Orly's Gluten Free Coffee Cake Crumb Muffins

This gluten-free coffee cake crumb muffins is one of the New York style baked goods that I created for the Orly the Baker gluten-free line at Chompies Restaurants in AZ.  If you don't want to make muffins, you can bake the batter into loaf pans and make a traditional coffee crumb cake.  The key ingredient in this recipe is the sour cream!


1 2/3 cups (215 grams) Sydney Blend
1 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
1/2 cup (113 grams) unsalted butter, softened
1 cup (200 grams) granulated white sugar
2 large eggs
1 teaspoon vanilla extract
3/4 cup (180 ml) sour cream or plain yogurt

Crumb Topping:
1 tablespoon cinnamon
1 1/2 cups (200 grams) Sydney Blend
1 2/3 (215 grams) white granulated sugar
1 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
1/2 cup (210 gram) melted butter or shortening

Heat: Preheat oven to 350 degrees F (180 degrees C). Line a 12-cup muffin tin with paper cups.

Mix: Mix together the Sydney Blend, sugar, cinnamon, baking powder, baking soda and salt.   Then add the melted butter and use your hands to rub the butter into the dry mixture.  Mix all ingredients together until the texture is crumbly.  In the bowl of your stand mixer with the paddle attachment, beat the butter until softened (about 1 minute). Gradually add the sugar and cream together until light and fluffy (about 3-4 minutes). Add the eggs, one at a time, beating well after each addition. Scrape down the sides of the bowl as needed. Beat in the vanilla extract. In a separate bowl whisk together the flour, baking powder, baking soda, and salt. With the mixer on low, add the flour mixture and sour cream alternately, starting and ending with the flour. Mix until fully incorporated.

Bake: Spoon or pipe the batter to fill ¾ of the muffin cups.  Fill the rest of the cups with the crumb topping on top of the batter. Bake for about 20-25 minutes, or until a toothpick inserted into the middle of the cake comes out clean.
