This tender blueberry coffee cake topped with a crunchy cinnamon streusel is cleverly named for its habit-forming effect on boys.

This old-fashioned blueberry coffee cake comes with a darling name and story. In 1954, a 15-year-old girl from Chicago named Renny Powell submitted a blueberry coffee cake recipe to the Pillsbury $100,000 Recipe & Baking Contest (the precursor to today’s Pillsbury Bake-Off). Renny took second place in the junior division for her recipe, cleverly named “Boy Bait” for its habit-forming effect on young men.
Tender, easy to make, and jam-packed with berries, boy bait has been popular ever since. My version is updated with lemon zest to complement the flavor of the blueberries and a crunchy cinnamon streusel topping. You certainly don’t need to be a teenage boy to enjoy it, but I can attest that this 14-year-old loves it—so maybe Renny was onto something?

What You’ll Need To Make Blueberry Coffee Cake

Can I Use Frozen Blueberries?
Fresh blueberries are ideal for this coffee cake, but frozen will work, too. If you’re using frozen berries, fold them into the batter without thawing them first; otherwise, they can turn the batter purple. The cake may take a few extra minutes to bake with frozen berries, so check that a cake tester inserted into the center comes out clean.
How To Make Blueberry Coffee Cake
To begin, make the streusel topping by combining the brown sugar, flour, cinnamon, and salt in a small bowl.

Using your fingers, mix until no lumps of brown sugar remain, then add the cold butter.

Rub in the butter with your fingertips until the mixture reaches a crumbly state. Refrigerate until ready to use.

Next, whisk together the flour, baking powder, and salt. Set aside.

In the bowl of an electric mixer, beat the butter and granulated sugar until creamy, about 2 minutes.

Add the eggs one at a time, scraping down the sides of the bowl and beating well after each addition.

Beat in the vanilla extract and lemon zest.

Gradually add the flour mixture, alternating with the milk, beating on low speed to combine.

The batter will be quite thick.

Add the berries to the batter.

Fold gently with a spatula until evenly distributed. Do not over-mix.

Transfer the batter to the prepared pan and spread evenly.

Sprinkle the streusel topping evenly over the batter.

Bake for 40 to 45 minutes, until golden brown around the edges and a cake tester comes out clean.

Let cool in the pan on a rack for about 20 minutes, then serve right from the pan. Enjoy!

Make-Ahead, Storage & Freezing Instructions
This cake is best served on the day it is made, but leftovers will keep for a few days at room temperature, wrapped in foil.
To freeze, let the cake cool completely, then double-wrap it in aluminum foil or plastic freezer wrap, or place it in a heavy-duty freezer bag. Freeze for up to 3 months and thaw overnight on the countertop before serving.

So I made this tonite. Followed exactly. In 30 mins almost too well done. There was no flavor!!! I guess there was not enough sugar. Very disappointed. Will never use this again.
