To find the percentage of cookies that contain peanuts, you can use the formula:

\[
\text{Percentage} = \left( \frac{\text{Number of cookies containing peanuts}}{\text{Total number of cookies}} \right) \times 100
\]

In this case, Liam has 7 cookies that contain peanuts out of a total of 20 cookies. Therefore, we can substitute the numbers into the formula:

\[
\text{Percentage} = \left( \frac{7}{20} \right) \times 100
\]

Now, calculate \( \frac{7}{20} \):

\[
\frac{7}{20} = 0.35
\]

Next, multiply by 100 to convert it to a percentage:

\[
0.35 \times 100 = 35
\]

Thus, the percentage of cookies that contain peanuts is:

\[
\boxed{35\%}
\]
