Step 1

Preheat oven to 325 degrees F (165 degrees C). Grease and flour a 10-inch bundt pan.

Step 2

Beat butter and sugar together in a large bowl with an electric mixer until light and fluffy. Beat one egg at a time into the butter mixture; add lemon extract with last egg.

Step 3

Sift together the flour, baking soda and salt. Alternately mix in the flour mixture and the yogurt, starting and ending with the dry ingredients. Beat just until incorporated.

Step 4

Pour batter into prepared pan. Bake in the preheated oven for 60 minutes, or until a toothpick inserted into the center of the cake comes out clean. Allow to cool 10 minutes in the pan, then turn out onto a wire rack and cool completely.
