a skewer in one, it comes out clean. If you don't have two muffin tins like me, cooking in batches might take a while, so start on the icing once the first batch is done.

8. For the marshmallow fluff icing, put the sugar, golden syrup and water into a pan, and cook on a high heat for about two minutes until the mixture thickens and turns golden (it will resemble caramel).

9. Whisk the egg whites until soft peaks form, then keep beating while slowly adding the hot sugar mixture. Don't worry if your whites lose their stiffness.

10. Continue beating at a higher speed until the mixture becomes thick, glossy and cool. Towards the end, add the vanilla extract. 

11. Wait about 10 minutes for the muffins to cool a bit before adding the icing, then spoon on a small dollop onto each muffin, and smoothen out with a small palette knife, or a round-ended knife.

12. Chop your oreos into quarters, and save the crumbs. Place two quarters on each cake, and sprinkle the remaining crumbs around them. 

And as always, enjoy! :)
