Time goes by way too fast. I remember when my friend asked me earlier this year to make cupcakes for her wedding in August I felt like I had plenty of time to test and experiment. Uhhh…how is it July already?! I am super excited for August though, it will be a busy baking month. I will be baking cupcakes for two weddings and a bridal shower. Good thing I got started early on one of the weddings. I also have some fun ideas for the bridal shower too.

For the first wedding in August, the theme will be “loose item/book”. My friend sent me some ideas and one of them was Harry Potter butter beer cupcakes! I love Harry Potter and I still remember how delicious butter beer tasted from my trip to Harry Potter land so I immediately said yes! I ordered those adorable Harry Potter cupcake liners and lighting bold sprinkles. I am so excited to test these butter beer cupcakes out. I couldn’t test these out this weekend cause I still needed to gather some ingredients.

The other flavour she requested was blueberry or anything that will work with her wedding colour purple. I did some research and decided to test out these lemon blueberry cupcake. I also saw these adorable heart shaped cupcake toppers made from pages of a book on Pinterest and thought it will go perfectly with her book theme!

These were so good I made a second batch!

These cupcakes turned out super moist! Usually butter-based cupcakes are less moist than oil-based cupcakes. But because of the addition of milk, sour cream, and also fresh blueberries – these cupcakes have the buttery flavour and perfect amount of moisture. The lemon flavour from the zest also perfectly compliments the fresh blueberries. I converted cups to grams and measured flour, butter, and sugar with a scale to ensure accuracy.

I had trouble finding a good blueberry buttercream. I tried to avoid recipes using blueberry jam because it adds extra sweetness. Other blueberry buttercream recipes uses freeze dried blueberries which is impossible to find in Toronto (Wish we had Trader Joes >_<). I finally found a recipe using homemade blueberry syrup. I was worried it might make the buttercream too runny but it turned out perfect and the colour was the colour I hoped for too! The only downside is the blueberry flavour in the buttercream is very subtle. If you add too much syrup, the buttercream will become too runny – its all about balance!

 

I loved these cupcakes so much I made two batches already! The first batch was consumed at a friend’s birthday party and the other batch will be for our own enjoyment and shared with coworkers and more friends! Yay!
