About
Let Them See Cake is one of Cardiff's most creative and colourful bakeries, and we're so proud to be the not-so-secret ingredient in some of their signature bakes including this Birthday Cake Cookie Sandwich! They've been kind enough to share their recipe with us so even if you're not in Cardiff you can give this cookie recipe a spin for yourself!
To make the dough
Cream the softened butter and sugars until light and fluffy, scraping down the bowl a few times.
Add in half of the beaten egg (about 41g) and a few drops or 1/4 teaspoon of vanilla extract.
In a separate bowl, combine all the dry ingredients: plain flour, bicarbonate of soda, funfetti sprinkles, mini white chocolate chips, and white chocolate chips.
Slowly add the dry mix to the butter mixture and mix until just combined.
Now, you have the dough ready for your cookies. To make 30 cookies:
Divide the dough into 30 equal portions.
Roll each portion into a ball.
Place the balls on baking sheets.
Bake at 170°C (130°C on the dial for a large oven) for approximately 6-7 minutes, or until the edges are lightly golden. Be sure to keep an eye on them as they bake and adjust the time if needed.
After the first bake, gently flatten and shape the cookies using a round cutter, if desired.
Bake again for another 5-6 minutes, or until the cookies are fully set but still slightly soft in the center.
Remove from the oven and allow them to cool on a wire rack.
