Rainbow Sprinkle Loaf Cake With Birthday Crumb Topping
Sprinkles just make everything better. It's a fact. Case in point: Rainbow Sprinkle Loaf Cake.
Ingredients
Loaf Cake
- 1 cup unsalted butter, room temperature
- 1 ½ cups granulated sugar
- 4 large eggs
- 1 large egg yolk
- 1 tablespoon vanilla extract
- ½ teaspoon kosher salt
- ⅓ cup rainbow sprinkle
Crumb Topping
- ¼ cup all-purpose flour
- ¼ cup granulated sugar
- pinch of kosher salt
- 2 tablespoons unsalted butter, cold
- ⅓ cup rainbow sprinkle
- ½ teaspoon vanilla extract
Instructions
- Preheat oven to 350°. Grease and prepare a 9x5 inch loaf pan.
- In a medium-sized bowl, mix together the flour and salt. Set aside.
- In a large bowl of a stand mixer or using a hand mixture, cream the butter and sugar on a medium speed for 3-4 minutes. Once the butter mixture is fluffy, add in the eggs and egg yolk, one at a time, making sure they are fully incorporated. Scrape down the sides as you go. Stir in the vanilla.
- Next, add the flour mixture to the butter mixture. Keep the mixer on a low speed and slowly pour the flour mixture in. Once the flour mixture is fully combined, stir in sprinkles. Pour the batter into the prepared pan and set aside.
- Make the crumb topping. In a large bowl, combine flour, sugar, and salt. Mix to combine. Using your fingers or a fork, cut in the butter. The crumbs will start to form a sandy-like texture. Once the crumbs start to come together, add in the vanilla and the sprinkles. The crumble should be about pea-sized.
- Add the crumbs on top of the batter of the loaf cake. Don't be afraid if it looks a little overstuffed, they will sink into the top of the batter.
- Bake in the oven for about 65-75 minutes. The top will look golden brown when done. Allow to cool in the pan for 10 minutes. After ten minutes, run a knife around the outside of the pan to remove the cake. Let it sit on a wire rack until completely cool.
