Instructions

  1. Preheat the oven to 350°F. Prepare an 8" square pan with a parchment sling or reusable silicone liner, then lightly grease the sides of the pan. Alternatively, line a 9" cake pan with a round piece of parchment or round reusable liner and lightly grease the sides.

  2. To make the filling: In a small bowl, combine the sugar and cocoa. Set aside. 

  3. To make the crumbs: Weigh your flour; or measure it by gently spooning it into a cup, then sweeping off any excess. In a medium bowl, whisk together the flour, sugars, and salt. Add the butter and vanilla; toss to combine. Using a bowl scraper, fork, or your fingertips, work in the butter until no dry spots remain and crumbs form. The crumbs should range in size from peas to walnuts. Stir in the sprinkles; set aside.

  4. To make the cake: In a large bowl or bowl of a stand mixer, combine the flour, sugar, baking powder, salt, and baking soda. Add the butter and mix at low speed until the mixture looks sandy, about 1 to 2 minutes. (This is known as the reverse creaming or paste method.)

  5. Beat in the extracts and eggs, then mix until no dry spots of flour remain. Stop the mixer and scrape the bowl and beater as needed; the mixture will be thick.

  6. Keep the mixer running and slowly add the buttermilk. Mix until smooth, then stop the mixer to scrape the bowl and mix again at medium-low speed for 30 seconds.

  7. Gently fold the sprinkles into the batter. 

  8. To assemble the coffee cake: Transfer half the batter (about 2 cups, 420g) into the prepared pan, spreading it all the way to the edges. 

  9. Sprinkle the filling evenly over the batter.

  10. Pour the remaining batter evenly over the filling and gently spread to the edges (a small offset spatula is a helpful tool here). The top layer will be thin; it’s OK if some filling gets mixed in.

  11. Sprinkle the crumbs evenly over the batter and gently press to help them adhere. 

  12. Bake the cake for 45 to 50 minutes, until it’s set in the middle and light brown on top. When the cake is done, a toothpick or paring knife inserted into the center should come out mostly clean. 

  13. Remove the cake from the oven and allow it to cool in the pan for 20 minutes. While the cake is cooling, prepare the glaze. 

  14. To make the glaze: In a small bowl, stir together the glaze ingredients until smooth, starting with the smaller amount of water. Add additional water as needed until the glaze is the consistency of molasses. 

  15. Remove the cake from the pan. Drizzle the glaze over the cake and garnish with additional sprinkles. Cut and serve warm or at room temperature. 

  16. Storage information: Store leftover Birthday Coffee Cake, well wrapped, at room temperature for several days; freeze for longer storage. 

Tips from our Bakers

  • For easiest handling, cut your butter into cubes while it’s still cold and then let it come to room temperature. Cubing room temperature butter can be messy.

  • Want to make this coffee cake gluten-free? For great results, substitute King Arthur Gluten-Free Measure for Measure Flour for the all-purpose flour in this recipe, and make sure all your other ingredients are gluten-free. When making the crumbs, melt the butter before incorporating it into the dry ingredients. Be sure to bake thoroughly; gluten-free baked goods often need a bit more time in the oven.

  • Substitute 1 cup (227g) plain Greek yogurt for the buttermilk, if desired. Add it to the batter during step 6 (when the buttermilk is called for), but add the yogurt all at once with the mixer turned off and then proceed with the recipe. The batter will be thick; no other changes need to be made.
