I made some Blueberry and Cream Cheese Muffins yesterday for my daugher's b'day party - went down a treat. I used fresh blueberries and blueberry jam, but I'm sure you could use the puree.

• 2 1/4 cups self-raising flour, sifted
• 1/2 cup caster sugar
• 100g butter, melted, cooled
• 1 cup milk
• 2 eggs, lightly whisked
• 1 teaspoon vanilla extract
• 150g fresh or frozen blueberries
• 60g cream cheese, cut into 12 cubes
• 1 1/2 tablespoons blueberry jam
Method
1. Preheat oven to 200?C. Lightly grease a 12-hole 1/2-cup capacity muffin pan.
2. Combine flour and sugar in a bowl. Make a well in the centre.
3. Whisk butter, milk, egg and vanilla in a jug. Pour into well. Add blueberries and gently fold until just combined. Half fill muffin holes with mixture. Top each muffin with a cream cheese cube and 1/2 teaspoon jam and cover with remaining mixture.
4. Bake muffins for 15 to 20 minutes or until a skewer inserted into the top half of muffins comes out clean. Stand in pan for 5 minutes. Turn muffins onto a wire rack to cool slightly. Serve warm.
Makes 12

How about folding it through some icecream? Or yoghurt?
