My dad is so predictable. Every year he wants me to make him the same thing for his birthday. Actually, come to think of it, he requests the same dessert for any holiday, weekend, special occasion I can think of: Cinnamons Rolls. Where doughnuts are my weakness, my dad’s kryptonite is a warm, freshly baked cinnamon roll smothered with cream cheese. However, this year I wanted to make him a proper birthday cake. I made him a walnut banana rum cake with cinnamon cream cheese icing and white chocolate numbers. This week my family celebrated my dad’s 70th birthday! (Yes, if you do the math, my dad was in his 40s when I was born.) As a kid, I used to complain that my dad was a lot older than the other kids’ parents, but at this age, I’m super thankful. Throughout my life, my dad has always been a great source of wisdom. He has experienced so much life before having kids that he knows the answer to pretty much any question I ask him. (Think about it: he was in his late 20s-mid 30s living in Los Angeles during the 1960s and 70s. You bet he has stories to tell…) My dad is a constant source of inspiration. He embodies everything I want to be like when I get older. He is always changing for the better. Whether its eating healthier or being open to trying new things, he is always working on becoming a better person. My dad is the greatest man I know. (If I ever got to meet my grandfather, I’m sure I would understand where he gets it from.) The older I get, the more I appreciate and value him. With each year, he seems to get happier and happier. He smiles more, laughs louder, and gives back more than ever. I’ve always feared getting older. The idea of wrinkles and white hairs throws me into a frenzy. (I get slightly offended when I am not carded for a drink, even if I turned 21 almost eight years ago.) But seeing how much fun my parents are having, growing old seems like something to look forward to. So this banana cake has everything you could ever want in a birthday cake…sugar, booze, and sprinkles. It’s a festive approach to traditional banana bread. I’m really loving the “naked cake” look right now, so I left the sides of the cake bare. To me, it makes the cake look more appetizing and inviting. Frosted cake look so perfect that I often feel guilty slicing into it and messing it up. Instead of a boring cream cheese frosting, I added a little ground cinnamon and splash of rum to liven it up. If this cake was for myself, I would have gone for pink sprinkles. To make the cake a tad more classy for my dad, I used these gold sugar sprinkles. Not only are the sprinkles pretty, they provide a nice crunch to an otherwise soft cake. I found this number lollipop mold during my travels in Italy last summer. You can purchase the same mold here. I love it! Not only is it great for melted chocolate, but you can also use to freeze ice numbers or bake little number cakes. I melted about 3 Tbsp of chopped white chocolate. Any type of chocolate will do, you can also use these white candy melts (from Wilton). Once the chocolate is melted and smooth, transfer it to a small piping bag. I like to make small paper cone piping bags using parchment paper. Here’s a quick video tutorial for the paper cone piping bag. Slip lollipop stick in desired number mold. Then fill numbers with melted chocolate. Fill cavity all the way. Don’t worry if excess chocolate spills over the edges. Use a mini offset spatula to level the melted chocolate with the mold. Let chocolate sit at room temperature until chocolate is solid. Gently pop out chocolate numbers. A birthday isn’t a birthday without cake. But it’s not a party or celebration unless you have more than one dessert. I couldn’t leave my dad hanging on his birthday. Of course I made him the batch of cinnamon rolls he asked for. Recipe coming soon…however, if you are in dire need of cinnamon rolls asap, check out my banana cinnamon rolls.
